Harley1979 Posted July 10, 2007 Share Posted July 10, 2007 I am using imagecreatetruecolor within a script for resizing my images which is causing me a problem. For some reason instead of creating a black to my dimensions image like it should do, I am getting "resource id#6" as its value which of course is an invalid image resource. Has anyone else ever experienced this before, what is it and why can I not simply create a blank image? I have a hunch it is something to do with the php/gd setup which to me looks fine. P.S. I am using GD2. Thanks Link to comment https://forums.phpfreaks.com/topic/59231-imagecreatetruecolor-problem/ Share on other sites More sharing options...

Harley1979 Posted July 10, 2007 Author Share Posted July 10, 2007 Here you go: $path = "../gallery/"; $thumbPath = "../gallery/thumbs/"; $max_size = 3000000; $original = $_FILES['imagefile']['tmp_name']; $size = $_FILES['imagefile']['size']; $type = $_FILES['imagefile']['type']; if(isset($original)){ $imageMsg = "You must choose an image to upload"; } if(is_uploaded_file($original)){ if($size > $max_size){ $imageMsg = "The image is just too feckin big!"; $err = true; } if($type == "image/jpeg" || $type == "image/gif"){ // get last image from db $result = mysql_query("SELECT photo FROM gallery ORDER BY id desc LIMIT 1"); $row = mysql_fetch_row($result); // create image name if(empty($row[0])){$photoName = 0;} $photoName = $row[0] + 1; $newName = $photoName.".jpg"; // begin create thumbnail list($width, $height) = getimagesize($original); // set crop size if($width > $height){ $biggestside = $width; } else { $biggestside = $height; } // crop size will be half that of the largest side $croppercent = .15; $cropwidth = $biggestside*$croppercent; $cropheight = $biggestside*$croppercent; // get top left coordinate $cl = array("x"=>($width-$cropwidth)/2, "y"=>($height-$cropheight)/2); // create thumbnail $thumbsize = 75; $thumb = imagecreatetruecolor($thumbsize, $thumbsize); imagecopyresampled($thumb, $original, 0, 0, $cl['x'], $cl['y'], $thumbsize, $thumbsize, $cropwidth, $cropheight); // save to path imagejpeg($thumb, $thumbPath.$newName); list($origWidth, $origHeight) = getimagesize($original); // if our image is not the desired dimension, resample to default dimensions if($origWidth < $origHeight && $origWidth > 450){ $newHeight = 530; $newWidth = $origWidth * ($newHeight/$origHeight); $resizedImage = imagecreatetruecolor($newWidth, $newHeight); imagecopyresampled($resizedImage, $original, 0, 0, 0, 0, $newWidth, $newHeight, $origWidth, $origHeight); } elseif($origWidth > $origHeight && $origHeight > 530){ $newWidth = 550; $newHeight = $origHeight * ($newWidth/$origWidth); $resizedImage = imagecreatetruecolor($newWidth, $newHeight); imagecopyresampled($resizedImage, $original, 0, 0, 0, 0, $newWidth, $newHeight, $origWidth, $origHeight); } // copy image to folder $res = imagejpeg($resizedImage, $path.$newName); if(!$res){ $imageMsg = "Upload failed!"; $err = true; } else { $imageMsg = "Upload successful"; } } else { $imageMsg = "Wrong file type!"; $err = true; } Thanks Link to comment https://forums.phpfreaks.com/topic/59231-imagecreatetruecolor-problem/#findComment-294259 Share on other sites More sharing options...
