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.
previous implementation didn't consider multiple canvases,
multiple canvas shared one renderer engine that brought corrupted contexts.
Thus, each canvas instances should have designated renderer engine instances.
Now fixed.
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)
Reverted incorrectly modified code in 3b9bb51321.
The newly created node becomes a child of the parent parameter
and is deleted together when parsing ends.
If there is an empty (unused) <defs /> inside the svg file, this can cause problems.
<defs> node is managed separately in loader->def.
So it doesn't have to be added to loader's list.
