From manual page: http://www.php.net/function.imagescale

I would like to use this function, just do not do what I expect.

Test script:
---------------
$old_width = imagesx( $image_resource );
$old_height = imagesy( $image_resource );

$percent = 10;

$new_width = $width * $percent;
$new_height = $height * $percent;

// BLURRED
$new_image_resource = imagescale( $image_resource, $new_width, $new_height );

// THE IMAGE IS SHARP NOW, BUT HAS A BLACK BORDER ON THE LEFT AND BELOW.
$new_image_resource = imagescale( $image_resource, $new_width, $new_height, IMG_BILINEAR_FIXED | IMG_BICUBIC_FIXED );

// CREATES A CLEAN MAGNIFICATION.
$new_image_resource = imagecreatetruecolor( $new_width, $new_height );
imagecopyresized( $new_image_resource, $image_resource, 0, 0, 0, 0, $new_width, $new_height, $old_width, $old_height );
