Feature Request: Watermark.

At present the watermark is shown in gray and it makes it unreadable.What changes should be made to below code to get  watermark as shown in below links , and can this feature be added in next tidypics release?

// transparent gray

imagealphablending($image, true);

$textcolor = imagecolorallocatealpha($image, 50, 50, 50, 60);

 

// font and location

$font = $CONFIG->pluginspath . "tidypics/fonts/LiberationSerif-Regular.ttf"; 

$bbox = imagettfbbox(20, 0, $font, $watermark_text);

 

$text_width = $bbox[2] - $bbox[0];

$text_height = $bbox[1] - $bbox[7];

 

$image_width = imagesx($image);

$image_height = imagesy($image);

 

$left = $image_width / 2 - $text_width / 2;

$top = $image_height - 20;

 

// write the text on the image

imagettftext($image, 20, 0, $left, $top, $textcolor, $font, $watermark_text);

}

 

function tp_imagick_watermark($filename) {

 

$watermark_text = get_plugin_setting('watermark_text', 'tidypics');

if (!$watermark_text)

return;
