:-( the same doesn't work for me. and, the 'display' can only display one layer of the image too. what's the cause ? the original three layers in the image was got from the 'decomposite' command of GIMP.

thanks.

i have many xcf files each has sperated layers for each color ( r, g, b ). now, i run convert on them with a '-flatten' switch as below:

convert a.xcf -flatten b.jpg

but the result is not as expected, i only get a picture with one color.

when using version:

/usr/bin/convert -version Version: ImageMagick 6.0.7 02/20/06 Q16

this works for me under bash:

/usr/bin/convert -flatten -quality 95 $i ${i/xcf/jpg}

but in general, i use:

convert -version Version: ImageMagick 6.2.6 04/13/06 Q8

for some reason, the same command line didn't work anymore after I upgraded to 6.2.6, so as a quick work around, I use the old version 6.0.7 for flattening.

thank you. i have found the xcf2png and it works. the only question is how about if i want a xcf2tif? i think tiff is better than png, am i right? but since i don't familar with any of GIMP's script-Fu, i don't know how to modify the xcf2png.

ImageMagick simply doesn't implement all features of XCF since XCF is the native file format of GIMP and only GIMP supports it completely. If you want to flatten an XCF image or convert it to a different format, use GIMP for it.

If you need to do this from the command-line, there are a couple of XCF to PNG converter scripts using the GIMP batch mode. Try to google for xcf2png.

Hi,

As Sven mentioned there a couple of those scripts on the web: shell scripts with embedded script-fu, pure script-fu, etc. Which one are you using ?

If you use that one posted to http://www.gimptalk.com/forum/topic/Gimp-Xcf-Image-Viewer-2399-1.html

thanks, but the link seems not accessable from here. the core statement in my xcf2png is below:

( file-png-save 1 image drawable pngfile pngfile 0 9 0 0 0 0 0 )

so, to replace the above statement i think i have to unstand it first. it seems easy to guess that 'file-png-save' is a function and from the context i can guess the number '9' is the compression level.

to replace it, i think i need a function like file-tif-save or file-tiff-save. is there such a function? if so, what parameters i have to provide to it? before knowing of these information i think i can do nothing on it.

thanks!

near the bottom of the page it should be obvious where to replace "png" with "tif".

Regards,
Stephan.
