in reply to Creating an animated gif with GD

I tried a mix of GD and GD::Image::AnimatedGif. I used the sample from GD, but I kept it very simple. I just wanted the blue border of the red oval to expand and contract when I passed over it with my mouse. It's almost imperceptible, but it works.
#!/usr/bin/perl use strict; use warnings; use GD; use GD::Image::AnimatedGif; my $im_width = 100; my $im_height = 100; my $im = new GD::Image($im_width, $im_height); my $white = $im->colorAllocate(255,255,255); my $black = $im->colorAllocate(0,0,255); my $red = $im->colorAllocate(255,0,0); my $blue = $im->colorAllocate(0,0,255); $im->rectangle(0,0,99,99,$black); $im->arc(50,50,95,75,0,360,$blue); $im->fill(50,50,$red); my $gifdata = $im->gifanimbegin; my $frame = GD::Image->new($im->getBounds); $gifdata = $frame->gifanimadd; my $loop = 0; my $speed = 82; $gifdata .= $im->gifanimend; print "Content-type: image/gif\n\n"; print $im->animated_gif($loop, $speed);

    Should cpanminus be part of the standard Perl release?
