Combining images with php (GC)

[pleek]

Ok, so im learning GC and alls going well but im stuck. The second image that is supposed to merge with $background isn't showing up.

 

<?php

header('Content-type: image/png');
$String = $_GET['text'];
$UserRank = imagecreatefrompng('elitemember.png');
$UserAvatar = imagecreatefromgif('avatar.gif');
$Background = imagecreatefrompng('Background.png');
$TextColor = imagecolorallocate($Background, 225, 225, 225);
$Font = imageloadfont('Kozuka Gothic Pro B.gdf');
imagestring($Background, $Font, 90, 15, $String, $TextColor);
imagecopymerge($Background, $UserRank, 110, 55, 0, 0, 128, 28, 100);
imagecopymerge($Background, $UserAvatar, 20, 20, 0, 0, 160, 160, 100);
imagepng($Background);
imagedestroy($Background);
imagedestroy($UserRank);
imagedestroy($UserAvatar);
?>

 

The image $UserAvatar is not showing up but $UserRank is. Also how can i stop the transparent parts in $background from turning black? Here is the result

anybody? lol bump!

A) It's GD, not GC

B) How big is UserRank? Maybe it's covering UserAvatar?

 

And I don't see where you set the transparency for $background

if you clicked the "here is the result" link you can see how big userrank is. It 128 * 28. And im not sure how to set the transparency for $background. How do i do that? And yes i know its GD not GD. But i didn't notice my error till after i posted it and it won't let me edit it.

alright, that helped me out. I had seen that but i overlooked part of it. Now, can anybody tell me why i can't get gifs to load with createimagefromgif? pngs work fine.

[pleek]

bump* i can put as many pngs as i want using imagecopymerge and imagecopy. But beyond the background gif i can't get any more gifs to work. And now that i got the transparencies working the imagestring won't show up. heres the new code.

 

 

<?php

header('Content-type: image/png');

// Set a White & Transparent Background Color
$new_image = ImageCreateTruecolor(345, 130);
$bg = ImageColorAllocateAlpha($new_image, 255, 255, 255, 127); // (PHP 4 >= 4.3.2, PHP 5)
ImageFill($new_image, 0, 0 , $bg);


$String = $_GET['text'];
$UserRank = imagecreatefrompng('elitemember.png');
$UserAvatar = imagecreatefrompng('avatar.png');
$Background = imagecreatefromgif('Background.gif');
$TextColor = imagecolorallocate($Background, 225, 225, 225);
$Font = imageloadfont('Kozuka Gothic Pro B.gdf');
imagecopymerge($new_image, $Background, 0, 0, 0, 0, 345, 130, 50);
imagecopymerge($new_image, $UserRank, 110, 55, 0, 0, 128, 28, 100);
imagecopy($new_image, $UserAvatar, 0, 0, 0, 0, 128, 128);
imagestring($new_image, $Font, 90, 15, $String, $TextColor);
imagepng($new_image);
imagedestroy($new_image);
imagedestroy($Background);
imagedestroy($UserAvatar);
imagedestroy($UserRank);
?>
