Commands of the form: produce a choppy image.

Image of the problem:


Code used to produce the image:

+antialiasing disables anti-aliasing. Try removing +antialiasing. See http://www.imagemagick.org/script/comma ... #antialias

That just makes the text look blurry. Bitmap fonts shouldn't need to be antialiased.

You have specified a very small size for that font, so small that some verticals are less than half a pixel thick. So if you anti-alias them the verticals are gray but visible. If you don't anti-alias, they are zero thickness.

Remedy: choose a different font or larger size.

The font still doesn't look right at a larger size , but I shouldn't need to set a large size anyway. Terminus-(TTF) looks fine in gimp at 12pt. I think that this is a bug in ImageMagick. On the project page for Terminus TTF (https://files.ax86.net/terminus-ttf/), it says:

There are applications that neither support the original Terminus Font nor use bitmaps embedded in TrueType fonts. They completely rely on the automatically generated scalable outlines.

Another bitmap font I tried had the same problem. Maybe ImageMagick lacks support for bitmaps inside TTF fonts?

Did you remove +antialiasing as I suggested above?

IM doesn't directly handle fonts, but uses the freetype library.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ http://www.imagemagick.org/download/beta/ by sometime tomorrow.

Not sure if it was resolved from a fontconfig update or an ImageMagick update, but it works perfectly now. Thanks!
