vae_image_grey()

Use the vae_image_grey() function to make an image greyscale.

Usage

vae_image_grey($image)

  • $image - Filename for the image you would like to make greyscale. This is usually obtained by calling vae_image() on the image ID (obtained by reading the data returned by vae() under the path of the Image structure you wish to use). This should be an image retrieved from Vae (and thus stored in the local Vae data cache folder).

Returns

Filename of the newly generated image.

Sample Usage

<?php
// Display press photo in greyscale
$bio = vae_find("bio");
$image_filename = vae_image($bio['press_photo']);
$grey_image = vae_image_grey($image_filename);
echo '<img src="' . vae_data_url() . $grey_image . '" alt="My Grey Image" />';
?>
