You can also use ImageMagick. That makes it easy to generate standardized covers from the command line. The following unix shell script generates a bare-bones cover, save it as 'generatecover', make it executable, and run it as
./generatecover "<author>" "<title>"
, and it'll generate a cover.jpg file:
Code:
#!/bin/sh
author="$1"
title="$2"
font="Times-Roman"
convert -size 600x800 xc:khaki -gravity Center -fill black -font $font \
-pointsize 72 -annotate +0-100 "${author}" \
-pointsize 64 -annotate +0+100 "${title}" cover.jpg
