Hi-

I see that Inkscape will export to EPS. It does this by embedding an image object.

Two questions.

1) Is this normal for EPS? Or is it usually vector data?
2) How does one set the resolution of the exported image?

EPS is vector data, but does not support advanced features like transparency, opacity nor any filter effects (blur and the more complex preset Inkscape filter effects). Objects with those attributes are rendered to bitmap and embedded.

For filter effects it's the dpi setting in the export options dialog, for transparency/opacity fallback rendering you can't (AFAIK) - it seems to be based on Inkscape's 90dpi, or even a lower value (72dpi?), I am not sure.

Note that in current Inkscape versions any object with opacity < 100% (and even a hidden layer with opacity) triggers the bitmap fallback rendering (reported as bug #427226 and others).

Possibly the solution in “Printing pages with objects with opacity != 1.0 gives bad results” can prevent rasterizing the whole page, but might slightly change the output where a transparent stroke and fill overlap.

Must be related to theis.

I had no transparent items, but I did have a filter effect defined.

Ultimately, I had to remove gradients as well to get a pure vector export.

I assume this is a bug in the cairo renderrer.

Could be the same issue as reported in Bug #491590 in Inkscape: “EPS Level 3 export Rasterized” (Unclear to me where the error happens - in Inkscape's export preparation for calling Cairo functions or in Cairo itself).
