I can try to work on this, but I have to finish some other projects first. So I cannot say exactly when I will have it done. Perhaps within a week.fmw42 wrote:lovelf wrote:You are a real genius on this from what I've seen on Fred's ImageMagick Scripts, is it too much to ask you for the command line syntax to achieve these simple steps.

It would take me quite some time (hours) to do that as I need to figure out how to match PS ellipse and blurring to get the vignette effect close in IM and also to try to match the curves function.
Code: Select all
function vignette($input, $color_1 = 'none', $color_2 = 'black', $crop_factor = 1.5)
{
$img_resource_size=getimagesize($input);
$img_resource_width=$img_resource_size[0];
$img_resource_height=$img_resource_size[1];
$crop_x = floor($img_resource_width * $crop_factor);
$crop_y = floor($img_resource_height * $crop_factor);
$command=("convert
( {$input} )
( -size {$crop_x}x{$crop_y}
radial-gradient:$color_1-$color_2
-gravity center -crop {$this->_width}x{$this->_height}+0+0 +repage )
-compose multiply -flatten
{$input}");
$command = str_replace(array("\n", "'"), array('', '"'), $command);
# replace multiple spaces with one
$command = preg_replace('#(\s){2,}#is', ' ', $command);
# escape shell metacharacters
$command = escapeshellcmd($command);
# execute convert program
exec($command);
}Code: Select all
vignette(img_resource, 'none');
