ImageTransparency

[flame_211]

I am having problems with Image Transparency, My images I have go in as Transparent, but when I out put them, they arent. Am I doing my imagetransparency function wrong?

function player($guy, $shirt) {

$image = ImageCreateTrueColor($im_x_guy, $im_y_guy);
$im_guy = ImageCreateFromPNG("images/rpg/clothing/$guy");

$im_x_guy = ImageSX($im_guy);
$im_y_guy = ImageSY($im_guy);

$im_color = ImageColorAllocate($image, 0, 0, 0);

ImageColorTransparent($image, $im_color);

ImageCopy($image, $im_guy, 0, 0, 0, 0, $im_x_guy, $im_y_guy);

if ($shirt !== '0'){
$im_shirt = ImageCreateFromPNG("images/rpg/clothing/$shirt");
$im_x_shirt = ImageSX($im_shirt);
$im_y_shirt = ImageSY($im_shirt);
ImageCopy($image, $im_shirt, 0, 0, 0, 0, $im_x_shirt, $im_y_shirt);
}

header ("Content-type: image/png");
ImagePNG($image);
ImageDestroy($image);} 

Any help would be GREATLY apreciated.

Did you check out any of the comments in the PHP manual to see if they'd help? http://www.php.net/ImageColorTransparent

Yeah, I did, I tried like 3 of them, but It doesnt seem to work. Could it be that my server doesnt support ImageTransparency for some reason?

I'm not totally sure if this will do it, but you could try moving your declaration of the transparent color to after the if statement..

if ($shirt !== '0'){ 
$im_shirt = ImageCreateFromPNG("images/rpg/clothing/$shirt"); 
$im_x_shirt = ImageSX($im_shirt); 
$im_y_shirt = ImageSY($im_shirt); 
ImageCopy($image, $im_shirt, 0, 0, 0, 0, $im_x_shirt, $im_y_shirt); 
} 

//move transparency declaration
ImageColorTransparent($image, $im_color);

header ("Content-type: image/png"); 
ImagePNG($image); 
ImageDestroy($image);}

Alright, Ill try it out and let you know how it turns out.

[phpman]

does your server have GD Library 2.0, because you have to have it for it to work.

[flame_211]

["GD Version"]=> string(27) "bundled (2.0.15 compatible)"

thats the version I have, it should work shouldnt it?

[phpman]

where did you get that? what does it say when you run phpinfo() ?

[flame_211]

Hrm... It says it in phpinfo? ill have to check that, anyways, i got that from gd_info();, however its best to probably display it with var dump:

<?php
var_dump(gd_info());
?>

[flame_211]

according to phpinfo() i have 2.0.15

[phpman]

where are these coming from?

$im_x_guy, $im_y_guy

also I don't know any phpinfo that displays the full version. mine says "bundled (2.0 compatible)"

anyway, where are those variables coming from?

did you read the posted code?

function player($guy, $shirt) { 

$image = ImageCreateTrueColor($im_x_guy, $im_y_guy); 
$im_guy = ImageCreateFromPNG("images/rpg/clothing/$guy"); 

$im_x_guy = ImageSX($im_guy); 
$im_y_guy = ImageSY($im_guy); 

$im_color = ImageColorAllocate($image, 0, 0, 0); 

[phpman]

uhh look again

function player($guy, $shirt) { 

$image = ImageCreateTrueColor($im_x_guy, $im_y_guy); 
$im_guy = ImageCreateFromPNG("images/rpg/clothing/$guy"); 

$im_x_guy = ImageSX($im_guy); 
$im_y_guy = ImageSY($im_guy);

he calls them before he sets them.
