Generated Gif Has Invalid Header

All modalities in radiology practice have turn into digital, and due to this fact cope with DICOM pictures. A DICOM file consists of a header and picture data sets packed into a single file. The data throughout the header is organized as a constant and standardized series of tags. By extracting data from these tags one can entry important info regarding the patient demographics, examine parameters, and so forth. In the curiosity of affected person confidentiality, all information that can be used to determine the patient must be removed before DICOM photographs are transmitted over a community for academic or different purposes. In addition to the DICOM format, the radiologist routinely encounters images of several file formats corresponding to JPEG, TIFF, GIF, and PNG. Each format has its personal unique benefits and drawbacks, which should be considered when images are archived, utilized in instructing files, or submitted for publication. Knowledge about these codecs and their attributes, corresponding to picture resolution, picture compression, and picture metadata, helps the radiologist in optimizing the archival, organization, and show of photographs. This article aims to extend the awareness among radiologists concerning DICOM and other picture file formats encountered in scientific practice. It also suggests a quantity of tips and tips that can be utilized by the radiologist in order that the digital potential of those photographs may be fully utilized for maximization of workflow within the radiology practice. Although GIF was not designed as an animation medium, its ability to store multiple photographs in one file naturally advised using the format to retailer the frames of an animation sequence. To facilitate displaying animations, the GIF89a spec added the Graphic Control Extension , which permits the pictures in the file to be painted with time delays, forming a video clip. Each body in an animation GIF is launched by its own GCE specifying the time delay to wait after the body is drawn. Global info initially of the file applies by default to all frames. The information is stream-oriented, so the file offset of the beginning of every GCE is dependent upon the length of previous knowledge. Within each body the LZW-coded picture information is arranged in sub-blocks of up to 255 bytes; the scale of every sub-block is said by the byte that precedes it. Images in other codecs such as JPEG even have small bits of data – called metadata – written into the image file. Thus, if one desires to kind an image collection by date, a software bundle that can entry the EXIF metadata is required.

IPTC stands for International Press Telecommunications Council, the group that developed this normal. The IPTC Information Interchange Model is a file construction and set of metadata attributes that can be utilized to textual content, photographs, and different media sorts. These attributes have gained close to common acceptance amongst photographers for embedding info into images. Param Required Type Description client_id required string Your shopper ID. redirect_uri required URI Your registered redirect URI. This must precisely match the redirect URI registered in the prior, Registration step. Response_type required string This must be "code", to return an entry token utilizing authorization code grant. State elective string Your unique token, generated by your utility. This is an OAuth 2.zero opaque value, used to avoid CSRF assaults. If the user authorizes your utility, the person is redirected to your redirect URI. The authorization code shall be returned along the redirect URI.

The header is adopted by a single attribute that incorporates all of the pixel depth data for the picture. These knowledge are saved as an extended series of 0s and 1s, which can be reconstructed because the image through the use of the data from the header. This attribute may include info regarding a single image, multiple frames of a study, or a cine loop, relying on the modality that has generated the picture. TransformationStringA transformation to use to the slideshow after it has been generated. When overwriting property, should you embrace variations in your supply URLs, you will need to replace the URLs with the brand new model quantity to deliver the new asset. If you do not embody variations, you will need to invalidate the old belongings on the CDN server cache. The User-Agent request-header area accommodates details about the consumer agent originating the request. This is for statistical purposes, the tracing of protocol violations, and automatic recognition of person brokers for the sake of tailoring responses to avoid particular consumer agent limitations. The area can comprise multiple product tokens (section three.8) and feedback figuring out the agent and any subproducts which form a significant part of the person agent. By conference, the product tokens are listed in order of their significance for figuring out the application. The GIF format appears to have been designed with the concept that viewers would render a number of photographs in a GIF on a typical canvas, giving an effect like an image wall. Each picture, in addition to top and width, also has 'left' and 'top' cordinates specifying where it is to be positioned on the canvas.

Portable Document Format is a versatile, cross-platform, cross-application file format. Based on the PostScript imaging mannequin, PDF files accurately show and preserve fonts, web page layouts, and both vector and bitmap graphics. In addition, PDF information can comprise electronic doc search and navigation options such as digital hyperlinks. Adobe Acrobat also has a Touch Up Object device for minor enhancing of pictures in a PDF. For more information about working with pictures in PDFs, see Acrobat Help. When the no-cache directive is current in a request message, an application SHOULD forward the request toward the origin server even if it has a cached copy of what is being requested. This pragma directive has the same semantics because the no-cache cache-directive (see section 14.9) and is outlined here for backward compatibility with HTTP/1.zero. Clients SHOULD include both header fields when a no-cache request is distributed to a server not recognized to be HTTP/1.1 compliant. The precise which means of this header field is dependent upon the implementation of the origin server and the nature of the original useful resource. For recordsdata, it may be simply the file system last-modified time. For entities with dynamically included components, it might be the newest of the set of last-modify occasions for its element components. For database gateways, it may be the last-update time stamp of the report. For digital objects, it may be the final time the interior state modified. If a quantity of encodings have been utilized to an entity, the content material codings MUST be listed within the order in which they had been applied.

Additional details about the encoding parameters MAY be supplied by different entity-header fields not defined by this specification. For occasion, Imgur makes use of its personal GIFV format, which is actually an MP4 video encapsulated as a component in an HTML 5 document, which is served with a .gifv extension. The specific methodology is used to use actions to already uploaded belongings. You can also use this method to pre-generate transformations for remotely fetched images. I removed both the global image table and the graphic management extension, and then no matter what shade the pixel originally was, it comes out black. From there, I took it a step further, as a result of the usual never says you must actually set any pixels in the image, I removed the LZW encoded image knowledge. I left the required lzw code-size header and block terminator, as a result of without these Firefox and the GIMP both complained it wasn't a legitimate GIF, after which I had it. If a number of encodings have been applied to an entity, the transfer- codings MUST be listed within the order by which they have been utilized. The Server response-header subject contains details about the software utilized by the origin server to deal with the request. The subject can include multiple product tokens (section 3.8) and comments figuring out the server and any significant subproducts. The product tokens are listed so as of their significance for identifying the application. A shopper MUST embrace a Host header subject in all HTTP/1.1 request messages . If the requested URI doesn't embody an Internet host name for the service being requested, then the Host header area MUST be given with an empty value. An HTTP/1.1 proxy MUST be certain that any request message it forwards does include an appropriate Host header area that identifies the service being requested by the proxy. All Internet-based HTTP/1.1 servers MUST respond with a four hundred status code to any HTTP/1.1 request message which lacks a Host header area. The Accept request-header subject can be utilized to specify certain media types that are acceptable for the response. Accept headers can be used to indicate that the request is particularly restricted to a small set of desired sorts, as within the case of a request for an in-line image. Response header invalidation is Oracle Web Cache performance that permits an origin server to return a transactional response whose response physique contains something other than HTML. This is a circumstance by which ESI inline invalidation doesn't work; Oracle Web Cache can only use ESI invalidation tags at the aspect of a response physique that incorporates HTML.

With response header invalidation, origin servers can send invalidation directives in a proprietary invalidation response header. Radiance is a 32‑bits-per-channel file format used for HDR photographs. This format was initially developed for the Radiance system, knowledgeable device for visualizing lighting in digital environments. The file format stores the amount of light per pixel instead of just the colours to be displayed onscreen. The levels of luminosity accommodated by the Radiance format are far greater than the 256 levels in 8‑bits-per-channel picture file codecs. OpenEXR is a file format utilized by the visible effects trade for HDR images. The movie format has excessive colour constancy and a dynamic vary appropriate for use in movement picture production. Developed by Industrial Light and Magic, OpenEXR supports a quantity of lossless or lossy compression strategies. An OpenEXR file supports transparency and works only with 32 bits/channel images; the file format stores the values as sixteen bits/channel floating level. Graphics Interchange Format is the file format generally used to show indexed-color graphics and images in HTML documents.

GIF is an LZW-compressed format designed to minimize file measurement and electronic transfer time. GIF format preserves transparency in indexed-color images; however, it doesn't help alpha channels. By default, Octave's image IO capabilities use the GraphicsMagick library for his or her operations. Because of this, the functionimformats keeps a configurable list of accessible formats, their extensions, and what functions should the picture IO features use. This allows one to expand Octave's picture IO capabilities by creating capabilities aimed toward appearing on specific file formats. The metadata parameter of an uploaded asset incorporates a map or pipe-separated listing of key-value pairs of custom predefined metadata fields. The metadata methodology can be utilized to add values to these metadata fields. The container is a set of object implemented using template lessons, this is known as OMContainers. OMUContainers is just like OMContainers except that templates aren't used, this can help scale back code measurement considerably however could trigger significant kind casting operations. If your target/cross-compiler (e.g. eC++) does not help template-based containers, you then would possibly contemplate to make use of OMUContainers instead and rebuild OXF with OM_NO_TEMPLATES_USAGE choice. A cache MAY assume that the identical selection shall be made for future requests with the identical values for the listed area names, during time for which the response is fresh. The TE request-header area indicates what extension transfer-codings it's willing to merely accept within the response and whether or not or not it is prepared to simply accept trailer fields in a chunked transfer-coding. Its worth might include the keyword "trailers" and/or a comma-separated listing of extension transfer-coding names with elective settle for parameters (as described in part 3.6).

It also allows out of date or mistyped links to be traced for upkeep. The Referer area MUST NOT be sent if the Request-URI was obtained from a supply that does not have its own URI, corresponding to enter from the person keyboard. The Content-MD5 header area MAY be generated by an origin server or consumer to perform as an integrity examine of the entity-body. Only origin servers or clients MAY generate the Content-MD5 header field; proxies and gateways MUST NOT generate it, as this would defeat its value as an end-to-end integrity examine. Any recipient of the entity- body, including gateways and proxies, MAY verify that the digest value on this header area matches that of the entity-body as received. An origin server can retailer multiple invalidation response headers in its response to Oracle Web Cache. When this happens, an Oracle Web Cache entry solely must match one header to qualify for invalidation. In different words, the content of multiple invalidation response headers in the identical response are treated as if they have been a half of a single response header joined by commas. Search terms may merely be words or phrases typed by the user. Users can even add the @ signal earlier than a GIPHY username to return content from a specific GIPHY channel. All special characters should be supported and not re-encoded in your search request. There are over 100 formats described to retailer pictures, most of them being proprietary. The extra in style codecs utilized in day by day follow are the JPEG, JPEG 2000, TIFF, GIF, and PNG codecs. In contrast to DICOM pictures, pictures saved in these codecs could be seen on any private pc without the necessity for dedicated viewers. They can be easily included into displays and Web pages. Image information saved in these formats are devoid of cumbersome header info and often comprise 8-bit information.

These information therefore require less space for storing and demand less useful resource to switch over a network or via the Internet. One big drawback of these file codecs, in comparison with DICOM, is that they comprise a user-determined window degree and window width that is set on the time of creation of the picture. Consequently, the contrast between structures within the image can't be adjusted and postprocessing can't be performed on these photographs. As described earlier, such demographic info of the patient and a bunch of other details about the imaging study is encoded within a picture header. The data might or will not be displayed on the display screen, but the information could be extracted from the header by anyone who has entry to the DICOM file. Several instructional resources utilizing DICOM recordsdata can be found for radiology college students on the World Wide Web. Creating and accessing such digital educating information usually contain transmission of DICOM data over the Internet. In the interest of affected person confidentiality, all information identifying the patient ought to be faraway from the DICOM header when a DICOM file is uploaded for such purposes. The size and colour high quality of animated GIF information can differ considerably depending on the applying used to create them. Strategies for minimizing file measurement include utilizing a standard global colour table for all frames and minimizing the variety of pixels lined in successive frames . More advanced methods contain modifying shade sequences to better match the existing LZW dictionary, a type of lossy compression. Simply packing a collection of unbiased body photographs right into a composite animation tends to yield giant file sizes. Tools are available to minimize the file size given an present GIF. By default, an animation displays the sequence of frames solely once, stopping when the last body is displayed. This block, placed instantly earlier than the sequence of animation frames, specifies the variety of instances the sequence of frames must be played or that it should repeat repeatedly . Support for these repeating animations first appeared in Netscape Navigator model 2.zero, after which spread to other browsers. Most browsers now recognize and help NAB, although it's not strictly a part of the GIF89a specification. A small colour desk may suffice for small pictures, and keeping the colour desk small permits the file to be downloaded faster. Both the 87a and 89a specifications permit color tables of 2n colours for any n from 1 through eight. Most graphics functions will learn and display GIF pictures with any of these desk sizes; but some don't assist all sizes when creating images.

Firestore Timestamp Created At And Updated At

I want a subset of my Firestore documents to have exact copies inside of an Algolia search index. However, currently without this feature, I would have inconsistent client reading. In summary, I read document A from two different API's and get back two different types for the same timestamp field.

firestore timestamp created at and updated at - I want a subset of my Firestore documents to have exact copies inside of an Algolia search index

This would be equivalent to the RTDB's firebase.database.ServerValue.TIMESTAMP. So if time values are to be Timestamps, why not just add firebase.firestore.fieldValue.serverTimestampAsMilliseconds() as you've suggested? The problem is that creates a choice for users that almost universally don't need need to make it. Users will have to ask themselves which format they prefer when for all the reasons above we believe they really should prefer timestamps. We'd get support questions about which to prefer when, etc.

firestore timestamp created at and updated at - However

Meanwhile note that we support 10 client languages so "just" doing anything is a lot of work. When I changed my system time to an incorrect time and then ran the code below, it was storing the same timestamp for both clientDate and serverTimestamp fields. Previous questions answer how to convert a single Timestamp or a single timestamp in multiple documents in a snapshot.

firestore timestamp created at and updated at - In summary

But I haven't found a generalized approach for converting all Timestamps within a snapshot when multiple Timestamps exist. 🚀 The wrapper type all read and write operations, query field path, field value, collection path, document path. Set creates or overwrites the document with the given data. See DocumentRef.Create for the acceptable values of data. Without options, Set overwrites the document completely. Specify one of the Merge options to preserve an existing document's fields.

firestore timestamp created at and updated at - This would be equivalent to the RTDB

To delete some fields, use a Merge option with firestore.Delete as the field value. Documents are individual pieces of data in our database. You can think of documents to be much like simple JavaScript objects. They consist of key-value pairs, which we refer to as fields. The values of these fields can be strings, numbers, Booleans, objects, arrays, and even binary data.

firestore timestamp created at and updated at - So if time values are to be Timestamps

Firestore stores data within "documents", which are contained within "collections". Documents can also contain nested collections. For example, our users would each have their own "document" stored inside the "Users" collection. The collection method allows us to reference a collection within our code. Another approach that has previously worked is set out in this post.

firestore timestamp created at and updated at - The problem is that creates a choice for users that almost universally don

The answer and the firebase documents suggest that the timestamps only work with .set and .update, whereas I'm trying to use it with .add. Perhaps something has changed in firebase so the it no longer works with .add - but I tried adding a .set step after my .add step and that didn't work either. Cloud Firestore is a blazing-fast, serverless NoSQL database, perfect for powering web and mobile apps of any size.

Grab the complete guide to learning Firestore, created to show you how to use Firestore as the engine for your own amazing projects from front to back. The timestamp object you get from firestore has a toDate () method you can use. Convert a Timestamp to a JavaScript Date object.

firestore timestamp created at and updated at - We

This conversion causes a loss of precision since Date objects only support millisecond precision. Returns Date JavaScript Date object representing the same point in time as this Timestamp, with millisecond precision. FieldValue.serverTimestamp () is probably the most common FieldValue that you'll encounter.

firestore timestamp created at and updated at - Meanwhile note that we support 10 client languages so

There are a few different types of FieldValue s, and they all act as tokens when writing Firestore document fields. These tokens don't have a specific value on the client — they are evaluated on the server, at which point the final value is known. When writing mobile apps, saving the data users enter is critical. You can save the data locally, but doing so means you can't save it permanently or share it with others.

firestore timestamp created at and updated at - When I changed my system time to an incorrect time and then ran the code below

If you want to share your data, you need to save it in the cloud. One of the easiest solutions is Google's Cloud Firestore database. Merge returns a SetOption that causes only the given field paths to be overwritten. Other fields on the existing document will be untouched. It is an error if a provided field path does not refer to a value in the data passed to Set.

Will not get flattened and will not have its field path built nor you can use field value . Read Firestore append to array an object with server timestamp and How to increment a map value in a Firestore array, both are negative. We can of course create our own date values using JavaScript, but using a server timestamp lets us know exactly when data is changed or created from Firestore itself. The .add method returns a promise and from this resolved promise, we get back a reference to the created document, which gives us information such as the created id. Once you've done that, we will start in test mode and enable all reads and writes to our database.

firestore timestamp created at and updated at - But I havent found a generalized approach for converting all Timestamps within a snapshot when multiple Timestamps exist

In other words, we will have open access to get and change data in our database. If we were to add Firebase authentication, we could restrict access only to authenticated users. You can access that document as a DocumentReference in the ref property of the snapshot returned to your function. Firestore lets you execute multiple write operations as a single batch that can contain any combination of set, update, or delete operations. Cloud Firestore gives you the ability to read the value of a collection or a document. This can be a one-time read, or provided by realtime updates when the data within a query changes.

firestore timestamp created at and updated at -  The wrapper type all read and write operations

Similar to adding a new pet, this method uses the collection reference to update an existing pet using its ID. If the field is not an integer or double, or if the field does not yet exist, the transformation will set the field to the given value. If the operands are equivalent (e.g. 3 and 3.0), the field does not change. The minimum of a zero stored value and zero input value is always the stored value.

firestore timestamp created at and updated at - Set creates or overwrites the document with the given data

The minimum of any numeric value x and NaN is NaN. The maximum of a zero stored value and zero input value is always the stored value. The maximum of any numeric value x and NaN is NaN. This client is built around references to collections and documents. CollectionRefs and DocumentRefs are lightweight values that refer to the corresponding database entities. Creating a ref does not involve any network traffic.

firestore timestamp created at and updated at - See DocumentRef

In Firestore, documents are sets of key-value pairs, and collections are groups of documents. A Firestore database consists of a hierarchy of alternating collections and documents, referred to by slash-separated paths like "States/California/Cities/SanFrancisco". UpdatedAt field path is updated and the value is Firestore server timestamp.

firestore timestamp created at and updated at - Without options

CreatedAt field path is created, and the value is Firestore server timestamp. Auto add createdAt and updatedAt server timestamp to create and add operation. In this lesson, we use the Firstore server timestamp to set the publishedAt property on newly created posts.

firestore timestamp created at and updated at - Specify one of the Merge options to preserve an existing document

While Date.now() is readily available in Javascript the serverTimestamp ensures better consistency and accuracy for the timestamps. Within onSnapshot's callback, we get direct access to the snapshot of our collection, both now and whenever it's updated in the future. Try manually updating our one document and you'll see that .onSnapshot() is listening for any changes in this collection. Initialize Cloud Functions and deploy an onCreate function that reads the metadata in a transaction, then updates both documents atomically.

firestore timestamp created at and updated at - To delete some fields

The transaction will only complete if it can safely read the metadata and make all the updates without being conflicted by other activity in the database. In order for this to work well at scale, we need to run the write as a transaction. We also need a separate document to serve as single source of truth to guarantee an accurate count when adding a new record to the database. I usually keep documents like this in a separate collection like metadata/ to keep track of aggregate data about the collection.

firestore timestamp created at and updated at - Documents are individual pieces of data in our database

The easiest way to order by creation time is to use a server timestamp. This tells Firestore to add a date to the document based on Google Cloud's backend time, so you're not relying on the client's clock . The follow snippet contains strategies for ordering a collections sequentially. For example, you may want a field that increases by 1 after each new document is created. Cloud Firestore does not provide automatic ordering on the auto-generated docIDs, so we need be clever to solve this problem . If you are a beginner or would want to try out the magic with cloud firestore for web, get started in this codelab here.

firestore timestamp created at and updated at - You can think of documents to be much like simple JavaScript objects

The code snippet shows below how to send some "fetched" or"submitted" data to Cloud Firestore, this could be inputs from a form. Transactions are useful when you want to update a field based on its current value, or the value of another field. If you want to write multiple documents without using the documents current state, a batch writeshould be used. A DocumentSnapshot is returned from a query, or by accessing the document directly.

firestore timestamp created at and updated at - They consist of key-value pairs

Even if no document exists in the database, a snapshot will always be returned. Commit applies all the writes in the batch to the database atomically. Commit returns an error if there are no writes in the batch, if any errors occurred in constructing the writes, or if the Commmit operation fails. StartAfter returns a new Query that specifies that results should start just after the document with the given field values. The values at the given field paths are replaced, but other fields of the stored document are untouched.

firestore timestamp created at and updated at - The values of these fields can be strings

Snapshots returns an iterator over snapshots of the document. Each time the document changes or is added or deleted, a new snapshot will be generated. To update some fields of an existing document, use Update. It takes a list of paths to update and their corresponding values. Anyway, do not resort to array of objects types easily, create a new collection instead.

firestore timestamp created at and updated at - Firestore stores data within

Always keep your data type straightforward if possible. When I attempt to update a firestore document with any date object, the operation just clocks indefinitely. The flip side of this question is how hard is it for users to deal with this if they don't like it?

firestore timestamp created at and updated at - Documents can also contain nested collections

For example how hard is it to get from a Date to milliseconds? This is already well supported by the existing date types and is straightforward. It's easy enough to tell if a given value has a timestamp type and apply the conversion you like. Since ServerValue.TIMESTAMP or FieldValue.serverTimestamp() would not save to Firestore I used Date() as a workaround to set the timestamp. I used the Firestore @ServerTimestamp annotation to save the Date type field to my Firestore database.

firestore timestamp created at and updated at - For example

If it worked for updates it would be a sufficient workaround. All you need is to import 'firebase' and then callfirebase.firestore.FieldValue.serverTimestamp() wherever you need it. Be careful with the spelling though, its "serverTimestamp()". In this example it provides the timestamp value to 'createdAt' when uploading to the firestore's product's collection. For example, we can generate a timestamp for whenever a given document is created or updated with the following helper from the FieldValue property.

firestore timestamp created at and updated at - The collection method allows us to reference a collection within our code

If we don't, there'll be an error in getting our document data. The way to check and see if our document exists is by saying, if doc.exists, which returns a true or false value. To get access Firestore use all of the methods it provides, we use firebase.firestore(). This method need to be executed every time we want to interact with our Firestore database. After that, we'll be taken to our database itself, where we can start creating collections and documents. The root of our database will be a series of collections, so let's make our first collection.

firestore timestamp created at and updated at - Another approach that has previously worked is set out in this post

Sets of these documents of these documents are known as collections. Collections are very much like arrays of objects. Within a collection, each document is linked to a given identifier .

firestore timestamp created at and updated at - The answer and the firebase documents suggest that the timestamps only work with

We found indications that firebase-firestore-timestamp is an Inactive project. See the full package health analysisto learn more about the package maintenance status. Firestore provides out of the box support for offline capabilities.

firestore timestamp created at and updated at - Perhaps something has changed in firebase so the it no longer works with

When reading and writing data, Firestore uses a local database which automatically synchronizes with the server. Cloud Firestore functionality continues when users are offline, and automatically handles data migration when they regain connectivity. On a high traffic application, the value on the server could have already changed by the time the write operation sets a new value, causing the number to be inconsistent. You just created an instance of DataRepositorty in the above code. This will be used shortly for updating and deleting the data in the Firestore database.

What Movie Theaters Are Open Now

Take, for example, the news that the Lakewood Ranch Cinemas will be screening movies once more beginning with a "soft" reopening March 31 and the official opening date of Friday, April 2. Meanwhile, Sarasota's SFS venue, downtown's Burns Court Cinema, is still working on plans to open its doors to lovers of independent and foreign films again soon. After the escalation of the novel coronavirus pandemic, the shutdown of businesses across America, and the delay of major tentpole releases previously scheduled throughout 2020, new movies are now opening exclusively in theaters again. But as the disease recirculates in waves, chains like AMC, Regal, and Cinemark have struggled, with some theaters reopening and then shuttering again, while others closed permanently. As COVID-19 continues to be a prevalent issue in many parts of the United States and around the world, the safety, practicality, and availability of movie theaters remains in question.

what movie theaters are open now - Take

Canada's largest movie theaters over the years have been located in Toronto. As mentioned above the 18- (later 21-) screen Cineplex was the movie theater with the most screens in the world until the late 1980s, but remained the largest movie theater in Canada until it was closed at the turn of the 21st century. In 1998, AMC expanded to Canada, building large movie theatres with as many as 24 screens before opening a 30-plex there in 1999, which is the AMC Interchange 30. Then in 2008, the 24-screen AMC Yonge Dundas 24, adjacent to the Eaton Centre, was completed. Cineplex Entertainment purchased the theater in 2012, along with several other Canadian AMC megaplexes, bringing the company full circle.

what movie theaters are open now - Meanwhile

Any place where people gather together was hit hard by the pandemic. But movie theaters, being almost exclusively indoor-only locations have had a more difficult time than other industries finding ways to adjust. Theaters are open around the nation now, although seating is still largely limited to a fraction of maximum capacity, and there still isn't all that much being released in theaters to go see.
