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