A partire da dei file gif o jpeg ho bisogno di crearne degli altri ridimensionati e salvarli in una cartella. :?:
If you ever want to resize a picture (maybe in order to create a thumbnail), this small function
should help you. It also gives you an idea of how some of the basic image functions of PHP can be
used.
/* resizeToFile resizes a picture and writes it to the harddisk
*
* $sourcefile = the filename of the picture that is going to be resized
* $dest_x = X-Size of the target picture in pixels
* $dest_y = Y-Size of the target picture in pixels
* $targetfile = The name under which the resized picture will be stored
* $jpegqual = The Compression-Rate that is to be used
*/
function resizeToFile ($sourcefile, $dest_x, $dest_y, $targetfile, $jpegqual)
{
/* Get the dimensions of the source picture */
$picsize=getimagesize("$sourcefile");
$source_x = $picsize[0];
$source_y = $picsize[1];
$source_id = imageCreateFromJPEG("$sourcefile");
/* Create a new image object (not neccessarily true colour) */
$target_id=imagecreatetruecolor($dest_x, $dest_y);
/* Resize the original picture and copy it into the just created image
object. Because of the lack of space I had to wrap the parameters to
several lines. I recommend putting them in one line in order keep your
code clean and readable */
$target_pic=imagecopyresampled($target_id,$source_ id,
0,0,0,0,
$dest_x,$dest_y,
$source_x,$source_y);
/* Create a jpeg with the quality of "$jpegqual" out of the
image object "$target_pic".
This will be saved as $targetfile */
imagejpeg ($target_id,"$targetfile",$jpegqual);
return true;
}
