Gif with transparent color

[Granular]

Hello! I tried to create an animation with transparent background using the utility "convert" and saw the problem.

Code: Select all

convert.exe -transparent red  -delay 20 *.bmp 3.gif

1.bmp -
2.bmp -
3.gif -

The second picture shows without erasing the first. Please tell me the solution to this problem.

jpg does not have a solid red color, so you need to use -fuzz. second, the -transparent should be after the input images. third you need to set the disposal method.

try

convert -dispose background -delay 50 1.jpg 2.jpg -fuzz 20% -transparent red -loop 0 3.gif

You also need to set the appropriate disposal.

NOTE that all frames are disposed of completely at the end of the loop, before looping. The last frames disposal setting is thus irrelevant.
