Hello!

I'm fairly new to inkscape and I already have a huge problem - I'm trying to draw a scheme for my seminar and it looks ok in inscape (.svg) but when I save it in .eps it goes all strange. Little blue circles which have no borders in svg misteriously get them in eps. These borders seem quite random and remain when I print the figure.
Svg file: http://imgh.us/adhezija.svg

Any ideas on what to do?

thanks,
c

Welcome to InkscapeForum!

Hhhm, I've looked at your file, and all the blue circles have a Stroke. Based on your description, this doesn't seem to fit. Because you said in your original SVG, there were no "borders" and in the EPS, the borders are random. So I'm not sure. Is it possible that you submitted the wrong file? Or otherwise, can you clarify the problem?

Thanks

Note: All your circles do have a black solid stroke (though it appears very small because the circles have been scaled down - themselves as well as the nested groups they are inside).

Underlying issue: PostScript does not support transparency (or reduced opacity) in fill or stroke colors

When converting your sample SVG file to EPS, several [1] of the small circles with the light-gray fill get rasterized into a bitmap image (because the fill color is not actually a solid gray part partially transparent black). This happens because PostScript does not support transparency for vector objects, and Inkscape tries keep to appearance of the EPS file as close as possible to the rendered SVG file on-canvas (see also here). Note that earlier versions of Inkscape (0.46) simply ignored the transparency and would have rendered the circles in full black in exported PostScript files.

Depending on your EPS viewer and printer, the edges of the embedded fallback images might be visible. OTOH the minimal stroke width for PostScript files to render seems to be larger then in Inkscape, causing the not-rasterized circles to have a larger visible stroke than those in the rasterized fallback images.

Try this:

1. select all circles with a partially transparent fill and change the fill color to a solid gray with A = 255 before exporting to EPS (see attached edited SVG file).
2. If you don't want the circles to have a black stroke, remove it (see lower example in the attached SVG file).

[1] What's odd with the circles in your original example: only some are rasterized, others appear to get automatically flattened (semi-transparent black fill converted into a solid gray equivalent) - I don't know why this happens, just that the result is the same with 0.47 (cairo 1.8.8), 0.48.1 (cairo 1.10.2) and a current build of the development branch (cairo 1.10.2))

~suv, you are simply brilliant!
I probably would have gotten further with my investigation, if I had the means to actually display an EPS file.

Thanks for fast answers, I wasn't able to answer till now. Sorry.

So, I saw that I had really tiny border, that I did'n see the first time. I removed it and everything was ok. I was obviously blind.

thanks for help, again:)
