I have the following code that takes an existing image, creates a new
one from it and writes some white text on top of that image:
<?php
header("Content-type: image/png");
$startingImage = "leftphoto_01.png";
$image = imageCreateFromPNG($startingImage);
//$white = imageColorAt($image, 30, 215);
$white = imageColorAllocate($image, 255, 255, 255);
imageTTFText($image, 24, 0, 10, 25, $white, "arialbd.ttf", "This is a
test");
imagePNG($image);
imagedestroy($image);
?>
Problem is, the "white" text isn't white -- it's a dingy gray color.
>From reading around, I thought maybe if I took an existing white pixel
in the image and used that to set white, that might help (hence the
commented out //$white = imageColorAt... line in my code above) That
didn't help either. (and the pixel I sampled is exactly the shade of
white I want)
I am almost completely unfamiliar with color pallettes and how to
manipulate them. Can someone shed some light on how I can get some
clean, bright white text on my image?
Thanks.
