Thanks for the help guys.. turns out i do have a version of GD in my
php (THANK GOD) (version 2.0.2.8)and seem to have found a script
pre-made that will do what i want it to (take my semi-transparent 1
color image and change it to another color), except im having a
problem having it output the image... using imagepng() i can get the
image to show in the browser, but i want to get this created image to
where i can pull it up in a variable on the actual html page. I tried
the instructions for writing the image to a file and then calling it
up, but no matter what i tried i always got a pretty vague "The image
(instertimagenamehere) cannot be displayed because it contains errors"
when i tried to run the page lol.. i have no luck. Can anyone give me
simple instructions on how i can take the output from a generic called
up imagecreatefrompng() script and put it in some semblence of a
useable form? With it just outputting to browser, it does me no good :x
the example codes on php.net that i saw were way over my head
(obviously ive been hugging my php for dummies lately)
this is the script ive been using:
-----------------------------------------------------------
$image = imagecreatefrompng("myimage.png");
$width = imagesx($image);
$height = imagesy($image);
$colorToChange = "b43b44";
$newColor = "f0f0f0";
$c1 = sscanf($colorToChange,"%2x%2x%2x");
$c2 = sscanf($newColor,"%2x%2x%2x");
$cnew = imagecolorallocate($image,$c2[0],$c2[1],$c2[2]);
for ($y=0;$y<$height;$y++) {
for ($x=0;$x<$width;$x++) {
$rgb = imagecolorat($image,$x,$y);
$r = ($rgb >> 16) & 0xFF;
$g = ($rgb >> 8) & 0xFF;
$b = $rgb & 0xFF;
if (($r==$c1[0]) && ($g==$c1[1]) &&
($b==$c1[2])) {
imagesetpixel($image,$x,$y,$cnew);
}
}
}
header("Content-Type: image/png");
imagepng($image);
