possible bug file size of each frame of gif animation IM 6.9.0.4 Q16
Posted: 2015-02-05T18:10:22-07:00
How does one go about listing the actual size of each frame of a gif animation.
Here is an animation I made:
http://www.fmwconcepts.com/misc_tests/a ... tmp1_6.gif
If I use the following to get the animation frame size,
I get the following:
%b shows 0 Bytes for every frame, but the last, which shows 490 KB, for which I assume this is the whole animation size.
%[size] shows 490 KB for all frames
But if I do
I get:
which shows 31.2 KB for both %b and %[size], which I assume is the actual frame size.
Is there some other string format that shows this without the pipe? and why does %b show 0 for all but the last frame?
