but with GIF and PNG files it dosnt save the transparency in the thumbnail, it just makes it black.
is there any way to save the transparency in the thumbnail?
the thumbnail code i have:
Code: Select all
$filename = "test.jpg";
$filename2 = "test_thumbnail.jpg";
$width = 180;
$height = 180;
list($width_orig, $height_orig) = getimagesize($filename);
$ratio_orig = $width_orig/$height_orig;
if ($width/$height > $ratio_orig) {
$width = $height*$ratio_orig;
} else {
$height = $width/$ratio_orig;
}
$image_p = imagecreatetruecolor($width, $height);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);Code: Select all
$image = imagecreatefrompng($filename2);
imagealphablending($image_p, false);
imagesavealpha($image_p, true);
imagepng($image_p, $filename2, 6);Code: Select all
$image = imagecreatefromgif($filename2);
imagealphablending($image_p, false);
imagesavealpha($image_p, true);
imagegif($image_p, $filename2, 100);
