Guarantee bitmap data after decoding has the expected length for
the given width+height+format. This eases the burden from backends
to worry about this. Pad or truncate the data if it doesn't have
the expected size.
The colors in a DefineBitsJPEG3 tag should be premultiplied alpha,
but in some SWFs they are incorrectly not premultiplied. Flash
Player clamps the color values to the alpha in this case to allow
these images to work more as expected.
Fixes#6893.
PNGs with 16-bit samples were not being normalized to 8-bit, screwing up their
appearance.
Add the `STRIP_16` transformation using `Transformations::normalize_to_color8()`,
which is equivalent to `Transformations::EXPAND | Transformations::STRIP_16`.
Also warn in case `png` outputs a color type other than `Rgb` and `Rgba`.
Due to the `EXPAND` transformation, this may be only `Grayscale` or
`GrayscaleAlpha`. `Indexed` is converted to either `Rgb` or `Rgba`.
Fixes#6662.
When decoding PNG/GIF data, convert the image to premultiplied
alpha so that it plays nicely with the renderer.
This applies to both dynamically loaded images and to PNG/GIF data
embedded inside a DefineBitsJPEG tag. This is in contrast to
DefineBitsLossless and DefineBitsJPEG tags w/ alpha, which are
already premultiplied in the SWF.
Also remove unnecessary clamps now that Rust defines casts as
saturating.
Fixes#6559.
This interface handles returning a bitmap given an ID and is used
by the render backend to get the bitmap used for a bitmap fill.
This will allow for bitmap fills in the drawing API, as these will
manage their own list of bitmaps.
This also removes the MovieLibrary dependency from render backends
and will allow for better decoupling in the future.
Matrices in an SWF file store their scale/skew components in
in 16.16 format (fbits).
Split `ruffle_core::Matrix` and `swf::Matrix`. `swf::Matrix` now
stores its data as `Fixed16` instead of immediately converting to
`f32`.
* #[derive(Collect)] should be before #[collect]
* Replace redunant `&buf[..]` with `buf`
* Changes most cases of UPPERCase to UpperCase
* Allow upper_case_acronym on most SWF types, as they are from
SWF spec/more annoying to change.
Pass the movie library to `register_shape` methods so that bitmap
charcter IDs can be resolved immediately on the proper SWF.
This fixes#2037, which cause incorrect bitmaps to be used when
multiple movies were loaded.
Change the usage of the stencil buffer to avoid running out of
stencil bits when too many nested masks are active.
This also cleans things up on wgpu which requires us to make
pipeline states in advice; now we only need a few stencil states
for masking as opposed to hundreds.
