note 81854 added to function.imagejpeg

Here is a function to resize an image and maintain aspect ratio. It will resize jpeg, gif or png and could easily be modified to add bmp. The name field is the destination of the file minus the file extension: <?php //name= filename minus type function createImage($uploadedfile,$newWidth,$name) { // Capture the original size of the uploaded image if(!$info=getimagesize($uploadedfile)) return false; switch ($info['mime']) { case 'image/jpeg': $src = imagecreatefromjpeg($uploadedfile); break; case 'image/gif': $src = imagecreatefromgif($uploadedfile); break; case 'image/png': $src = imagecreatefrompng($uploadedfile); break; default: return false; } //Change the filename to add the filetype $mime=split("image/",$info['mime']); $filename=$name.".".$mime[1]; $size = getimagesize($uploadedfile); $newHeight=aspect_ratio($size[0],$newWidth,$size[1]); $tmp=imagecreatetruecolor($newWidth,$newHeight); // this line actually does the image resizing, copying from the original // image into the $tmp image imagecopyresampled($tmp,$src,0,0,0,0,$newWidth,$newHeight,$info[0], $info[1]); switch ($info['mime']) { case 'image/jpeg': imagejpeg($tmp,$filename,100); //100 is the quality settings, values range from 0-100. break; case 'image/gif': imagegif($tmp,$filename,100); //100 is the quality settings, values range from 0-100. break; case 'image/png': imagepng($tmp,$filename); //100 is the quality settings, values range from 0-100. break; } imagedestroy($src); imagedestroy($tmp); // NOTE: PHP will clean up the temp file it created when the request // has completed. return true; } if(!createImage($uploadedfile,100, "uploaded_images/imgname")) { echo "error"; } ?> ---- Server IP: 83.170.119.58 Probable Submitter: 81.154.215.249 ---- Manual Page -- http://www.php.net/manual/en/function.imagejpeg.php Edit -- https://master.php.net/note/edit/81854 Del: integrated -- https://master.php.net/note/delete/81854/integrated Del: useless -- https://master.php.net/note/delete/81854/useless Del: bad code -- https://master.php.net/note/delete/81854/bad+code Del: spam -- https://master.php.net/note/delete/81854/spam Del: non-english -- https://master.php.net/note/delete/81854/non-english Del: in docs -- https://master.php.net/note/delete/81854/in+docs Del: other reasons-- https://master.php.net/note/delete/81854 Reject -- https://master.php.net/note/reject/81854 Search -- https://master.php.net/manage/user-notes.php
