Opacity in EPS

Postby Theo Moore » Mon Jun 09, 2008 6:42 am

Is there a way to get Inkscape to save your images which were designed using opacity options WITHOUT actual opacity, but keeping the same look?

For example, I can save the image as a JPEG, then convert it to EPS. The problem is that you of course lose the vectorized data. But is there a way to get the best of both worlds? Manually, you could always just redo the image with different colour shades to fake the opacity. But this would take a long time.

Illustrator does this with it's own formats by rasterising the areas that can't be properly described in EPS. Unfortunately Inkscape doesn't have this sort of smarts, so there is no way around it--not without manually rasterising objects in your drawing (Edit > Make bitmap copy).

I'm running up against the same problem... if it's an individual object, you can select it, go to the color picker and pick that object, thereby coloring itself with the "visible" color (meaning, taking into account the original object, it's transparency and the background) rather than the actual color. You then have to crank the opacity on that object back up to 100%, of course, but it works. Haven't come up with a good solution for gradients yet, but the same approach could be applied. Practical on a large scale? Not even vaguely :( but... I think a "color baking" feature like this would be a huge boost to productivity for people exporting to .eps and it seems like more and more people are doing that. While I haven't dabbled with the inkscape code previously, I'm trying to see how hard it would be to automate these steps to a keystroke or write a plugin for it or something like that.

I'd love a feature like this also. It seems like it could be quite difficult to code but would be incredibly useful.
