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.
Changes:
1. New shape->duplicate(Shape) api.
2. New example: testDuplicate
3. Added capi binding for duploicate api
4. Added capi duplication test in testCapi.c
Description:
Added implementation of duplicate api. For now it supports stroke
properties and shape properties (fill color, path) duplication.
TODO:
Implement gradient properties duplication
put missing const parameter and correct set/get naming.
attention, these two apis are changed!
tvg_gradient_color_stops() => tvg_gradient_set_color_stops()
tvg_gradient_spread() = tvg_gradient_set_spread()
* 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.
warning: absolute value function 'fabsf' given an argument of type 'double' but has parameter of type 'float' which may cause truncation of value [-Wabsolute-value]
When both <defs> and <svg> gradients are declared,
the update of gradient declared in <svg> is omitted.
Therefore, this patch fixes any missing gradient updates.
When there is a matrix of linear gradient, the applied formula is this.
= T(x - cx, y - cy) x g->transform x T(cx, cy)
This patch has modified this formula to work properly.
In relation to the declaration of rx and ry attribute of rect, the following three cases occur.
rx="10" (or ry="10"
rx="10" ry = "0" (or rx="0" ry = "10")
rx="10" ry = "10"
To cover these case, we check the rx and ry declarations.
tvg canvas must draw retained shapes for every draw call
even though user missed call update() for shapes.
that case canvs must draw shapes without update,
it means drawing them within previous condition.
