Hi, I'm trying the parse Shading elements in java, but I don't know how to get the alpha of colors.
I'm doing it like this
{code}
for (Element element = reader.next(); element != null; element = reader.next()) {
switch (element.getType()) {
case Element.e_shading: {
if (element.isOCVisible()) {
Shading shading = element.getShading();
if (shading.getType() == Shading.e_radial_shading) {
//Is there another/easier way than this to access shading colors ?
Obj funct_obj = shading.getSDFObj().findObj("Function");
Function function = new Function(funct_obj);
ArrayList<Color> gradientColors = new ArrayList<Color>();
if (function.getType() == Function.e_stitching) {
Obj bounds = function.getSDFObj().findObj("Bounds");
//Get ratios of the shading
ArrayList<Float> ratios = new ArrayList<Float>();
ratios.add(0f);
for (int i = 0; i < bounds.size(); i++) {
ratios.add((float) bounds.getAt(i).getNumber());
}
ratios.add(1f);
//Get shading color per ratio
for (float ratio : ratios) {
ColorPt colPt = shading.getColor(ratio);
switch (shading.getBaseColorSpace().getType()) {
case (ColorSpace.e_device_rgb): {
int red = (int) Math.round(colPt.get(0) * 255);
int green = (int) Math.round(colPt.get(1) * 255);
int blue = (int) Math.round(colPt.get(2) * 255);
gradientColors.add(new Color(red, green, blue));
// How can I get alpha of my stop color ?
}
}
}
}
}
}
}
}
}
{code}
Is it the proper way to parse gradients ? I didn't find anything on the web... What about other color spaces ?
How can I get the alpha of my colors ?
When I save my pdf into svg I can see that my colors have alphas
{code}
<stop offset="0.5744" style="stop-color:#130C0E;stop-opacity:0"/>
<stop offset="0.7977" style="stop-color:#130C0E;stop-opacity:0.6512"/>
<stop offset="1" style="stop-color:#130C0E;stop-opacity:0.95"/>
{code}
About ratios, I'm using "Bounds", but it only returns my 2 values "0.5744 and 0.7977" but in the svg I can see that there is also a third color with ratio "1". On another gradient I also saw "0" in the svg, that's why I manually add "0 and 1" but is it correct ... ?
Thanks for help
