Apply tvg Array instead of std::vector
Also Fixed to compList in update() to passed by reference, not copying.
Also Fixed Composition Target memory leak
Here is the binary size result:
[libthorvg.so] 1785376 >> 1607416
[text] 121255 >> 118277
[data] 7792 >> 7736
[dec] 129119 >> 126085
This Array is promoted from SvgVector to use it widely in tvg.
It's similar with std::vector, we can use it instead of it.
Also, svg_loader replaced with it subsequently.
* common Picture : Introduce Picture's size setter, getter APIs
If picture or file loaded by picture has an explicit Size(width, height),
it is transformed to fit the size.
Existing parser functions always return true.
Parser function's return value was not being properly used.
So, add a return to check whether it is parsed or not.
Add RawLoader class that loads and display raw images,
and adds a Rasterizer for image data.
Image data can be loaded via picture.
Loaded image supports Composition, Transformation and Alpha blending.
New API
Result load(uint32_t* data, uint32_t width, uint32_t height, bool isCopy) noexcept;
we introduced shared memory pool for avoiding reallocate memory
while it process the stroke outlines, It experimentally increase
the outline data if we use the allocated memory for multiples shape strokes,
we don't need to alloc/free memory during the process.
This shared outline memory is allocated for threads count
so that we don't interrupt memory access during the tasks.
@Issues: 75
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>
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 both <defs> and <svg> gradients are declared,
the update of gradient declared in <svg> is omitted.
Therefore, this patch fixes any missing gradient updates.
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.
Mask and clippath TAG are not supported yet.
If this TAG is used, the Child TAG declared with this TAG may cause problems.
To prevent that, declare them as Unknown types until they are supported. (display=none)
