Re^2: reversed colors png images.

I'm making an animated gif with perl and i'm using the gd module. I use the newFromPng method to import images. Then i'm working on an animation that looks like:

use GD;
$img = GD::Image->newFromPng('test1.png');
$img2 = GD::Image->newFromPng('test2.png');
$img3 = GD::Image->newFromPng('test3.png');
$data = $img->gifanimbegin(1,0);
$data.=$img->gifanimadd(0,0,0,1);
$data.=$img2->gifanimadd(0,0,0,1);
$data.=$img3->gifanimadd(0,0,0,1);
$data.=$img->gifanimend;
binmode STDOUT;
print $data;

I can't provide code to demonstrate my problem.But my problem is that the image colors get mixed up, so the screen starts blinking.

Are your 3 images all the same size? What is the logic for adding the same image twice with just 1 x 1/100th of a second delay each? Do you expect to see the animation of 3 images, displayed for 0.02, 0.01 & 0.01 seconds each respectively, to actually visibly move?

Have you tried `gifanimadd(1,0,0,1)`?	[reply]
