I wonder if it is possible to access the background color at the place
of a SVG graphic in nsSVGCairoCanvas.cpp.
The reason behind this is that due to the way the display APIs under
OS/2 work I need to "clear" the area that is going to be used for the
SVG display. Currently, I just fill it with white, but using the
background color of the <svg> (or the browser default if none is set)
would be nicer. For now I do this (snipped from the end of
nsSVGCairoCanvas::Init):
// clip to dirtyRect
cairo_new_path(mCR);
cairo_rectangle(mCR,
dirtyRect.x, dirtyRect.y, dirtyRect.width,
dirtyRect.height);
cairo_clip(mCR);
cairo_new_path(mCR);
#ifdef XP_OS2
cairo_set_source_rgb(mCR, 1, 1, 1);
cairo_rectangle(mCR, dirtyRect.x, dirtyRect.y, dirtyRect.width,
dirtyRect.height);
cairo_fill(mCR);
#endif
return NS_OK;
We still hope that there is a way to solve this problem inside the cairo
port but for now this is the best bet...
