save as ... EPS gradients = bitmaps ???

Postby julo » Mon Nov 10, 2008 1:42 am

When I save my vector graphic in Inkscape as EPS file, gradients are change for bitmaps? Why? What can I do with this, when I want have only pure vectors?

Is this is the development version?

I haven't examined this feature but the reason is probably because gradient colours are defined as RGBA (where A is the alpha value for transparency). EPS doesn't support A which means you can't convert a gradient with transparency to an EPS, so Inkscape rasterises it. It would perhaps be an improvement if Inkscape detected the use of transparency and only converted to bitmap when its used. Illustrator will do the same whenever you use transparency (or other effects not supported by the EPS format) in a drawing.

Note that I don't KNOW this is the reason. It's just an assumption based on my understanding of the formats.

Thank you microUgly for your answer. I have newest version Inkscape 0.46. I didn´t use transparency. Is any free software for right convert from SVG to EPS withour bitmaps from gradients? Or is any other solution?
And what older versions of inkscape? Did they do it the same with gradients?

I think older versions of Inkscape won't export gradients at all. I'm not aware of a work around, sorry.

Thanks, microUgly.
I started with Inkscape and I was very glad with its. But I need use gradients and save graphics as eps file, too. Do you know about any software to convert svg file to eps correctly?
Or maybe another version of Inkscape enable save correctly eps file without transparency as pure vectors?

Huge improvement has been made in eps and pdf export in Inkscape since version 0.46. The current development version should export to eps without problems, gradients are exporetd as bitmap, you can choose the resolution for bitmaps.

prkos, I don´t know if you understand me. I need when I save my pure vector with gradients as EPS file so that I need pure vector without any bitmaps as pure vector always. No bitmaps. But Inkscape rasterize my gradients and I wont it.

Is any chance that this problem (gradients without transparency are converted to bitmaps in EPS files, too) will be solve in another version?

You could suggest this to the developers either via their mailing list or on the launchpad site.
