If interactive forms are enabled, then the display layer takes care of
rendering the form elements. There is no need to draw them on the canvas
as well. This also leads to issues when values are prefilled, because
the text fields are transparent, so the contents that have been rendered
onto the canvas will be visible too.
We address this issue by passing the `renderInteractiveForms` parameter
to the render task and handling it when the page is rendered (i.e., when
the canvas is rendered).
1. Expanding divs to improve text selection. (Yury)
2. Adding enhanceTextSelection as an option.
3. Moving feature functionality from text_layer_builder.js to text_layer.js.
4. Added expandTextDivs method to only load expanded divs on first click, and only show on subsequent clicks
From the discussion in issue 7445, it seems that there may be cases where an API consumer would want to get the text content as is, without combined text items.
These have been found using `gulp lint` in combination with the `unused:
true` parameter for JSHint. Unfortunately there are too many false
positives to enable this feature, but now that most globals have been
removed because of the conversion to UMD the results are much more
useful than before.
I've seen the above error occasionally when the scale is updated many times in quick succession, but I've not been able to pinpoint exactly why it happens.
Since the error isn't caught, this means that the `pageViewDrawCallback` function doesn't run to completion.
Unfortunately, given the very intermittent nature of the issue, I haven't got any good STR for reliably reproducing this issue. However, I hope that this patch can be accepted anyway, since it's simple and should help prevent unnecessary errors.
This patch makes the naming consistent with the `TextLayerBuilder`, and also the new `AnnotationLayer`, and should thus help reduce possible confusion when working with the code.
Please note that the files were renamed using `git mv`, in order to preserve blame.
Additionally simplify the div creation logic (it needs to happen only
once, so it should not be in the for-loop) and remove/rename variables
for shorter code.
This patch goes a bit further than issue 6612 requires, and replaces all kinds of whitespace with standard spaces.
When testing this locally, it actually seemed to slightly improve two existing test-cases (`tracemonkey-text` and `taro-text`).
Fixes 6612.
Currently `getAnnotations` will *only* fetch annotations that are either `viewable` or `printable`. This is "hidden" inside the `core.js` file, meaning that API consumers might be confused as to why they are not recieving *all* the annotations present for a page.
I thus think that the API should, by default, return *all* available annotations unless specifically told otherwise. In e.g. the default viewer, we obviously only want to display annotations that are `viewable`, hence this patch adds an `intent` parameter to `getAnnotations` that makes it possible to decide if only `viewable` or `printable` annotations should be fetched.
In my opinion, this event shouldn't be dispatched in `PDFPageView.cssTransform`, since that would cause *two* events to be fired when "normal" zooming is used (once in `PDFPageView.cssTransform`, and once in `PDFPageView.draw`).
Fixes 6463.
This is a quick fix to get `scrollIntoView` working again for search results, but we really ought to re-write that function since it seems way too brittle.
Fixes 6596.
*This regressed in PR 4920.*
The main motivation for PR 4920 was to quickly get rid of old canvases when pages are evicted from the `PDFPageViewBuffer` cache. However it inadvertently broke the use-case where the `canvas` is used as a preview, on scale or rotation changes, until the re-rendering is finished.
Fixes 6467.
In PR 5552, specifically commit 9f384bbb41, the meaning of `this.annotationLayer` changed in `PDFPageView`. Previously it referred directly to a DOM element, but now it's instead an instance of `AnnotationsLayerBuilder`.
This patch tweaks things so that we won't try to hide a non-existent `annotationLayer` div in `PDFPageView_reset`, and also so that we don't attempt to insert empty (`null`) DOM elements in `PDFPageView_draw`.
In Blink-based browsers, there is a mismatch between document size and
paper size. Even if exactly the same values and unit are used, it is
possible that the printed results takes more pages than expected.
To solve the issue, the page size is set via @page size, and the canvas
and ancestor nodes are assigned a width+height of 100% (=relative to the
page). This change resolves bugs such as blank pages and split pages.
Set transformation matrix in (polyfilled) mozPrintCallback when a scale
is applied. Removed _scaleX and _scaleY in favor of _transformMatrix to
emphasize that the caller MUST ensure that the state of the matrix is
correct before `addContextCurrentTransform` is called.
In old versions of the viewer, anchor links were used to be able to scroll a page into view. Since we for quite some time have had a `scrollIntoView` function which handles this, the anchor links are no longer necessary and I believe that they can be removed. Doing so will reduce the total number of DOM elements in the viewer.
For most documents this patch will probably not make much of a difference performance wise, but for very long (1000+ pages) documents this could help performance especially on lower powered hardware.
