Hello,

I want to render a grayscale series of tiff images from a colored pdf.

I type the following command:
C:\test_OCR>convert -type grayscale document.pdf document%d.tif

but it gives me totally white/blank images...

Any help would be greatly appreciated..

The command gives me proper grayscale, on IM 6.6.0-8 on Windows 7.

What version IM are you on? If old, an upgrade might do the trick. Otherwise, post a URL to a PDF that shows the problem.
