Hi Rasmus,
really? Why works the thumbnail function with php 4.2.3 and gd 1.8.x
perfectly with more than 256 colours and with php 4.3.x not?
How can I compile the GD2 bundled?
What must I change in my configure command?
Thanks a lot
Andreas

Actually, never mind, just took a look at your images. I assume you
were also using gd-1.8 with PHP 4.2.3?

gd-1.x only supports 256 colours. You should be using the bundled
version of gd2 and then ImageCreateTrueColor() instead of ImageCreate()
in your code. Then the thumbnail would look nice.

Hi Derick,
here my thumbnail-function:
function imgthumb($ori,$thump,$thumbQuality,$thumbWidth)
{
$origImageHandle = ImageCreateFromJPEG($ori);
$imageWidth = imagesx($origImageHandle);
$imageHeigth = imagesy($origImageHandle);
$thumbHeigth = floor($thumbWidth * $imageHeigth / $imageWidth);
$thumbImageHandle = ImageCreate("$thumbWidth","$thumbHeigth");
imagecopyresized($thumbImageHandle,$origImageHandle,0,0,0,0,$thumbWidth,$thumbHeigth,imagesx($origImageHandle),imagesy($origImageHandle));
imagejpeg($thumbImageHandle,$thump,"$thumbQuality");
}
Thx for your fast answer
Andreas
