Imagick Extension for SilverStripe

Requires a SilverStripe 3.* install and PHP Imagick configured for your PHP install.

On ubuntu, this was as easy as:

sudo apt-get install php5-imagick
sudo php5enmod imagick

followed by restarting apache.

Once it has been added, you will have access to the following additional Image functions:

  • BlurredImage($radius, $sigma)
    • Blurs an image using the Imagick::blurImage() function
    • @param $radius - The radius of the blur
    • @param $sigma - The standard deviation of the blur
  • ColourTransparentImage($colour)
    • Fully colours an image in a single colour, preserving any opacity
    • @param $colour - A colour string to give the image
  • ColourOverlayImage($colour, $opacity)
    • Overlays a colour on top of an image, with a varying degree of opacity
    • @param $colour - A colour string to give the image
    • How transparent the overlay should be, from 0.0 - fully transparent to 1.0 - a block colour

NOTE: Currently, the $colour parameter only supports strings being passed, eg. "red", "blue", "green" will work, but "#ff0000", "#00ff00" and "#0000ff" will not.
