problem creating jpg thumb with php
- by Ross
Hi,
I am having problems creating a thumbnail from an uploaded image, my problem is
(i) the quality
(ii) the crop
http://welovethedesign.com.cluster.cwcs.co.uk/phpimages/large.jpg
http://welovethedesign.com.cluster.cwcs.co.uk/phpimages/thumb.jpg
If you look the quality is very poor and the crop is taken from the top and is not a resize of the original image although the dimesions mean it is in proportion.
The original is 1600px wide by 1100px high.
Any help would be appreciated.
$thumb =
$targetPath."Thumbs/".$fileName;
$imgsize =
getimagesize($targetFile); $image =
imagecreatefromjpeg($targetFile);
$width = 200; //New width of image
$height = 138; //This maintains
proportions
$src_w = $imgsize[0]; $src_h =
$imgsize[1];
$thumbWidth = 200; $thumbHeight =
138; // Intended dimension of thumb
// Beyond this point is simply code.
$sourceImage =
imagecreatefromjpeg($targetFile);
$sourceWidth = imagesx($sourceImage);
$sourceHeight = imagesy($sourceImage);
$targetImage =
imagecreate($thumbWidth,$thumbHeight);
imagecopyresized($targetImage,$sourceImage,0,0,0,0,$thumbWidth,$thumbWidth,imagesx($sourceImage),imagesy($sourceImage));
//imagejpeg($targetImage,
"$thumbPath/$thumbName");
imagejpeg($targetImage, $thumb);
chmod($thumb, 0755);
