This example will show you how to Upload a Image and resample the image proportionally with 100% quality, I have made a function it will do the needful, so you don't have to change the function, If you want to change you can change it, I am not going to charge anyway.
| Function |
<?
function SafMakeThumb($img_src, $img_th,$quality=100,$new_w=150,$new_h=150){
$img_size = GetImageSize ($img_src);
$img_in = ImageCreateFromJPEG ($img_src);
list($old_x, $old_y) = getimagesize($img_src);
if ($old_x > $old_y) {
$img_x=$new_w;
$img_y=$old_y*($new_h/$old_x);
}
if ($old_x < $old_y) {
$img_x=$old_x*($new_w/$old_y);
$img_y=$new_h;
}
if ($old_x == $old_y) {
$img_x=$new_w;
$img_y=$new_h;
}
$img_out = ImageCreateTrueColor($img_x, $img_y);
ImageCopyResampled ($img_out, $img_in, 0, 0, 0, 0, $img_x, $img_y, $img_size[0], $img_size[1]);
ImageJPEG ($img_out, $img_th, $quality);
ImageDestroy ($img_out);
ImageDestroy ($img_in);
}
?> |
When you are uploading the file from form use "fldFile" as file field
| Calling the function |
<?
$uploadDir = "$DOCUMENT_ROOT/uploadfiles/";
$fldFileUploadFile = $uploadDir . $_FILES['fldFile']['name'];
if (move_uploaded_file($_FILES['fldFile']['tmp_name'], $fldFileUploadFile)){
$img_th = $fldFileUploadFile. '.thumb.jpg';
make_thumb($fldFileUploadFile,$img_th,100,120,120);
}
?> |
