The gradients here look like something other than a linear or radial gradient, (though I haven't chased things down enough to say exactly which kind). If this is something like a coons mesh gradient, then it would be useful to have support for something like that (both in cairo and poppler). Separately, (and what should be a separate bug), it would be great to get poppler to start using cairo gradients for linear and radial gradients, (rather than doing piecemeal-geometry approximations as xpdf always did). -Carl (In reply to comment #1) > The gradients here look like something other than a linear or radial gradient, > (though I haven't chased things down enough to say exactly which kind).
