This PR adds resize ability to PixelPaint as per issue 11862.
The previous behaviour was to always rescale the canvas when
resizing an image. This adds a checkbox to toggle between
rescaling, and resizing which blits the existing canvas to
the top left of the new, resized canvas.
As part of this, a new ScalingMode is added to
LibGfx - None.
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.
We currently get a list of cookies when the Storage Inspector is opened
and never update that list when deleting cookies. This updates the
inspector to actually take cookies out of the model when deleting them,
rather than deleting a copy of them.
This adds player widget with working play/pause controls, a seek bar
which currently only displays the current playback position, and a
button to cycle between the scaling modes.
The player uses the new PlaybackManager class to handle demuxing,
decoding, and frame presentation timing.
Currently, the volume control is non-functional.
This moves the setting of code points in CICP structs to member
functions completely so that the code having to set these code points
can be much cleaner.
The class is virtual and has one subclass, SubsampledYUVFrame, which
is used by the VP9 decoder to return a single frame. The
output_to_bitmap(Bitmap&) function can be used to set pixels on an
existing bitmap of the correct size to the RGB values that
should be displayed. The to_bitmap() function will allocate a new bitmap
and fill it using output_to_bitmap.
This new class also implements bilinear scaling of the subsampled U and
V planes so that subsampled videos' colors will appear smoother.
This adds a struct called CodingIndependentCodePoints and related enums
that are used by video codecs to define its color space that frames
must be converted from when displaying a video.
Pre-multiplied matrices and lookup tables are stored to avoid most of
the floating point division and exponentiation in the conversion.
This effectively creates a double-buffer for tools to use when modifying
the layer's bitmap (content or mask). Once the changes have been made
the tool reports to the layer that it has made changes along with a Rect
of the changed region. The layer will then merge the changes from the
scratch image to the real bitmap. This merge is done as follows: If a
given pixel is inside the selected region, the pixel from the scratch
bitmap is copied to the real bitmap. If the pixel is not inside the
selected region, the pixel from the real bitmap is copied to the scratch
bitmap.
As an optimization, when there is no selection active, the new method
for getting the scratch bitmap will return the real bitmap and no
merging will need to take place.
For SystemServer, we simply ensure that the /dev mount is now mounted
with MS_NOREGULAR flag to ensure only non-regular files are created,
thus, achieving what DevTmpFS provided in its implementation, but in a
much more sane and clean way than how DevTmpFS did that.
For other userland applications, we simply make them being aware of this
flag so they can show an indication about this flag being used to the
user.
Adds actions to delete either a single cookie, or all of them.
This looks weird, because the GUI doesn't update until you "Inspect >
Open Storage Inspector", but it does function. :^)
To use the `GET /session/{id}/element/{id}/css/{property name}`
WebDriver endpoint, two new IPC calls through the Browser are
implemented:
- get_active_documents_type returns the type of the active document,
which is either "xml" or "html"
- get_computed_value_for_element returns the computed CSS value (as
String) for the given element and CSS property name
Polygonal selection tool allows for the drawing of any arbitrary
polygonal shape. It tracks clicked points in a vector, upon double
clicking we finalize the polygon and generate the selection mask. The
user can press the escape key during selection to cancel.
The mask is generated as follows:
- First we calculate the size of the bounding rect needed to hold the
polygon
- We add 2 pixels to height/width to allow us a 1 pixel border, the
polygon will be centered in this bitmap
- Draw the polygon into the bitmap via Gfx::Painter, making sure to
connect final polygon point to the first to ensure an enclosed shape
- Generate a selection mask the size of the bitmap, with all pixels
initially selected
- Perform a flood fill from (0,0) which is guaranteed to be outside the
polygon
- For every pixel reached by the flood fill, we clear the selected pixel
from the selection mask
- Finally we merge the selection mask like other selection tools.
This fixes a bug which shows up when a layer is offset and the selection
range includes pixels that are outside the current layer bitmap rect. We
would still try to delete that pixel from the bitmap since there was no
contains() check.
This extends the IPC calls `get_document_element` and
`query_selector_all` to be usable by the WebDriver. For this the
`WebDriverConnection` provides the same interfaces and takes care of
routing the data through the Browser.
Before this commit, when the wand select tool was used on a layer that
was moved, it would make the selection relative to the image, and not
relative to the layer. This commit fixes that issue.
This allows the WebDriver to create a cookie.
We use a Web::Cookie::ParsedCookie to transport the data through IPC
to take advantage of the RFC6265 Section 5.3 implementation in the
CookieJar.
