frame() still returns a regular RGB Bitmap (now lazily converted
from internal CMYK data), but JPEGImageDecoderPlugin now also
implements cmyk_frame().
This is a simple container for 2d CMYK data.
This is a new class instead of a new format in Bitmap because:
* Almost all clients of Bitmap will want to deal with RGB data
* It keeps the ARGB32 typedef working
* Bitmap already does a lot of things
The idea is that a few select places will be able to use
CMYKBitmap and a color profile to do a better CMYK -> RGB conversion
than an image decoder could do, and then store the result in a Bitmap
for later display then.
CMYKBitmap misses some of Bitmap's features, such as shared
memory support, high-dpi scaling capability, etc.
Many sites load application/json and application/ld+json
content with script elements, so this debug line shows
up on a lot of sites and is not informative.
For every issue string, json['issues'][issue_string] contains a list
of (page, count_of_issue_on_this_page) tuples.
To get the total number the issue appears in the current document,
we need to add up all the count_of_issue_on_this_page, not multiply the
page number with count_of_issue_on_this_page and add those (－‸ლ)
The newer version installs a specific version of octokit, since the
latest version no longer supports the ruby installation in github
actions vms. This should resolve the CI issues.
On platinenmacher.tech there is a document without a window. During
size attribute parsing the window pointer is dereferenced which
causes a crash. This checks for the window to be actually there
before dereferencing.
As the spec points out:
> Note that a pair of keywords can be reordered while a combination of

> 50% left is not.
This was a bug in our implementation of alternative 2 of css-values-3,
resulting in the following CSS failing to be parsed:
`background-position: center right;`
This commit fixes the issue as part of an update of the parsing to
css-values-4. As far as I can tell, the grammar is equivalent - but
simpler to implement due to the lack of optional values.
The fix for this issue is also as part of alternative 2 parsing in the
new grammar.
Progress towards: #22401
Instead of serializing two calc() values to String and then comparing
those strings, we can now compare calc() values by actually traversing
their internal CalculationNode tree.
This makes style recomputation faster on pages with lots of calc()
values since it's now much cheaper to check whether a property with
some calc() value actually changed.
Previously, these were clipped by the RecordingPainter, which used the
path's bounding box (which in this case is zero width or height). The
fix is to expand the bounding box by the stroke width.
Fixes#22661
Note: This is unrelated to any recent LibGfx changes :^)
Some apps seem to generate malformed images that are accepted
by most readers. We now only throw if malformed data would lead to
a write outside the chunky buffer.
Includes a set of wav files of different frequencies, these are
each loaded and then written to a temporary file, checking that
the meta-data is correctly read and that the output matches the input.
Before this change, we used the wrong insertion point for flex items
in reverse layouts with `justify-content: normal`. This caused flex
items to overflow the flex containers "backwards" from the start edge.
This moves us a bit toward correctly representing two separate concepts
from the spec: lines and tracks. Lines divide the grid into tracks, so
there should always be a line concluding the last track.
Instead of assuming that the first font in the cascade font list will
have a glyph for space, we need to find it in the list taking into
account unicode ranges.
When the WebContent process has painted to its shared bitmaps, it sends
a synchronous IPC to the browser process to let the chrome paint. It is
synchronous to ensure the WC process doesn't paint onto the backing
bitmap again while it is being displayed.
However, this can cause a crash at exit if the browser process quits
while the WC process is waiting for a response to this IPC.
This patch makes the painting logic asynchronous by letting the browser
process broadcast when it has finished handling the paint IPC. The WC
process will not paint anything again until it receives that message. If
it had tried to repaint while waiting for that message, that paint will
be deferred until it arrives.
Some tags have a default value, we should return this value in
Metadata's getters when no value has been read from the input file.
Note that we don't support default values for tags with a count bigger
than one.
ExifOrientedBitmap was implemented before the introduction of the TIFF
decoder. So we had to provide a definition of the Orientation enum. Now
that we have a TIFF implementation that comes with some enum
definitions, we should prefer this source.
Process separation is a great way to prevent malicious users from
getting the GUI down with image files that make one of our decoder
crash.
It also makes life easier when developing image decoders.
If we know that the peer disconnected while receiving a message in the
generated code, let's shutdown the connection from here instead of
forcing each client to do so.
If no EventLoop is present in the stack (like when you forget to create
one), a message is nicer than letting the developer go through the
stacktrace to figure out what went wrong.
When using the BMP encoding, ICO images are expected to contain a 1-bit
mask for transparency. Regardless an alpha channel is already included
in the image, the mask is always required. As stated here[1], the
mask is used to provide shadow around the image.
Unfortunately, it seems that some encoder do not include that second
transparency mask. So let's read that mask only if some data is still
remaining after decoding the image.
The test case has been generated by truncating the 64 last bytes
(originally dedicated to the mask) from the `serenity.ico` file and
changing the declared size of the image in the ICO header. The size
value is stored at the offset 0x0E in the file and I changed the value
from 0x0468 to 0x0428.
