Your prefix should be /usr, not /usr/bin.

You could try posting a URL to your image here so we can reproduce the problem. Perhaps there is still a bug in the fuzz factor we overlooked.

The composite program has a -stereo option for creating stereo images.

Some of Anthony's examples rely on the very latest ImageMagick releases. The current release is ImageMagick 6.2.6-8. It should produce the expected results. If not, let us know.

In recent versions of ImageMagick we enhanced the fuzz factor to account for the alpha channel and in the process fixed a bug. So your command should work the same across ImageMagick versions but with a different fuzz value required for recent versions of ImageMagick.

Try this command to get good antialiased PDF or Postscript images:

• convert -density 400 logo.pdf -resize 25% logo.jpg

Add +repage after -trim to get the expected results.

Your image rendered for us, not sure if its the correct rendering though. We got a white canvas with a grey block near the bottom with a vertical green line half way through it. We're using ImageMagick 6.2.7 Beta built with the latest WMF delegate library.

We got:

• -> convert S144p008-pc.0089.tif S144p008-pc.0089.gif
  convert: S144p008-pc.0089.tif: unknown field with tag 37724 (0x935c) encountered. `TIFFReadDirectory'.
  -> echo $status
  0

So the convert program returned a 0 status as expected. We're using ImageMagick 6.2.6-8.

Add +matte to your command line to remove the alpha channel from an image.

We have a patch in ImageMagick 6.2.7 Beta to fix the problem you reported. The patch will be available within 48 hours.

You probably want to use this method from the MagickWand API: MagickGetImagePixels() extracts pixel data from an image and returns it to you. The method returns MagickTrue on success otherwise MagickFalse if an error is encountered. The data is returned as char, short int, int, long, float, or doubl...

• convert -list format

Look for the TTF format. Is the mode listed as r--? Does it also mention which version of Freetype was compiled with ImageMagick?

We tried your annotation with ImageMagick 6.2.6-8 and Freetype 2.1.7 and it worked properly.

Understood. Our conclusion is that ImageMagick 6.2.2 and below and ImageMagick 6.2.6-7 can read/write your monochrome TIFF image just fine. 6.2.6-7 has a problem writing it to PNG. ImageMagick 6.2.7 Beta can read/write monochrome TIFF and PNG without any problems.

We don't get a seg-fault with ImageMagick 6.2.6-8 but it does not render properly. ImageMagick 6.2.7 development can render it. 6.2.7 will be released in a few weeks.
