ImageMagick includes the ImageToHBITMAP() method but not a HBITMAPtoImage() method. If you want to write this method and contribute it to ImageMagick for distribution, just post it here and announce you are releasing it under the ImageMagick license.

We can reproduce the error you are getting and will patch ImageMagick to hopefully read you image in the future. Unfortunately it may take some time to fix since AVI (and PSD) is a difficult image format to support.

The ImageMagick PSD reader has a number of bugs that we are addressing as time permits. In the mean-time you may need to use some other program (such as Gimp) to convert your image.

In ImageMagick 6.2.6-7 Beta we added a new log statement to display the actual command line being passed to the convert program to make debugging situations like yours easier. All you need to do is add -debug configure to the command line to get this information (and of course use ImageMagick 6.2.6 ...

Scale() introduces new colors so the image is no longer monochrome, a requirement for Group4 compression. Instead, use Sample() which does not introduce new colors.

The debugging output tells us that the convert program is getting something other than the command line you sent it. Its getting an 'x' and '1200'. You'll need to determine why that is being passed to the convert program.

A return code from the convert program of zero means success, anything else is an error. Make sure the return code is coming from the convert program. Try adding -debug all to see if any exceptions are thrown.

You have a few mistakes in your code. When you call MagickGetImageBlob() you need to specify an image format and depth so instead of unsigned char * data = MagickGetImageBlob(magick_wand,&length); you want MagickSetImageDepth(magick_wand,8); MagickSetImageFormat(magick_wand,"RGB"); data ...

The problem is most likely in the way your shell is interpretting the command line which can be compounded if the shell is being called from a scripting language like PHP. Next up we'll need to know if your calling from a scripting language or a shell. Which shell are you using? Which operating ...

The CMYK JPEG images created by ImageMagick are fine. They follow the JPEG standard. However, Adobe decided to invert the JPEG data in its files so some viewers follow the Adobe standard and others follow the JPEG specification. We try to follow the specifications as much as possible. To fix the ...

Seems to work for us with ImageMagick-6.2.6-6. We get a black channal that is all zero pixels with this command: convert -colorspace cmyk test.pdf -channel Black -separate test_black.bmp Now all zero pixels may not be what you want but that is what Ghostscript is giving us. As we suggested earlier ...

Try escaping the quotes by preceeding the quotes with a backslash.

We can reproduce the problem you posted and should have a fix within the next few days. Thanks for the problem report.

Looks like you may have an older version of PerlMagick that does not support the Identify() method. Try use Image::Magick; my $image; my $x; $image = Image::Magick->new; $image->Read('logo'); $x = $image->Write('logo.jpg'); print $x; If that fails, PerlMagick may not be installed properly.
