Status: RESOLVED DUPLICATE of bug 134708

(Core :: SVG, defect)

The transparence should be transparent, and not rendered in white. 
The transparent zones of the svg image should be rendered in the color of the background 
of the HTML page (or the background color of its container). 
 
But the container of the svg image (a div tag for exemple) could have something else than 
just a background color. Its style could be something like this: 
background: #78D url(image.png) repeat top left; 
 
So to resume the SVG images should react with an alpha chanel like PNG images, for their 
transparence! 
 

Reproducible: Always

Steps to Reproduce:
1. Just put only a circle in the middle of your SVG file. 
2. Put a background to your web page. 
 
Actual Results:  
Then you see the white color arround the circle and not the background color of the web 
page. 
 

Expected Results:  
No white instead of transparence. 

Sodipodi's export to PNG keeps the transparence of the SVG documents in the alpha chanel 
of the PNG files.
