Painter always has a target bitmap, so let's return a reference.
(cherry picked from commit f42c18bc4c4a5d49fccbfab996bf04d77476b366;
amended to resolve conflicts in Painter due to us having more APIs,
and to update code no longer in ladybird: DisplayListPlayerCPU, and
Magnifier and ThemeEditor)
This will allow users to avoid including Painter.h
(cherry picked from commit 254d040ff4f81a0e04364d5d29a25c98d580cbb5;
amended to fix conflict in Painter.cpp because we didn't remove the
scale concept, and to keep a forwarding enum in place until we've
converted the rest of our code.)
To rebaseline image test expecatations, I ran:
out/gn/Ladybird.app/Contents/MacOS/headless-browser \
--resources $PWD/out/gn/Ladybird.app/Contents/Resources \
--dump-failed-ref-tests \
--run-tests $PWD/Tests/LibWeb \
--filter 'canvas-*'
I then copied over the new baselines with
D=Tests/LibWeb/Ref/reference/images
cp test-dumps/canvas-implict-moves-and-lines.png \
$D/canvas-implict-moves-and-lines-ref.png
(Note: No `-ref` suffix on first path, yes suffix on second path.)
We currently don't track if a path is open or closed, and paint
butt linecaps at the end of closed paths too. We did that with
round linecaps as well, but there that wasn't visible. This makes
closed paths look a bit weird now; we'll have to fix this in a
follow-up. In a way, this just exposes another not-yet-implemented
feature.
This reverts commit 59cb7994c6.
This change caused a bug where getImageData returned the image in
BGRA8888 format instead of RGBA8888.
(cherry picked from commit d2f9ba7db1d8dd1dd611e6a3f40b9125b5aa054d)
It is now possible to pass an optional `ImageDataSettings` object to
the `CanvasImageData.createImageData()` and
`CanvasImageData.getImageData()` methods.
Instead of copying the image data pixel-by-pixel, we can memcpy full
scanlines at a time.
This knocks a 4% item down to <1% in profiles of Another World JS.
A bunch of this is leftover from pre porting over to new AK::String.
For example, for functions which previously took a ByteString const&
now accepting a StringView.
This allows for:
* Transformed text (e.g. rotated text)
* Stroked text
* Filling/stroking text with PaintStyles (e.g. gradients)
* Squashed/condensed text (via maxWidth parameter)
Fixes part of #22817
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:
$ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \
Meta Ports Ladybird Tests Kernel)
$ perl -pie 's/\bDeprecatedString\b/ByteString/g;
s/deprecated_string/byte_string/g' $xs
$ clang-format --style=file -i \
$(git diff --name-only | grep \.cpp\|\.h)
$ gn format $(git ls-files '*.gn' '*.gni')
With this change, we now have ~1200 CellAllocators across both LibJS and
LibWeb in a normal WebContent instance.
This gives us a minimum heap size of 4.7 MiB in the scenario where we
only have one cell allocated per type. Of course, in practice there will
be many more of each type, so the effective overhead is quite a bit
smaller than that in practice.
I left a few types unconverted to this mechanism because I got tired of
doing this. :^)
Stop worrying about tiny OOMs. Work towards #20449.
While going through these, I also changed the function signature in many
places where returning ThrowCompletionOr<T> is no longer necessary.
Add the CanvasTextDrawingStyles mixin with the textAlign and
textBaseline attributes. Update fill_text in CanvasRenderingContext2D
to move the text rect by the text align and text baseline attributes.
Wrote a simple HTML example to showcase the new features.
Works for fills and strokes (using colors, gradients, or patterns),
along with images.
fill_rect() has been updated to use fill_path(), which allows it to
easily transform the rect, and already supports opacity.

The transform can change between path building operations (and before
the path is filled or stroked). This fixes the sun ray backgroun on
the https://www.kevs3d.co.uk/dev/html5logo/ canvas demo.
This allows clipping your drawing by any path you like! To do this
all painting has been wrapped around a new draw_clipped() helper
method, which handles the clipping before/after painting.
Note: This clipping is currently missing support for intersecting
clip paths.
We now select between nearest neighbor and bilinear filtering when
scaling images in CRC2D.drawImage().
This patch also adds CRC2D.imageSmoothingQuality but it's ignored for
now as we don't have a bunch of different quality levels to map it to.
Work towards #17993 (Ruffle Flash Player)
Note that as of this commit, there aren't any such throwers, and the
call site in Heap::allocate will drop exceptions on the floor. This
commit only serves to change the declaration of the overrides, make sure
they return an empty value, and to propagate OOM errors frm their base
initialize invocations.
Having an alias function that only wraps another one is silly, and
keeping the more obvious name should flush out more uses of deprecated
strings.
No behavior change.
This needs to happen before prototype/constructor intitialization can be
made lazy. Otherwise, GC could run during the C++ constructor and try to
collect the object currently being created.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
