What I would like to be able to do is to draw one image transparently over another.
This is my function so far:
function create_image()
{
global $im1;
$im1 = @ImageCreateFromJPEG("d:\\projects\\graphics\\image1.jpg");
if(!$im1){
return false;
exit;
}
$im2 = @ImageCreateFromJPEG("d:\\projects\\graphics\\image2.jpg");
if(!$im2){
return false;
exit;
}
/* $color = ImageColorAt($im2, 0, 0);
$color = ImageColorsForIndex($im2, $color);
$color = ImageColorAllocate($im2, $color[0], $color[1], $color[2]);
$result = ImageColorTransparent($im2, $color);*/
$result = ImageCopy($im1, $im2, 10, 10, 0, 0, @ImageSX($im2) - 1, @ImageSY($im2) -
1);
if(!$result){
return false;
exit;
}
// ImageColorDeAllocate($im2, $color);
return true;
}
As long as I keep the lines that are commented out, it works fine (but no
transparency). As soon as I uncomment the ImageColorAt function, I get an error. Any
suggestions on where to proceed from here would be greatly appreciated. Also, if
someone has a better suggestion as to how to accomplish what I am trying to, I'm all
for that as well.
