Post any defects you find in the released or beta versions of the ImageMagick software here. Include the ImageMagick version, OS, and any command-line required to reproduce the problem. Got a patch for a bug? Post it here.
We do not support a 3g format but we do support g3. The g3 format is a fixed width of 1728 as required by the standard. You can improve the appearance of the fax with the density option:
convert -density 200 resume.pdf g3:im.fax
Given this clarification, what exactly is the bug this user is concerned about?
Once again there is no 3g format. If you use 3g:resume.002 ImageMagick will create a file on disk called '3g:resume.002' in the PDF format since the original image is in the PDF format. If you use g3:resume.002 it creates a perfectly usable file called resume.002 in the G3 fax format. You can display the resume.002 file that the user included in the bug report like this:
display g3:resume.002
It displays fine for us. Given this discussion, can you let us know where the bug is. So far ImageMagick appears to be behaving as expected.
