imagegammacorrect
I copy pasted this code from a book I just bought from Atkinson.
The image is in the same folder has the page. The page displays the string. What am I doing wrong ... again? <?php echo "In ima page\n"; //attempt to open image, suppress error messages if(!($image = @imagecreatefromjpeg("deuxpointdeux.jpg"))) { //error, so create an error image and exit $image = imagecreate(200,200); $colorWhite = imagecolorallocate($image, 255, 255, 255); $colorBlack = imagecolorallocate($image, 0, 0, 0); imagefill($image, 0, 0, $colorWhite); imagestring($image, 4, 10, 10, "Couldn't load image!", $colorBlack); header("Content-type: image/jpeg"); imagejpeg($image); exit(); } //adjust gamma, display inputimage, outputimage imagegammacorrect($image, 2.2, 1.571); //send image header("Content-type: image/jpeg"); imagejpeg($image); ?> -- Thanks for your attention.
