> i have gone through the "[PDFBOX-3000] Transparency Group issues"...
> and there are some issues in pdfs that i have attached...
> Every time showTransparencyGroup() method is called the current graphics is translated by (x*xScale and y*yScale) which i assume is wrong.
> I think when transparencyGroup comes in pattern stream, then current graphics should not changed. as well as when patterns are nested then no need to change the parent graphics.
> i tried to fix it. i have attached the patch...
