I need to generate low resolution black and white images of texts in ImageMagick. These images will be plotted in a small LED matrix. The text need to have 7 pixels of height.

For now, I'm using:

```
convert -negate -threshold 15% -font Courier -size 80x11 caption:'hello' out.bmp

```

Output image:

Even with the height being more than I need, due to low resolution and anti-aliasing correction, the letters are not pretty and symmetric. Has anyone did this and can help me out?
