We have a patch in 6.2.6-4 Beta to correctly scale the RGB to CMYK color conversion. 6.2.6-4 is scheudled for release within a few days.

We thought that cloning in MagickCore might be best for the reasons you mentioned, but we choose not to because its quite expensive to modify a cloned image and you as the user could always clone the image yourself before calling WriteImage(). We clone in MagickWand because its a higher level API an...

Ok, only two possibilities. One you have more than one version of MagickWand on your system or the configure script is not set up proerly to detect MagickSetImageTicksPerSecond().

Image signatures are sensitive to the image depth, image colorspace, and whether the image has an active opacity channel or not. An image with image->matte set to False, for example, produces a different signature than one with image->matte set to True. Given the above could that account for the dif...

MagickSetImageTicksPerSecond() is a relatively new method(). If its not found it just means you need to upgrade your ImageMagick distribution. The current release is 6.2.6-3.

ImageMagick tries to determine what file format an image is in but can't always succeed. If the magic number does not confirm its format it tries to use the file extension (.ico means the image is in the ICO format). You can always force a format. For example, ico:image.dat tells ImageMagick the ima...

Use this command:

• convert srcimg.png -resize 264x png8:dstimg.png

Use the identify program to check for corrupt image files. Iterate thru all the files and check for a non-zero program exit status. A non-zero status means an exception occurred most likely due to a corrupt image.

To identify each image in the list you must iterate over the list. Something like:

The dashed line problem is a known bug and its on the list of things to fix. No time-line for a bug fix just yet.

You did not provide enough information to be helpful. Lets assume you mean you are not getting proper CMYK colors from an RGB image. If so, you need to use two color profiles. One defining the RGB colorspace and the other for CMYK, perhaps an sRGB and Swop color profile. You can engage these with th...

Try adding -strip to your command line to remove any image profiles from your image and we suspect your final thumbnail image will be at a reasonable size.

We will have a new Cygwin binary distribution within 48 hours. Thanks for alerting us to the problem.

By default, ImageMagick builds for the system directories in /usr/local which you do not have permission to write in. Instead, configure with the --disable-installed option. Add --disable-shared if you don't want to bother with shared libraries. If all else fails, you can try the Fedora pre-compiled...

PerlMagick-6.22 is part of the ImageMagick source distribution. Grab ImageMagick-6.2.2-5.tar.gz and unpack. You will find PerlMagick as ImageMagick-6.2.2/PerlMagick.
