Some Poster55 Posted December 31, 2008 Share Posted December 31, 2008 Hi, Basically, I'm looking for some help with resizing a png image that has a transparent background. Here's what I'm currently working with: <?php $image1 = imagecreatefrompng("first_image.png"); $width = 59; $height = 112; $newwidth=70; $newheight=112; $image2=imagecreatefrompng("blank_background.png"); imagecopyresampled($image2,$image1,0,0,0,0,$newwidth,$newheight,$width,$height); imagepng($image2,"result.png",9); imagedestroy($image1); imagedestroy($image2); ?> The "first_image.png" file is the image with a transparent background which I need to resize. The "blank_background.png" is a completely transparent and blank image which I'm using to resize the first image using the imagecopyresampled() function. However, upon running the script, I end up with my original image perfectly resized - but with a white background instead of a transparent background. How can I resize the original image, but with retaining the transparent background? Help would be greatly appreciated, thanks! Quote Link to comment Share on other sites More sharing options...
GingerRobot Posted December 31, 2008 Share Posted December 31, 2008 You'll need to save the alpha channel information of $image2 before you save it with imagesavealpha Quote Link to comment Share on other sites More sharing options...
