`GL_INVALID_VALUE` is generate during `glGenBuffers` and is checked by
calling `glGetError()` inside `GL_CHECK` macro.
While the buffer id is valid if the value is not zero.
In every frame, the image undergoes a Colorspace conversion attempt.
This approach aims to bypass the step by retaining the pre-converted image data.
I acknowledge that this might not be the best approach,
but it is proving to be quite effective at the moment.
To achieve full threading efficiency,
the header should return the necessary properties:
view size, framerate, and duration.
This commit adds duration parsing.
Also don't do the header task in case of single thread
because there wouldn't be parallel effects.
1. convert mat4 directly from exist mat3, and remove unused calculation
code.
2. since normalized position is only meaningful in vertex shader stage.
use logical position in fragment shader stage for all gradient
pipeline.
Up until now, loading a clip composed of multiple
shapes worked correctly provided that they did not
undergo separate transformations. Now, such a case
has been handled.
Also the 'use' node inside the clip is supported.
Upgrade the used glsl version in GL shader source.
New version can directly specify the attribute location in
shader and the uniform block is only available in new glsl version
Loading images when the MIME type is incorrect is unnecessary
and often results in failure, adding unnecessary processing overhead.
Pictures should have a clear MIME type assigned by users.
VAO is new object in modern GL API, which can split and manage vertex
buffer and attribute state. This is optional in GLES and is mandatory in
GL.
Also index buffer is faster then pass cpu data in GL draw call.
- add an execeptional hanlding at parsing the assets.
- The precomp layer failed to prepare its instance in the parsing stage. This corrects the mistake.
The 3x3 matrix already contains the geometric transformation
information required for 2D rendering.
We can directly convert from the 3x3 matrix to
the 4x4 matrix to facilitate subsequent GPU rendering.
Added strDirname(), which returns the directory path name from the given string.
Added str2int(), which converts from the string to the integer.
These functions are used to supplement the existing string manipulation functions in the utils/str module.
- const uint32_t* Picture::data(uint32_t* w, uint32_t* h) const
Returning pixel data is not guaranteed as the picture may contain vector resources.
Remove it unless it's absolutely necessary.
@Issue: https://github.com/thorvg/thorvg/issues/1372
The custom implementations of 'strtof' and 'strndup'
present in the svg loader have been moved into a new
'utils' directory (strToFloat and strDuplicate, respectively).
