Animated GIF to BMP not working?
Posted: 2013-04-01T19:42:57-07:00
I'm trying to use ImageMagick 6.8.3-10 2013-03-17 Q16 to convert an animated GIF to individual BMP frames.
Converting this GIF:
Using: c:\ImageMagick\convert.exe d:\Downloads\tumblr_lv91gcIdBO1r4ybdoo1_500.gif c:\temp\HorseJump\frm%05d.bmp
Results in 26 frames with lots of different frame sizes.
So you're thinking use -coalesce right?
The first frame is OK. The second frame however shifts upwards and incorrectly leaves about 40 pixels of the previous frame at the bottom. Frame 21 to 26 also do not render correctly and leave lots of the fish on the frame instead of animating them correctly.
What would the correct command line options to use to ensure all the frames are the same size and correctly rendered?
