![]() ![]() I think your problem lies in the way color-to-alpha works: by definition, the color and transparency produced by color-to-alpha is such that if placed over a layer filled by the removed color, you get back the original layer. Sample-trans-color to alpha.gif Ĥ-new-black-gray-white.gif Again, i have been able to select just the outside boxes and make a mask, but i am unable to change the color to the correct color and then i also am unable to select just the inside boxes at all.Īny help would be GREATLY GREATLY appreciated.įile comment: after layer trans color to alpha I believe i can do adjustment from one layer and can copy adjustment and apply to other layers. The smaller outside boxes are to be color d9d9d9 or (217,217,217) and the two bigger inner boxes are to be color bfbfbf (191,191,191). If someone could just help me with one layer, i can apply steps to other layers. I have read because i am using "gray" that this can happen, but i have been unable to correct as i seem to be having a problem with the select tool. When i do this, it fades out the colors of my original image. I highlight a layer, do layer, trans, color to alpha make sure color is correct and apply. The next step is what creates the problem. I then paste each slide as a new layer in the order they need to be. I have opened new and set a background layer as transparent. The baclground is or needs to be transparent. They are all basically the same, except the arrows on each slide are in a different place as this will be an animated gif. ![]() The project was done in powerpoint and each slide was saved as a gif separately. but Gimp is all I have right now, and I'm just learning to use it I had never even touched a program like this until just 3 weeks ago and the learning curve is STEEP, lol.I have been having a problem wih layers and losing original gif color. The old format isn't much of a problem for real animations where all frames are variations of the same and therefore share a lot of colors, but doesn't really cut it for slide shows. A more recent extension of the format allows a 256-color color map per frame. Gimp only supports the original GIF format, with a color map of 256 colors common to all frames.

I have 3 different options for dithering in the drop-down, and also an option for dithering of transparency… Which of these do I use?

It is possible to have an animation where each 'frame ' still only has 256 colours, but a different set of 256 colours for each frame (Gimp can only use 1 set of 256 colours for everything). If you want better than that, Gimp is not the tool. Now export that as an animated gif, you still only have 256 colours but those are now in small graded areas. ![]() To get around that, convert your layered image to Indexed Image -> Mode -> Indexed before exporting to an animated gif. Exporting to a gif gets blocks of solid color. The four images have to be reduced to 256 colours. Make sure you start off in RGB mode, look at the top of the Gimp window to check. You have 4 very different images (I took these from Google), each with thousands of different colours. It looks awful because a gif file can only contain a maximum 256 colours. ![]()
