imagecolorallocate — Allocates a color in an image.
string imagecolorallocate(image, red,
int image: Image
int red: Red component
int green: Green
int blue: Blue
imagecolorallocate() creates a color that can be
used in other image functions. The red, green, and blue
components are the standard 0-255 values, and
combinations of each allow for 16,777,216 (256 ^ 3)
possible colors. This function must be called for each
color that's used in the image. It's normally a good idea
to give each assigned color a meaningful variable name
for easy reference.
Example 393. Create a
$im = imagecreate(200, 200);
$turq = imagecolorallocate($im, 75, 200, 150);
imagefill($im, 0, 0, $turq);
