Hello Pol stra,
Off-topic for this mailing list, but on-topic for you: You can do this with Inkscape.
* Install Inkscape: http://inkscape.org/download/?lang=en * Open the EPS in Inkscape
Working white-on-white sucks, so * File > Document properties > click to the right of 'Background:', below the Default units dropdown * Choose something nice and pastel-coloured with alpha (opacity) set to non-zero.
* Select the object * Object > Ungroup (Ctrl+Shift+G) to make Inkscape see the individual paths, instead of a single EPS object The single rectangle selecting the object has now turned into a heap of rectangles. * With the colours at the bottom, set the fill to be red with click and/or set the stroke to be red with Shift+click
This will probably not have the desired effect because some of the constituent paths will have black fill+transparent stroke, and with others it will be the other way round. So you'll have to set fill/stroke individually.
* Select paths in turn, and set their fill/stroke as appropriate. Their respective values are shown in the bottom left. If you select multiple paths and their fill/stroke is different, it will be shown as "mixed"; when multiple paths' fills/strokes are not mixed they are identical, and you can change them all at once.
(Depending on ... file-related things ... you may need to use Path > Object to Path at some point, and possibly Path > Break Apart. But probably not.)
Good luck!

Thanks Sietse I already tried the inskape way, but it’s too much work if you have many files to proced. But your answer gave me the idea to use imegemagick, so I found this trick: convert -background none -density 300 -negate a1.EPS bbb.png I do not know why, but the same command with an EPS output gives me a white background so I had use a png file. The result is good enough for me. Thanks again
