DESCRIPTION

im_text(3) makes an image containing the text string rendered as a bitmap with Pango. The result is a one band 8 bit image with 0 - 255 as black to white. The string may contain Pango markup, for example "<i>The</i>Guardian".

Fonts are specified pango-style as "family style size", for example "sans 12" or "times italic 14".

The width parameter, if greater than zero, gives the line width to wrap at.

alignment can be 0, 1 or 2 for right, centre and left alignment.

dpi is the resolution to render the text at. 300 is good for print, 100 for displays.
