Because of https://bugzilla.mozilla.org/show_bug.cgi?id=1582545, the padding-inline is by default 0.
0 is not really enough because of the outline, so just set it to 2px (it was 4px before the patch)
in order to have something visually correct.
The default outline for a focused text input is not that bad but for any reason when changing
the background color, all the good default border/outline properties are lost (it's the same
behaviour in Edge).
So in order have something consistent in HCM/non-HCM, a 2px-border+1px-outline (on @MReschenberg
advices) is added when an input is focused with different colors depending on HCM.
While working on the above issue, I noticed few bugs I fixed when in HCM:
- input, button and select have some default properties which have been created at a time where
annotation layer didn't exist, hence this patch remove them and set those properties where
they should live;
- some elements (like the main toolbar) is using a box-shadow which is invisible in HCM, hence
it's replaced by a border-bottom in HCM;
- some separators are invisible in HCM, hence use GrayText color to render them correctly;
- the options for the zoom selection were invisible in HCM with Desert (one of the Windows 11
themes).
There were some links not working in some XFA files,I realized that the anchor tag that contains the link has an inline display and couldn't receive any height, solved this by adding a "position: absolute". Tested with two different files in Firefox Nightly and Chrome and now all links are working perfectly fine. Added reftest to avoid future regressions
- it aims to fix https://bugzilla.mozilla.org/show_bug.cgi?id=1716758;
- some buttons have a JS action with the pattern `app.launchURL(...)` (or similar) so extract when it's possible the url and generate a <a> element with the href equals to the found url;
- pdf.js already had some code to handle that so this patch slightly refactor that.
Moves the logic out of TextLayerBuilder to handle
highlighting matches into a new separate class `TextHighlighter`
that can be used with regular PDFs and XFA PDFs.
To mimic the current find functionality in XFA, two arrays
from the XFA rendering are created to get the text content
and map those to DOM nodes.
Fixes#13878
- All the scale factors in for the substitution font were wrong because of different glyph positions between Liberation and the other ones:
- regenerate all the factors
- Text may have polish chars for example and in this case the glyph widths were wrong:
- treat substitution font as a composite one
- add a map glyphIndex to unicode for Liberation in order to generate width array for cid font
- In order to better compute text fields size, use line height with no gaps (and consequently guessed height for text are slightly better in general).
- Fix default background color in fields.
- a rectangle can be defined after a field and so from a z-index pov, it's on top of the field, which means that the rectangle avoid to have some mouse events in the fields;
- so this patch just disable pointer events for all elements under svg (included).
- font line height is taken into account by acrobat when it isn't with masterpdfeditor: I extracted a font from a pdf, modified some ascent/descent properties thanks to ttx and the reinjected the font in the pdf: only Acrobat is taken it into account. So in this patch, line heights for some substituted fonts are added.
- it seems that Acrobat is using a line height of 1.2 when the line height in the font is not enough (it's the only way I found to fix correctly bug 1718741).
- don't use flex in wrapper container (which was causing an horizontal overflow in the above bug).
- consequently, the above fixes introduced a lot of small regressions, so in order to see real improvements on reftests, I fixed the regressions in this patch:
- replace margin by padding in some case where padding is a part of a container dimensions;
- remove some flex display: some containers are wrongly sized when rendered;
- set letter-spacing to 0.01px: it helps to be sure that text is not broken because of not enough width in Firefox.
- Fix a typo in order to open the pdf in issue #13679
- After fixing the fill default color there wer some regressions because of z-index
and when fixing z-index there were some regressions because of borders
- So fix the borders rendering.
- support paragraph margins, line height, letter spacing, ...
- compute missing dimensions from fields based almost on the dimensions of caption contents.
- it aims to fix#13583;
- fix the switch to breakBefore target;
- force the layout of an unsplittable element on an empty page;
- don't fail when there is horizontal overflow (except in lr-tb);
- handle correctly overflow in the same content area (bug 1717805, bug 1717668);
- fix a typo in radial gradient first argument.
- when the CSS line-height property is set to 'normal' then the value depends of the user agent. So use a line height based on the font itself and if for any reasons this value is not available use 1.2 as default.
- it's a partial fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1717681.
This extends the approach in PRs 12848 and 13606 to also apply to the `xfaLayer`, since otherwise XFA forms will be similarly broken in most non-default scroll/spread modes.
- a checkbox or radio doesn't have to be rescaled when the container is large so give the extra space to the caption to avoid some word wrapping.
- when the caption is on the right, then put ui on the left as first element and so remove flex:row-reverse stuff.
- some elements weren't displayed because their rotation angle was not taken into account;
- fix box model (XFA concept):
- remove use of outline;
- position correctly border which isn't part of box dimensions;
- fix margins issues (see issue #13474).
- move border on button instead of having it on wrapping div;
- I thought it was possible to rely on browser layout engine to handle layout stuff but it isn't possible
- mainly because when a contentArea overflows, we must continue to layout in the next contentArea
- when no more contentArea is available then we must go to the next page...
- we must handle breakBefore and breakAfter which allows to "break" the layout to go to the next container
- Sometimes some containers don't provide their dimensions so we must compute them in order to know where to put
them in their parents but to compute those dimensions we need to layout the container itself...
- See top of file layout.js for more explanations about layout.
- fix few bugs in other places I met during my work on layout.
- implement few positioning properties: position, width, height, anchor;
- implement font element;
- implement fill element (used by font) and its children (linear, radial, ...);
- font property is inherited from ancestor container (see https://www.pdfa.org/wp-content/uploads/2020/07/XFA-3_3.pdf#page=43) so let CSS handles that stuff;
- in order to reduce the number of properties to set, only set non default properties and put the default in CSS;
- set a background to some containers to be able to see them (will be removed in a future commit).
- add an option to enable XFA rendering if any;
- for now, let the canvas layer: it could be useful to implement XFAF forms (embedded pdf in xml stream for the background and xfa form for the foreground);
- ui elements in template DOM are pretty close to their html counterpart so we generate a fake html DOM from template one:
- it makes easier to translate template properties to html ones;
- it makes faster the creation of the html element in the main thread.
