This utility method allows access to a specific paint instance
by its unique identifier.
Experimental API:
- const Paint* Picture::paint(uint32_t id)
- const Tvg_Paint* tvg_picture_get_paint(Tvg_Paint* paint, uint32_t id)
Lighten is applied, where multiple masks intersect,
the highest transparency value is used.
Darken is applied, where multiple masks intersect,
the lowest transparency value is used.
Experimental API:
- CompositeMethod::LightenMask
- CompositeMethod::DarkenMask
issue: https://github.com/thorvg/thorvg/issues/2608
Adds the ability to load some composite glyphs and prevents an error when a composite glyph is used.
Implementation based on ttf glyf table documentation: https://learn.microsoft.com/en-us/typography/opentype/spec/glyf
There are still some missing features like scaling, parent glyph point based positioning etc. I think this is a topic for future work. Howerever, it looks like implemented features are enough for utf-8 latin subset in major fonts.
issue: #2599
- revised the transformation building logic.
- rectified to properly search "this" composition layers.
- rectified the linear interpolation implementation.
- added "pingpong" looping attributes.
More precisely, culling the render objects by
determining if the group has no renderable objects.
Additionally, check opacity to quickly return
in the rendering process.
LottieRenderPooler is designed to manages rendering
instances(paints) efficiently through a simple pooling
mechanism to resuse among the animations
This replaces the previous individusal paints implemenations
among solidfill, precomp vierport and pictures,
also fix a potential paints corruption problems.
This patch provides initial support for the text range selector. Full support will be added gradually in subsequent steps. This is the first step.
Text range selector with following properties:
1. Text Range Selector (Units)
2. Text Style
- Fill Color
- Fill Opacity
- Stroke Color
- Stroke Width
- Stroke Opacity
- Opacity
- Rotation
- Position
- Scale
comp pointer is used for checking if the header is ready.
It can be written in a worker thread and needs a critical
section on the reader side.
This also potentally improve the thread efficiency
from the segment() / marker() function calls.
loader->stack.pop() at line 3271 is called to remove
the defs node added to the stack due to nested graphics elements.
However, it is called in an inappropriate situation and the loader's node tree is damaged.
Fixes an error where the close tag is recognized as a `line` of the graphics tag when it is `linearGradient`.
ex)
```
<defs id="def">
<linearGradient x1="1" y1="2" x2="3" y2="4" id="l"/>
</linearGradient>
<rect x="10" y="10" width="10" height="10" fill="blue" id="r2"/>
</defs>
```

Previously, the Lottie builder didn't account for image asset sharing
among multiple layers. This update rectifies the situation.
