This commit reduces the number of freetext editor integration test suite
failures, in full isolation, from 6 to 5 by fixing the following issues
in the "create editor with keyboard" block:
- The second test relied on the first test to enable freetext editing
mode and put focus on the page (annotation layer). For isolation we
now do that explicitly in the second test.
- The second test relied on the first test for the editor numbering. For
isolation we change the editor numbering to the one after initial
document load.
Moreover, the test names have been updated to clarify with scenario is
being tested, which came up during comparison of the changes against
commit ea5eafa to make sure that we are still testing the originally
intended scenarios (confirmed by disabling the relevant code from the
commit per scenario and noticing the corresponding test failing).
This commit reduces the number of freetext editor integration test suite
failures, in full isolation, from 8 to 6 by fixing the following issues
in the "move editor with arrows" block:
- The second and third test relied on the first test to enable freetext
editing mode. For isolation we now do it explicitly in both tests.
- The second test relied on the first test having created an editor. For
isolation we now create the editor explicitly in the second test.
- The third test relied on the previous tests for the editor numbering.
For isolation we change the editor numbering to the one after initial
document load. Since we can't have state (editors) from a previous
test anymore we can remove the `clearAll` call as well.
With this patch, all the paths components are collected in the worker until a path
operation is met (i.e., stroke, fill, ...).
Then in the canvas a Path2D is created and will replace the path data transfered from the worker,
this way when rescaling, the Path2D can be reused.
In term of performances, using Path2D is very slightly improving speed when scaling the canvas.
To avoid being able to introduce dependencies between tests, and to
bring existing dependencies to the surface, this commit makes sure that
we close the document between tests so that we can't accidentally rely
on state set by a previous test. This prevents multiple tests from
failing if one of them fails and makes debugging easier by being able to
run each test on their own independent of other tests.
This commit, combined with the previous ones, is enough to make the
scripting integration test suite pass consistently if random mode in
Jasmine is enabled, proving that the tests are fully isolated now.
The integration tests are order-dependent because they rely on input
field state set by a previous test. This commit fixes the issue by
updating the values to match the initial state of the document, which
makes sure that we don't build upon values from previous tests while
still testing the intended logic in the individual tests like before.
By checking for the expected value directly we can shorten the code, and
it simplifies removing the dependencies between the tests in the next
commit (by having fewer places to change). Note that this follows the
same pattern as PRs #19192, #19001 and #18399 and also helps to remove
any further possibilities for intermittent failures.
Currently the MD5 computation doesn't actually work (at all?), since we're invoking the `calculateMD5` function without providing all of the necessary parameters and the PDF-data thus isn't taken into account.
Fixing this caused unit-tests to fail, which isn't that surprising since the current date/time is used in the MD5 computation, and we thus utilize Jasmine to work-around that.
This integration test fails intermittently because of concurrent
clipboard access due to running the test in parallel in both browsers.
It can be reproduced by introducing `await waitForTimeout(1000)` between
the copy and paste operations.
This commit fixes the issue by running the test sequentially instead,
mirroring the change from commit 0e94f2bd.
The new API-functionality will allow a PDF document to be downloaded in the viewer e.g. while the PasswordPrompt is open, or in cases when document initialization failed.
Normally the raw data of the PDF document would be accessed via the `PDFDocumentProxy.prototype.getData` method, however in these cases the `PDFDocumentProxy`-instance isn't available.
Having some interactive elements forces the screen readers to switch to form mode
and consequently they delegate the keyboard stuff to the browser.
This patch sets an aria label on each editor in order to have a better description than just
'application'.
Currently we lookup the `devicePixelRatio`, with fallback handling, in a number of spots in the code-base.
Rather than duplicating code we can instead add a new static method in the `OutputScale` class, since that one is now exposed in the API.
This patch extends the approach of PR 14543, by also treating e.g. minus signs followed by '(' or '<' as zero.
Inside of a /Contents stream those characters will generally mean the start of one or more glyphs.
When the DOM structure of the viewer was updated in PR 18385 it caused the `secondaryToolbar` to accidentally start closing when clicking inside of it, since the `secondaryToolbar` now reside *under* the `toolbar` in the DOM.
**Steps to reproduce:**
- Open the viewer.
- Open the `secondaryToolbar`.
- Try to change document rotation at least *twice*.
**Expected behaviour:**
The document rotation can be changed an arbitrary number of times.
**Actual results:**
The `secondaryToolbar` closes after changing rotation just once.
For Type3 glyphs with `d1` operators it's easy to compute a fallback bounding box, however for `d0` the situation is more difficult.
Given that we nowadays compute the min/max of basic path-rendering operators on the worker-thread, we can utilize that by parsing these Type3 operatorLists to guess a more suitable fallback bounding box.
One of the images have a corrupt SMask, where the /Height-entry is bogus; see the excerpt below (via https://brendandahl.github.io/pdf.js.utils/browser/).
```
SMask (stream) [id: 17, gen: 0]
ColorSpace = /DeviceGray
Height = /Length
Subtype = /Image
Filter = /FlateDecode
Type = /XObject
Width = 157
Matte (array)
BitsPerComponent = 8
Length = 3893

```
Hence we enable SMask/Mask images to fallback to the parent image dimensions, and also add more validation of the width/height to get a better error message when that data is wrong.
Currently we have a number of spots in the code-base where we need to clamp a value to a [min, max] range. This is either implemented using `Math.min`/`Math.max` or with a local helper function, which leads to some unnecessary duplication.
Hence this patch adds and re-uses a single helper function for this, which we'll hopefully be able to remove in the future once https://github.com/tc39/proposal-math-clamp/ becomes generally available.
The current logic assumes that all spans in the text layer contain
only one text node, and thus that the position information
returned by `highlighter._convertMatches` can be directly used
on the element's only child.
This is not true in case of highlighted search results: they will be
injected in the DOM as `<span>` elements, causing the `<span>`s
in the text layer to have more than one child.
This patch fixes the problem by properly converting the (span, offset)
pair in a (textNode, offset) pair that points to the right text node.
