Terrible Compression #213

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi guys,

I really like this tool. The one caveat is that it is really bad at png 
compression. What I normally do is take a screenshot, save it to the desktop, 
and then re-save it using Preview (I'm on a Mac). Depending on the content, I 
can get ~100 times reduction in file size without loosing any resolution. I 
don't know how trivial it would be, but I think the tool would be much more 
useful if it had better PNG compression.

I'm not really sure about what's available in terms of C++ PNG optimizers, but 
a quick google search turns up:

Thanks,
Tim
