Hi all,

With http://www.gimp.org/tutorials/Simple_Animations/ at hand I'm creating an animation. (vertical lines of chinese symbols, appearing from right to left) I've made several layers, containing parts of the total image, put them in right order and so far, so good. Animation is working.

The problem arises, when I change the opacity of the layers to create a fade-in / fade-out effect. I duplicated the layer that I want to fade in, several times and changed their opacity to,

layer01: 6.2
layer01a: 22.2
layer01b: 39.5
layer01c: 32.1

The animation is still working, but the opacity doesn't change on bit, so the expected fade-in effect is not happening.

Any suggestions?


Perhaps my reply is a mere shot in the dark, yet I imagine that fortmats like PNG will not have the notion of animation (i.e. multiple frames). In fact, I have never come across PNG animations.

'Dropping  back' to GIF, I do not recall ever seeing GIF files with opaci-
ty. I am aware that no-colour can be set in GIF files, essentially a back-
ground  colour  that is undefined in the palette -- a binary  transparency
rather  than an 8-bit channel. Thus, I am inclined to believe that you can
either  have transparencies by using the PNG format or animations (without
opacity) using the GIF.

Hope it contributes,


Roy S. Schestowitz
