Clips and masks require to implement some additional variables,
so the new node type has been introduced. Implementation of the usage
of these additional variables will be the subject of a separate
commit.
Introducing the gradient transform() apis and changing the grad
algorithms made it possible to apply the shape's transformation
before saving the tvg file, in case the shape (or its stroke)
has a fill.
The values in absolute units are calculated based on the pixel unit.
Till now the default value of 90dpi was used. Since CSS3 (now CSS4 is
the most recent) 1 inch equals to 96 pixels. The necessary constants
are introduces in this commit.
This reverts commit cd5116b053.
Ah this breaks the Stress example due to Picture::duplicate() is not available...
Need to consider and come back again.
* common: added colorSpace() function
This patch introduces colorSpace() function for SW and GL engine.
* infra: change LoadModule:read() into LoadModule:read(uint32_t colorspace)
This patch changes LoadModule:read() into LoadModule:read(uint32_t colorspace)
* picture: implement passing colorspace into loader
This patch implements passing colorspace into loaders.
Loader->read is now called on the first update.
* external_jpg_loader: support colorspaces
* external_png_loader: support colorspaces
removed invalid nullptr checks.
New allocation doesn't gurantee that returns nullptr when it's failed.
It's useless on the modern compliers and our policy respects it.
The final gradient transformation depends on the coordinate system.
It can not be applied during an svg loading. The transformation matrix
has to be passed via api for further gradient processing.
Adds an alternative static jpg loader.
The jpg loader copied the jpeg decoding implementation from this open-source
repo: https://github.com/richgel999/jpeg-compressor
That opensource has the public-domain license, it doesn't have any restriction
of the copy.
note: jpgd.cpp is modified version (changed decompress_jpeg_image_from_stream)
for returning BGRA
meson's find_library() throws an error when the package cannot be found.
png static library is added, so it should be passed when package is not found.
Therefore, delete unnecessary find_library.
Copied only necessary decoding functions from the lodepng opensource.
See: https://lodev.org/lodepng/
additional changes:
- disabled crc for the optimal size.
- converted the format bgr -> rgb for our png example.
Still we don't have a concrete idea for the image formats,
We should fix the converting methods between bgra <-> rgba.
@Issue: https://github.com/Samsung/thorvg/issues/594
1.
Remove macro function. The existing macro function
was doing meaningless nested `return false`.
2.
Extract the logic to find the type as a function.
3.
The SimpleXMLType::Error case is not actually used,
and in case of invalid XML, Do 'return false' immediately.
