Imagecolortransparent() trouble

[ch4rli3]

Hi guys,

i have trouble with my imagecolortransparent from gd library. On one server everything works fine, but if i moved it to hosting server it not works.

 

here's code:

 

<?php

 

$width = 0;

$height = 0;

list($width, $height, $type, $attr) = getimagesize('img/design/GA_preview.png');

if(!$image=imagecreatefrompng('img/design/GA_preview.png')){

        echo "Error while loading image";

        exit;

}

 

$color_1 = imagecolorat($image, 50,50);

$result = imagecolortransparent($image,$color_1);

if(!$bg=imagecreatefrompng('img/material/B1_E475_preview.png')){

              echo "Error while loading image";

              exit;

}

imagecopy($bg, $image, 0,0,0,0,$width, $height);

Header("Pragma: No-cache");

Header("Cache-Control: No-cache, Must-revalidate");

Header("Expires: ".GMDate("D, d M Y H:i:s")." GMT");

header("Content-type: image/jpeg");

imagejpeg($bg, "", 100);

imagedestroy($image);

imagedestroy($bg);

 

 

?>

 

 

this is how it should look: http://212.111.5.196:8088/graspo/diar_vyvoj/test.php

 

and this is how it looks: firemnidiar.graspo.com/diar/test.php

 

for better solving of my problems here are phpinfo files on both servers:

 

working: http://212.111.5.196:8088/graspo/diar_vyvoj/info.php

 

not working: firemnidiar.graspo.com/diar/phpinfo.php

This is a wild guess, because I can't see anything else that is wrong if it works on your server with the exact same code, but are you sure the script are able to get to get the images using the function imagecreatefrompng()?

Yes i'm sure, because i try to draw on top $bg and $image...both was drawn

Try using imagecopymerge instead of imagecopy.  It should have the effect your after.  As for why it works on one server but not the other, I don't know.  One of them is compiled with the bundled GD library while the other appears to use the system library.  There must be some small difference between the two that is causing the different output

imagecopymerge not works too....everything directing to troubles with transparency, but i dont know, where to look for that what change in configuration of php

Might be helpful, might be just a waste of time, but maybe if you create the image first...

imagecreastetruecolor()

and then copy it over.

Might also be you must use one of these:

imagesavealpha()

imagealphablending()
