Ok, after converting this to hex, switching the endianess (I'm on
a sparc/solaris box currently) you can see the files are:
farside 1% od -c bad.png
0000000 \r \n 211 P N G \r \r \n 032 \r \n \0 \0 \0 \r
0000020 I H D R \0 \0 \0 310 \0 \0 \0 d 001 003 \0 \0
[snip]
farside 2% od -c good.png
0000000 211 P N G \r \n 032 \n \0 \0 \0 \r I H D R
0000020 \0 \0 \0 310 \0 \0 \0 d 001 003 \0 \0 \0 371 H 355
[snip]
There are two problems:
- the bad file has a initial newline (\n or 0xa)
- every newline in the bad file has an extra return (\r or 0xd).
The initial newline is most likely some extraneous whitespace introduced
somewhere in your template. Since it only happens with ttree you should
look at the wrapper. Remove the GD althogether (or replace it with a
single string, say "XXX") and make sure you get no output (or just "XXX").
The replacement of \n with \r\n is a windoze text versus binary mode
issue. You need to change the output to binary mode on windoze. Try
using stdout(binmode) or redirect(file, binmode).
