This reverts commit 74b27c74af.
This patch breaks Stroke example. 1 line drawings...
There is a possibility that less 1 (i.e: 0.5) width axis-aligned line drawings...
So logically "&&" is correct.
The alpha value calculation pulled out outside the inner loop
to reduce the number of unnecessary operations.
Added local variables to reduce the number of costly
multiplications performed in a loop.
There transformation logic was not identical between shape & gradient
gradient transform was applied into center of gradient world,
while shape wasn't. So... we correct gradient transform metric to shape like.
@Issues: 255
Description:
Crash was observed in examples when composite object was used.
It was caused because __m256i object was used on non aligned
memory to 32bit. Algorithm in this function was changed to use
unaligned __m256i_u object. Code was also simplified.
* sw_engine: adding a gradient as a stroke feature
Similarly as a shape may have a gradient fill so can the stroke.
* Capi: adding APIs for a gradient stroke

added a routine that draw non-transformed translucent image.
composition images will use this routine to draw faster.
Also added optimization point comments in raster image.
Renamed internal interfaces.
We need both blender & compositor interfaces.
Renamed SwCompositor -> SwBlender which is for pixel joining methods.
Added (SwCompositor, Compositor) which is designed for compositing images.
Splited out ClipPath routine from other pixel compositions'
since yet it's unlikely compatible...
Also revise internal engine interfaces to be simpler.
This is a step forward to enhance masking feature.
The wasm is using the ThorVG output starting whith "SVG:" to show
unsupported element and attribute of svg file.
This patch updates wasm_build.sh to make ThorVG prints log,
and removes build errors.
- Following commit needs to include 'algorithm'
1ed6113 common sw_engine: code refactoring & stabilizing.
- Following commit needs to include 'string'
5481633 svg_loader XmlParser: Print unsupported elements, ...
Introduce RendererMethod::renderRegion() to return acutal drawing region info.
That is used by scene composition to composite actual partial drawing region
for better performance.
@Issues: 173
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 is an additional enhancement of af8c278c5e
Now scene opacity composition is supported.
Also, this implementaion fixes an incorrect scene bounding box computation.
Plus, adding stroking feathering to shape bounding box size.
Move the prepare stage of shape & stroking composition stage to a separate function
this returns SwImage to use in composite stage.
Also clear partial region buffer since we know composition area.
There is 1 pixel misaligned issue observed.
Found out transform() increases 0.5 pt always.
This transform() logic was broken by this change - e00f948705
and now recorvered to origin.
