Opacity doesn't work in path objects #13

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Try to render this:
<svg width="176px" height="208px">
<path opacity="0.5" d="M0,0v67.696h176V0H0z 
M43.925,42.753c-6.324,0-11.451-4.924-11.451-10.998
    c0-6.074,5.127-10.998,11.451-10.998s11.451,4.924,11.451,10.998C55.376,37.829,50.25,42.753,43.925,42.753z"/>
</svg>

What is the expected output? What do you see instead?
expected:A black rectangle with 50% opacity with a fully opaque oval
actual: the rectangle is fully opaque (no transparency at all)

What version of the product are you using? On what operating system?
most recent

Please provide any additional information below.

I solved it by adding:

Float opacity = atts.getFloat("opacity");
if (opacity == null) {
paint.setAlpha(255);
} else {
paint.setAlpha((int) (255 * opacity));
}

at the last "else-if" statemint in doFill()

your patch helps me to achieve transparency. But I have to manually edit the 
document because do not receive the data.

this is an example of the default document:

<g opacity="0.65">
    <g>
        <path fill="#FFFFFF" d="....LARGE AMOUNT OF NUMBERS HERE..."/>
</g>
</g>

Modified manually to:

<g opacity="0.65">
    <g>
        <path opacity="0.65" fill="#FFFFFF" d="....LARGE AMOUNT OF NUMBERS HERE..."/>
</g>
</g>
Iḿ looking how can work without modify the file

I search some info of svg and I look that <g> == group, before that i dont 
understand wath are <g>, XD 
I make some basic changes on the process how the opacity are made, I added a 
counter for the levels of <g>, copy the same mechanism of the levels of 
display="none"; at the moments this patch rules for my needs but I see the 
overlay of opacity more "pure color" than on illustrator.

Sorry for my english; but the only important here is the code XD.
