This "hack" was introduced to ignore the text-transform property for bookmarks.
Now that the whitespace management logic is done after the box creation (just
before building the bookmark label), we can do the same for the text
transformation (just after building the bookmark label).
Related to #607 and #137.
This early process enables properties with <content-list> values (string-set,
bookmark-label, etc.) to be defined using whitespace-processed strings.
Fix#607.
This solution is far from perfect. What we could do is to have a getter/setter
for the "text" attribute of TextBox using the "original_text" attribute, so
that we’re sure that we change one when we change the other.
But… That would be much more complicated and much slower, only to solve corner
use cases.
Of course, an issue will be open soon, when someone finds one of these cases ;).
Fix#137.
In CSS Display Module Level 3, the "display" property gets a long
representation allowing:
- a clear separation between inner and outer display type,
- new supported types (contents, run-in, flow-root…),
- inline list items.
This commit allows the (retrocompatible) new long syntax for "display". It also
supports the "flow-root" value. It doesn’t support values related to ruby, and
it doesn’t support the new "contents" and "run-in" display types.
This work gives the possibility to simplify the code in the block_*_layout
functions, and to improve the overall layout.
Related to #36.
Many operations, including page breaks, require a pointer to a specific
position of the box tree. For example, we used to have this structure to point
to the beginning of the first child of the second child:
(1, (2, None))
We now use:
{1: {2: None}}
This change is the first step to handle parallel flows (see #36). It doesn’t
change anything to the layout for now, but it allows us to store multiple
pointers in the same structure.
The next step is to handle multiple pointers in skip_stack during boxes layout.
It means that most of the *_layout() function need an extra for-loop to manage
multiple skip stacks.
We’ll then need to split new types of boxes: table cells, floats, absolutes…
The previous API wasn’t stateless, as it sometimes required to call
get_intrinsic_size before accessing intrinsic_ratio. The new API offers a
single method to get width, height and ratio.
Images were already embedded once when included in the same stream.
Unfortunately, patterns have their own streams, meaning that a pattern used
multiple times includes the image each time. That’s especially bad for
different boxes using the same background, as backgrounds are drawn as
patterns.
Fix#1414.
