problem with gd

[hwiens]

Hi,
i got a problem with the gd library at my isp's server.

I've got the following script, to put a string on a image:

<?PHP
header ("Content-type: image/png");

$gd_text = $_GET['stadt'];
$font = "/home/stadt-internetde/public_html/bilder/ariblk.ttf";
//"ariblk.ttf"; ;

$x = imagettfbbox (23, 0, $font, $_GET['stadt']);

if((154 + ($x['2']-$x['0'])+12) < 281) $breite = 281; else $breite = 154 +
($x['2']-$x['0']+12);

$im = ImageCreate($breite ,173);
$im2 = ImageCreateFromJPEG("logo.jpg");

$orange = ImageColorAllocate ($im, 220, 167, 23);
$blau = ImageColorAllocate ($im, 51, 102, 153);
$bgc = ImageColorAllocate ($im, 255, 255, 255);
ImageFilledRectangle ($im, 0, 0, ImageSX($im), ImageSY($im), $bgc);

ImageCopyResized($im, $im2, 0, 0, 0, 0, 281, 173, ImageSX($im2),
ImageSY($im2));


//border -----
$test = ImageTTFText ($im, 23, 0, 154, 58, $blau, $font, $gd_text);
$test = ImageTTFText ($im, 23, 0, 154, 56, $blau, $font, $gd_text);
$test = ImageTTFText ($im, 23, 0, 156, 56, $blau, $font, $gd_text);
$test = ImageTTFText ($im, 23, 0, 156, 58, $blau, $font, $gd_text);
//text --------
$test = ImageTTFText ($im, 23, 0, 155, 57, $orange, $font, $gd_text);

ImageColorTransparent($im , $bgc);
ImagePNG ($im);
ImageDestroy($im);
?>

On my localhost, everything works fine, but on the internetserver, the
created image is very ugly!
On the internet-server i got gd-version 2.0 or higher, so i tried to change
$im = ImageCreate($breite ,173);
to
$im = ImageCreateTrueColor($breite ,173);

but when I use ImageCreateTrueColor the transparency is gone and the image
is still ugly!

Phpinfo shows:
gd support enabled
gd version 2.0 or higher
Freetype support enabled
Freetype linkage with Freetype
JPG support enabled
PNG support enabled
wbmp support enabled

Anyone got an idea for me?

take a look at the manual:
http://de2.php.net/manual/en/functio...ransparent.php

perhaps the first user contributed note might solve your problem (if it doesn't perhaps some of the other will give an idea. You are not alone with that problem )

ok some works...

i had a test-sytem with GDLib, phpinfo shows me this version:
"GD Version 2.0 or higher" so far no porblems with: imageColorTransparent

Then we had to copy ouer codes to another sever on this server phpinfo shots me version:
"GD Version bundled (2.0.12 compatible)"

The jpg was wrong and nothing was transparent.
The point is, you have to use: imagecopymerge

Don't if its true on any system just work on
SUSE 8.2
PHP 4.3.2

and another one

If you have a transparent PNG , in PHP 4.3.1 , GD 2.0 , you don't need to set the transparency anymore , it's automatic ...
