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
When using <use> node, do atrribute copy.
At that time, when target(url) is polygon or polyline,
points array is not copied, causing a problem in output.
So, add missing array copy.
Supports case of using style attribute for defined <clipPath>.
In SVG, <clipPath> can be used as a "clipPath" attribute or a style "clip-path".
This patch only supports "clip-path" of style is declared.
The remaining features will be added later.
[Example SVG case]
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
viewBox="0 0 64 64" enable-background="new 0 0 64 64" xml:space="preserve">
<defs>
<clipPath id="clipPath">
<rect x="15" y="15" width="40" height="40" fill="#F00" />
<circle cx="20" cy="20" r="10" fill="#F00" />
</clipPath>
</defs>
<circle cx="25" cy="25" r="20"
style="fill: #0000ff; clip-path: url(#clipPath); " />
</svg>
Canvas::clear() introduces a new argument "free" that deterimes freeing the retained paints.
If free is true, Canvas won't delete the retained paints so that user keep paints valid.
In this scenario, user must have paints pointers, free them manually or push them again to the canvas.
This scenario is useful if user wants to re-organize paints order in the list or reuse them.
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
Removed check for gradient radius. Because of check, x and y values
was ignored when radius equals 0 and api was not usable
in integration with external libs which sets gradient center and
radius in separeted functions.
we should avoid code insertion during file dependencies,
such as #include "xxx.h" which has implementations.
This could increase binary size, we can avoid it as possible.
Current patch improves binary size like this:
From: file(2059008) = text(120360) data(8096) bss(80) dec(128536)
To : file(1921832) = text(118429) data(7872) bss(56) dec(126357)
More additional patches will come in to optmize binary size.
When path ends with 'z' or 'Z' command, if 'm' comes as next command,
the current point is incorrectly referenced.
Since 'Z', 'z' means to close the path,
so, Save point and reuse it when 'M' or 'm' is called.
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.
