We introduced separate opacity interface to adjust alpha value by paint.
This opacity will affect to whole paint image if paint is a group of paints.
Also, this opacity is to multipy with fill/stroke alpha values.
This means if the opacity is valid, the paint might deal with a composition step,
which is very expensive due to additional rendering step.
One tip is, if you want to toggle on/off for a certian paint,
you can set opacity to 255 or 0.
@API Additions:
Result Paint::opacity(uint8_t o) noexcept;
uint8_t Paint::opacity() const noexcept;
@Examples: examples/Opacity
@Issues: 94
It missed to update shape data if visilibity is changed from false to true by alpha.
Also, it needs to update engine shape data for every requests.
There scenario can be allowed,
1. update shape
2. change shape property
3. update shape
4. draw
previously engine could skip step 3, its result was not properly expected.
@fix #84
common sw_engine: Implement ClipPath feature
Paint object can composite by using composite API.
ClipPath composite is clipping by path unit of paint.
The following cases are supported.
Shape->composite(Shape);
Scene->composite(Shape);
Picture->composite(Shape);
Add enum
enum CompMethod { None = 0, ClipPath };
Add APIs
Result composite(std::unique_ptr<Paint> comp, CompMethod method) const noexcept;
* Example: Added testClipPath
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.
Introduce project skeleton such as build envrionment and interfaces
to build up code further cooperatively.
