Here are some things to check:
- did you remove the output gd.png file and do a fresh run of ttree?
- use od to compare the binary output files generated by tpage and ttree.
Are they different sizes? Where are they different?
- You probably shouldn't run the gd file through trim:
> PROCESS $template | trim;
since it could contain leading or trailing whitespace (although
png files don't start with whitespace; I'm not sure about the last
bytes. Your sample png file doesn't start or end with whitespace,
so the trim is a no-op).
