By leveraging import maps we can get rid of *most* of the remaining `require`-calls in the `src/display/`-folder, since we should strive to use modern `import`-statements wherever possible.
The only remaining cases are Node.js-specific dependencies, since those seem very difficult to convert unless we start producing a bundle *specifically* for Node.js environments.
With the changes in the previous patch the `isNodeJS`-helper no longer needs to live in its own file, which helps get rid of a closure in the *built* files.
In the last couple of years we've been quicker to remove support for older browsers/environments, which means that at this point in time we don't bundle that many polyfills. (The polyfills are also generally simpler nowadays, ever since we removed support for e.g. Internet Explorer.)
Rather than having to *manually* handle the polyfills, we can actually let Babel take care of bundling the necessary polyfills for us; please refer to https://babeljs.io/docs/babel-preset-env
The only exception here is the Node.js-specific compatibility-code, which is moved into the `src/display/node_utils.js` file. This ought to be fine since workers are not available/used in Node.js-environments.
*Please note:* For the `legacy`-builds this will increase the size of the *built* files, however that seems like a very small price to pay in order to simplify maintenance of the general PDF.js library.
Localization of this button broke in PR 16340, which I assume was completely accidental, since the download-button now tries to access a l10n-id that was removed some time ago (see PR 15617).
Note how loading even the development viewer, i.e. http://localhost:8888/web/viewer-geckoview.html#locale=en-US, currently logs l10n-warnings on the `master` branch.
Having a `require` in this file has never made sense in e.g. the Firefox PDF Viewer and shouldn't really be necessary.
Possibly the idea was to facilitate some kind of third-party bundling, however the *built* `pdf.js` file has always exposed the API-contents globally.
Currently this class contains a few "special" code-paths for the COMPONENTS build-target, which normally wouldn't be a problem. However, in this particular case that means accessing code that we don't want to include unconditionally in all builds.
This is currently implemented using build-time `require`-calls which we nowadays want to avoid, and we should strive to remove all such cases from the code-base. (Generally speaking `import` is the future, and build-tools may not always play well with a mix of both formats.)
We can easily improve things here by using sub-classing for the COMPONENTS build-target, and then use the ability to re-name when exporting (to avoid breaking existing code).
Occasionally some test-suites may fail to start on the bots, however that's not correctly reflected in the botio-output posted to GitHub which makes it easy to accidentally overlook this situation.
Looking at the raw logs when that happens they always seem to contain a line such as `Run NaN tests` which means that we should be able to easily make this situation a *failure* as intended.
In order to reproduce the issue:
- scale down the image
- zoom the page and the image is pixellated
So this patch allow to redraw the image when zooming.
- Take into account the page translation,
- Take into account the correct translation for the editor border,
- Take into account the position of the first glyph in the annotation,
- Take into account the rotation of the editor.
Close#16633.
There's no good reason for getting this option multiple times in the same method. Also, we can slightly re-factor how the `editorStampButton` is made visible.
- Do the /Filter and /DecodeParms lookup in parallel, since that ought to be a *tiny* bit more efficient.
- Avoid code-duplication when `CompressionStream` isn't supported, since we already have a fallback code-path at the end of the function.
This regressed in PR 16659, when the signature of the `PDFViewer.annotationEditorMode`-setter was changed, and it currently leads to an Error being thrown when exiting PresentationMode.
