For this test I've used a 1x50 pixel PNG image with 50 different paletted colours. <?php $src_img_file_name = "source_image.png"; // filename of source file $dest_img_width = 150; // destination image width $dest_img_height = 50; // destination image height $src_img_width = 1; // source image width $src_img_height = 50; // source image height // create a blank image $dest_img = @ImageCreate($dest_img_width, $dest_img_height) or die ("Cannot Initialize new GD image stream"); // create image from source image file $src_img = imagecreatefrompng($src_img_file_name); // copy source image to destination image resampled imagecopyresampled($dest_img, $src_img, 0, 0, 0, 0, $dest_img_width, $dest_img_height, $src_img_width, $src_img_height); // copy source image to destination image resized //imagecopyresized($dest_img, $src_img, 0, 0, 0, 0, $dest_img_width, $dest_img_height, $src_img_width, $src_img_height); //send image to output header("Content-type: image/png"); ImagePng($dest_img); ?> ------------------------------------------------------------------------ [2002-06-28 03:02:30] sniper@php.net Please add a short example script here which can be used to reproduce this. ------------------------------------------------------------------------ [2002-05-15 18:21:50] nicolaasuni@tiscali.it Using php_gd2.dll and paletted image the method imagecopyresized return a monochromatic rectangle and the method imagecopyresampled return a blank rectangle. These methods works fine only with true color images. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17263&edit=1
