Image Effects

The Image Effects module provides a suite of additional image effects that
can be added to image styles. Image styles let you create derivations of images
by applying (a series of) effect(s) to it. Think of resizing, desaturating,
masking, etc.

The additional effects that Image Effects provides include:

• Watermark: place a image with transparency anywhere over a source picture.
• Overlay: add photo-corners etc to the image
• Text overlay: add e.g. a copyright notice to your image.
• Color-shifting: colorize images.
• Brighten/Darken.
• Alpha blending: use a gray scale image to define the transparency layer of an
  image.
• Canvas manipulation: resize the canvas and add a background color or image.
• File Format switcher: if you need transparency in JPGs, make them PNG. If your
  PNG thumbnails are 30K each, save them as JPGs.
• Rounded corners.

These effects are grouped in sub-modules. Just enable the ones you want to use.
