I am converting EPS files with a clipping path to PNG. The aim is to convert the clipping path to PNG transparency. Earlier I found in this forum a way to do so with two convert calls. No I found that these two calls are only working for RGB files. In CMYK I get a white (on some images a black ...

I am converting EPS files that have a SVG clipping path to transparent PNGs. The clipped region should be transparent in the resulting PNG. convert -density 299.99899291992x299.99899291992 40d7711576cd65e921c8c671f132acaf9a13732d.eps"[0] -resize 1566x4174 -alpha set -channel alpha -clip -negate /tmp ...

No clue where to get that kind of documentation. But the key part is, that imagemagick CAN read that path - just not write. So that should be possible to debug?

Is there any update on this? Is this accepted as a bug?

Hello again, my knowledge of C++ is very bad ... but I had a look at coders/ps3.c (is that used also for eps3) ? There is: /* PS clipping path from Photoshop clipping path. */ if ((image->read_mask != MagickFalse) || (LocaleNCompare("8BIM:",image->magick_filename,5) != 0)) (void) WriteBlobString ...

How can I detect the postscript level of an EPS file?

Hi, the clipping path is supposed to be around the black triangle in the picture. I have no idea as well how it is stored - but it can't be that proprietary or - if it is - it has been implemented in imagemagick, because identify can read it! $ identify -verbose dreieck_rgb_pfad2_photoshop.eps ...

@pipitas There IS a clipping path in JPG. No, to my knowledge, clipping paths are no part in the official JPEG file format specification. . interesting. At least photoshop can store it Yes, it is a proprietary extension of Photoshop. Only those applications which have reverse-engineered how it ...

I think I am not explaining the current situation clear enough. Your file is saved but I don't think it is saved in level 3. A co-worker of mine has illustrator which has an option to force the output format as level 3. The file now starts with 'PS-Adobe-3.1 EPSF-3.0' but ImageMagick is unable to ...

Did you find out how Photoshop is storing the clipping path different to ImageMagick? Can imagemagick store it the same way?

okay. did you find anything about the clipping path? Where it is different? How can I view the Postscript source of an EPS file? It looks compressed.

But it shows "ps:Level: Adobe-3.0 EPSF-3.0" - doesn't that mean level 3 ?

@pipitas There IS a clipping path in JPG. At least photoshop can store it and it is displayed when I do a identify -verbose. Also EPS files can have such a clipping path. Anyways, I am aware of the fact that other vectors are lost when converting with imagemagick. In our case the images are raster ...

Is anybody available to fix his on hire-basis. What would be the cost? You could send me an email to a.menk at imi.de

Can this be fixed?
