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.
This patch has 2 purposes,
1. revise the loaders infrastructure to support both static/external linking loaders.
2. add a template for static jpg/png loaders after external jpg/png.
Our default loaders prefer static linking, external loaders are only available
when dependent libraries on the build system are found.
You might wonder why we have the external loaders together,
they might be faster than static loaders since the popular libraries are likely to be well maintained,
fine-grained optimized.
Thus in this patch, meson tries to apply the external loaders first
then see if the dependencies were found or not,
if it's failed, it turns to the default static loaders.
Next this patch, we need the contribution for actual static jpg/png loaders implementation.
@Issue: https://github.com/Samsung/thorvg/issues/594
"runtime error: load of misaligned address 0x7fb67895c815 for type 'unsigned int', which requires 4 byte alignment"
This is actually not an issue but we can resolve it with an easy workaround,
since we don't need to see this report repeatedly.
Current paint::bounds() returns the coordinates under the raw status,
the values are not quite useful if the paint object has the transformed children.
Thus, we extends the feature and give an additional parameter "transformed"
to return the coordinates values after transformation by user demands.
This is also necessary for tvg format, since we need the exact view size of the scene information.
The previous api is deprecated and we introduce a new api to replace it.
@APIs:
+ Result Paint::bounds(float* x, float* y, float* w, float* h, bool transformed) const noexcept;
- Result Paint::bounds(float* x, float* y, float* w, float* h) const noexcept;
@Issues: https://github.com/Samsung/thorvg/issues/746
Since the arc flags can have values 0 or 1, we reported as
an error cases, when a float value was given.
Since the EBNF grammar can be used, we misread some paths.
Removing the condition that prevents giving a float as a flag solves
this problem and is in agreement with the w3 specs.
