Re: converting cmyk tif with background transparency to rgb tiff
OK I'd like to know if this work in your environment, because you said "it doesn't work" without any quote. see http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=28259&start=15#p125405 I did not say that worked. I only said that can strip xmp metadata. There is no PSD...

Re: converting cmyk tif with background transparency to rgb tiff
My point is that only PS shows the transparency. That is a problem, if other viewers including IM do not show the transparency. That is why this is an IM bug. I know there exists such tif. But I don't think it can be said it is definitely IM bug at least for display. Because it is not a tiff standa...

Re: possible bug extracting the transparency from CMYK TIFF
Try convert Original.tif image.miff display image.miff The second image is transparent. Is that what you are looking for? Surprised this works. (display image.miff[1] shows background transparent image.) But then, why identify -quiet Original.tif[1] doesn't work? (no output) Or > convert -quiet Ori...

Re: converting cmyk tif with background transparency to rgb tiff
should I go back to approaching it this way? it did produce the desired result convert Original.tif -alpha off /Users/tewellman/profiles/sRGB.icc -alpha on rgbout6.tif That does not work for me. If I open that in PS, the colors are wrong. And in the other viewers, the transparency is gone Transpare...

Re: converting cmyk tif with background transparency to rgb tiff
This command: convert Original.tif[0] +profile "xmp" -profile /Users/fred/images/profiles/sRGB.icc Original_rgb2.tif In other viewers besides PS, it has the right colors, but no transparency. In PS, it has transparency but has orange color where it should be brown. What I wrote (to get co...

Re: converting cmyk tif with background transparency to rgb tiff
As far as I tried only way to keep background transparency and keep the color during RGB conversion is: 1) convert tiff to psd with Photoshop or convert tiff to psd with ImageMagick and open in Photoshop and lock transparent pixels and save it. (About lock, related topic is here: http://www.imagemag...

Re: converting cmyk tif with background transparency to rgb tiff
This can be done with +profile tiff:37724, but background transparency (that is shown only in Photoshop) is lost.snibgo wrote: Perhaps the best solution is for an IM operation "-stripPhotoshop" or similar that removes all Photoshop metadata.

Re: Avoid a color in a jpg
It still can not be your help, but it seems there is one way to exclude specific color, according to the document. libjpeg9 has new -wipe option for jpegtran. A complementary lossless-wipe option is provided to discard (gray out) data inside a given image region while losslessly preserving what is o...

Re: Avoid a color in a jpg
I had thought so, and the other program would be mozjpeg. But it seems that's not true. What it guarantees is jpg to jpg conversion is lossless.snibgo wrote:Then perhaps another program can convert that without loss to JPEG.

Re: Pixel data changes with linux release
Short answer. 1. Now I have 2 libjepeg ... libjpeg62, libjpeg8. How is it decided which one is going to be used? As you are in Linux, ldd `which convert` shows library dependencies. But If convert (and other programs identify, compose etc) are statically linked, dependencies may not be shown. check ...

Re: Avoid a color in a jpg
If I understand right, if you can use lossless compression, pixel does not change. So it is worth to try mozjpeg for your 2nd time conversion. As far as I read, mozjpeg support lossless compression, and it try to keep compaitbility with jpeg. http://blarg.co.uk/blog/comparison-of-jpeg-lossless-compr...

Re: Tiff with layers boolean?
I noticed one minor limitation (even in MAC Byte Order). If you saved empty layer in Photoshop - one layer has some image and another is really blank, it still exists in Photoshop when reopened. But ImageMagick ignore it, "%[tiff:has-layers]" does not return true. However it happens also ...
