Legacy ImageMagick Discussions Archive

Hello, guys!
First, I would like to thank you for developing so great product!

Here is the output of # convert -v:
Version: ImageMagick 6.5.3-10 2009-08-12 Q16 http://www.imagemagick.org

I try to convert a tiff image into a jpeg. During the process I get the following errors/warnings: I found a similar issue discussed here viewtopic.php?f=3&t=14397.
I tried this: but I still get the same errors.

In the end, the resulting jpeg image is rendered neither by Internet Explorer nor by Chrome. If I try to view the jpeg image with Picasa or default Windows Image Viewer, it show it correctly as if nothing is wrong.

Upgrading to ImageMagick 6.5.4-10 seems to be impossible due to system crashes when trying to get it all to work.

Here is the link to the tif file I am trying to convert:

Anybody encountered such an issue? Managed to solve it?

You can safely ignore the TIFF warnings. You TIFF image is in the CMYK colorspace. Some browsers do not support CMYK. Instead convert your image to RGB with -colorspace RGB. Its better to use profiles instead (e.g. -profile).

Thanks for your reply!
I tried to convert with RGB colorspace, and for some images it worked fine. But not for all. I do processing using system cron which runs a php script that converts 4 images at a time. It successfully converts two of them, and then it crashes creating a php.core file around the script. It says "Segmentation Fault". Some tif images are impossible to convert or what? What else can I do to make it work?

P.S. Didn't quite get it about -profile. What is this option for?

did you put the -colorspace before the input?

convert -colorspace rgb input output

see input settings at http://www.imagemagick.org/Usage/basics/#why


for profiles see http://www.imagemagick.org/Usage/formats/#profiles

I am no expert on these topics, but this is what you can find by searching the archives about such problems.

Yes, I used colorspace option before input file like this:
For some images it worked fine, but with others I get segmentation fault and core crash.
But I need to solve this problem very much.

You will need help from IM folks. but have you tried upgrading to the current version 6.5.6-1

your file sky.tif is very big (66MB). might you be running out of memory?

Another file that fails to be converted is 1.59Mb, so I am sure the problem is not in the file size.

Can you upgrade to the latest ImageMagick release, 6.5.6-1? If it crashes we would like to hear about it. If you know how to debug, a stack trace would be most helpful.

I also met this problem when I tried to convert some pictures with tif format. My convert version is : it was not the latest one. I couldn't convert my pictures to eps format and the error message were the same: And files couldn't be opened.It failed...

However, I found something interesting. When I tried to convert to png format, it gave the same error while the output seemed all right. Something weird!
With GIMP, it is all right.
