It works correctly with -strip, it does not work with +profile "8bim". But you are right, it seems to be a Photoshop related issue. It works perfectly with GIMP. I will do some further investigations.

Here is the download link for the colour profile:

> Is this an sRGB profile, or RGB?

sRGB IEC61966-2-1 with BPC

> You link to png files, not a tiff.

You have to click on the images to get into the detail view and then to click on the download button. Else you get the preview images (are png).

I have problems converting tiff files with layers from CMYK to RGB. The generated images have fancy colours in Photoshop (colours look OK in IrfanView). After merging the layers the colour conversion works perfectly, but I don’t want to lose the layers. I assume there is something going wrong with t...

Thank you very much for the tip.

I think "convert tiff_jpeg_compressed.tif out.jpg" does not change the colour space. It should change the format from tiff to jpeg. But in the resulting jpeg the black channel is missing completely. Screenshot from the TIFF: https://dl.dropboxusercontent.com/u/1973423/tiff.jpg Screenshot f...

Converting a TIFF CMYK image with JPEG compression to a JPEG corrupts colours. I tested with newest available version.

For example: convert tiff_jpeg_compressed.tif out.jpg

I have problems converting tiff files to jpeg or any other format. The tiffs have transparency and after converting the images show strange colours. I used the convert command: convert tiff-test.tif out.jpg Here is a sample file: https://www.dropbox.com/s/r0szsducaj9zd6t/tiff-test.tif Can you have a...

I don't know what that mean. But the conversion worked well in older versions (like 6.7.3). However in 6.7.3 the conversion failed for images in CMYK colorspace. Now the conversion works fine with the CMYK colorspace, but not with the RGB colorspace.

Resizing the tiff cmyk files works now. But now resizing the tiff rgb files corrupts the colors.

Tested using ImageMagick 6.7.6-5 2012-04-04 Q16

I found a problem resizing tiff / cmyk files. For example: convert test.tif -resize 200x200 out.tif. The colors are inverted and the black channel gets lost.

I upgraded from ImageMagick 6.7.3-7 to the newest release and encountered a problem converting pdf files to jpeg. There is something wrong with the pages sizes for example if the page size differs in a pdf. Here is a sample file: http://dl.dropbox.com/u/1973423/both.pdf. This conversion worked well ...

Here are the two files:
http://dl.dropbox.com/u/1973423/Stockholm_cmyk.tif
http://dl.dropbox.com/u/1973423/Stockholm_rgb.tif

Both files were created with Photoshop CS 5.5

I have several problems converting JPEG compressed TIFF files to JPEG files (ImageMagick 6.7.3-4 on Windows 7 64 Bit).

It's a simple conversion: convert xy.tif cy.jpg

RGB colorspace: convert crashes
CMYK colorspace: conversion works, but the colors are wrong

If you need I can post sample files.
