I was wondering if you could help me. I had got a script working using Imagemagick and then found out the hosts had disabled exec functions due to safety reasons, fair enough but then I had to learn GD, fair enough too but I’m missing something.

Here is my original code:

# $img = “pathtoimage/image.jpg”;
# $size = GetImageSize($img);
# $dim = “300×300+0+0″;
# echo $size[0] . ” ” . $size[1];
# // Wide Image
# if($size[0] > $size[1]) {
# $thumbnail_height = 300;
# $thumbnail_width = (int)(300 * $size[0] / $size[1]);
# }
#
# // Tall Image
# else{
# $thumbnail_height = (int)(300 * $size[1] / $size[0]);
# $thumbnail_width = 300;
# }
#
# $mogrify = “pathtimagemagick/mogrify -geometry”;
# $crop = “pathtimagemagick/mogrify -gravity Center -crop”;
# system(”$mogrify $thumbnail_heightx$thumbnail_width $img”, $exec_retval);
# system(”$crop $dim $img”, $exec_retval);

and here is the GD code that I was given:

function resize_image($upload_directory, $new_image_name)
{
// original image location //
$original_image = $upload_directory;

// set up a canvas sizes //
$canvas_width = 65;
$canvas_height = 65;

// create the canvas //
$canvas = imagecreatetruecolor($canvas_width, $canvas_height);

// make the background color white //
$white_background = imagecolorallocate($canvas, 255, 255, 255);

// change the background to white //
imagefill($canvas, 0, 0, $white_background);

// get the image height and width //
list($image_width, $image_height) = getimagesize($upload_directory);

#########################################
// RATIO CALCULATIONS //
$ratio = $image_width / $image_height;

if ($ratio > 1 )
{

$new_image_width = 65;
$new_image_height = 65 / $ratio;

} else {

$new_image_width = (float) 65 * $ratio;
$new_image_height = 65;

}
// RATIO CALCULATIONS //
#########################################

// store original into memory //
$original_image = imagecreatefromjpeg($original_image);

// copy the original image onto the canvas canvas, original and top/left co-ordinates //
imagecopyresampled($canvas, $original_image, 0,0,0,0, $new_image_width, $new_image_height, $image_width, $image_height);

// thumbnail name //
$new_thumbnail_name = “thumb-$new_image_name”;

// save the thumbnail in the thumbs folder //
if(imagejpeg($canvas, “products/thumbnails/$new_thumbnail_name”, 100))
{
return(”$new_thumbnail_name”);
}

// destroy the images in memory //
imagedestroy($original_image);
imagedestroy($canvas);

} // end function //

it resizes but then it displays the image in a 300×300 canvas (not cropped) with a blank bit.

Any suggestions would be extremely appreciated

I am pasting the script below:

Ouch…
