certain systems, may not support file I/O operations.
ThorVG should provide users with an option to configure
builds according to their requirements.
This ensures that file I/O calls are avoided,
preventing potential crashes.
Please use the meson '-Dfile=true/false' option for this.
Please note that "THORVG_FILE_IO_SUPPORT" might be expected
for your thorvg manual build.
issue: https://github.com/thorvg/thorvg/issues/3008
The ThorVG OpenGL/ES engine has been stabilized and improved
significantly. Now, as a graphics engine, its drawing features
are quite functional. It is time to officially release the
engine and maintain it in the release process.
Thanks @Ruiwen for going above and beyond!

this commit introduces an additional build options:
- lottie expressions: this advanced feature in Lottie can
significantly increase binary size. Users now have the option
to enable or disable it based on their requirements.
Note that, this change introduces one config definitions:
- THORVG_LOTTIE_EXPRESSIONS_SUPPORT
Note that this change renames the Meson option from 'vector' to 'simd',
separates the NEON types into 'neon-arm' and 'neon-aarch',
and designates the 'mfpu' option solely for 'neon-arm'.
Some systems such as micro-processor might not support
the thread feature on the system.
Enhance the portability by compiling the thorvg with toggling the
threading depepdency through the build option.
For this, thorvg newly introduced the internal Key/ScopedLock abstraction
for transparent thread-locking dependnecy.
To turn off the thread feature, please use the next build option:
$meson setup build -Dthreads=false ...
Note that, the thread feature is enabled in default.
Turning off the thread feature could reduce the binary size by 7kb.

ttf is an industry standard format that is the most widely used
in the products. Now thorvg supports the basic features of
the font to supplement the text drawing.
The implementation is followed the ttf spec,
the covered features are:
- horizontal layouting with kerning.
- utf8 -> utf32 converted glyph drawing.
To use the feature, please enable ttf loader:
$meson -Dloaders="ttf_beta, ..."
@Issue: https://github.com/thorvg/thorvg/issues/969
Add save() API that takes tvg::Animation as a parameter.
This API uses gif.h to create each animation frame as a gif frame.
Gif creation do not support threads because they must be added sequentially.
Please see example/GifSaver.cpp
ex)
auto animation = tvg::Animation::gen();
auto picture = animation->picture();
picture->load(EXAMPLE_DIR"/walker.json");
auto saver = tvg::Saver::gen();
saver->save(std::move(animation), EXAMPLE_DIR"/test.gif");
saver->sync();
New API:
Result Saver::save(std::unique_ptr<Animation> animation, const std::string& path, uint32_t quality = 100, uint32_t fps = 0);

WebGPU is a Render Hardware Interface built on top of the various APIs
provided by the driver/OS depending on your platform.
WebGPU exposes an API for performing operations,
such as rendering and computation, on a Graphics Processing Unit.
WebGPU official documentation: https://www.w3.org/TR/webgpu/
The new engine type introduced: tvg::CanvasEngine::Wg
The new canvas type introduced: tvg::WgCanvas
Example:
$meson setup build -Dengines=wg_beta
`
// init engine webgpu
tvg::Initializer::init(tvg::CanvasEngine::Wg, 0);
// create wg canvas
auto canvasWg = tvg::WgCanvas::gen();
canvas_wg->target(glfwGetWin32Window(window), width, height);
// ...
// terminate engine and window
tvg::Initializer::term(tvg::CanvasEngine::Wg);
`
Still this feature is under the beta
Issue: https://github.com/thorvg/thorvg/issues/1479
Changes:
- Added 'neon' vector option in build system
- Introduced neon version of rasterRGBA32 API, which improves
speed of the funciton on ARM cpu's around ~35%
This is an utility to convert a file from svg to tvg
To use this, enable the feature by toggling in the meson option.
$meson build -Dtools="svg2tvg" ...
See also the usage:
Usage:
svg2tvg [SVG file]
Examples:
$ svg2tvg input.svg
tvg saver is a new module to export tvg files.
In this patch, it also contains the infrastructure of saver module
to expand other types of savers such as png, jpg, etc.
To save the tvg file from a paint, you can use the Saver feature, for example:
auto saver = tvg::Saver::gen();
saver->save(paint, "sample.tvg");
saver->sync();
Later, you can read the "sample.tvg" using Picture.
auto picture = tvg::Picture::gen();
picture->load("sample.tvg");
...
The behavior of the saver will work on sync/async based on the threading setting of the initializer.
Thus if you wish to have a benefit of it, you must call sync() after the save() in the proper delayed time.
Otherwise, you can call sync() immediately.
Note that, the asynchronous tasking is depent on the saver module implementation.
Also, you need to enable tvg saver/loader modules from meson option. (yet this feature is under the beta)
@API Addition:
Result Saver::save(std::unique_ptr<Paint> paint, const std::string& path) noexcept;
Result Saver::sync() noexcept;
@Examples: tvgSaver

This patch introduces a jpg loader.
For decoding the image, libjpeg-turbo library is used. Library was found to be
fast (SIMD instructions accelerated) and portable.
@issue: #517
Catch2 is a multi-paradigm test framework for C++.
It is primarily distributed as a single header file,
very easy and simple to adopt this to thorvg project.
This patch introduces catch2 infrastsructure and one prototype as a sample.
You can refer "testInitializer.cpp", how to add unit test!
while ignoring else files such as "catch2.hpp", "testMain.cpp"
Also, enable Unit-tests with meson option when you change any thorvg code.
$meson build -Dtests=true.
launch tvgUnitTest in the build result then verify 100% coverage
before submitting any patches.
tests is now officially placed in src/examples,
default is turned off, only necessaries turn it on.
ex) meson . build -Dexamples=true
+ this examples are required efl 'elementary' package.
* thorVG/example: added thorVG example app to convert svg to png
Rasterazing the svg file and extracting it as a png file.
The png encoder uses the 'lodepng' library.
(https://lodev.org/lodepng/)
Usage:
svg2png [svgFileName] [Resolution] [bgColor]
Examples:
$ svg2png input.svg
$ svg2png input.svg 200x200
$ svg2png input.svg 200x200 ff00ff
* ThorVG/Utils: Change examples to utils
* ThorVG/Utils: Move svg2png from util to src/bin
Renamed the build option for svg2png.
We don't include gl compile before it works properly.
For development & test please turn it on in meson_option.txt locally.
