Detailed Description

An empty image can be created with:

drainage --geometry 200,100     -o img-200x100.png
drainage --geometry 200,100,3   -o img-200x100-rgb.png
drainage --geometry 200,100,3,1 -o img-200x100-rgba.png

Member Function Documentation

traverseChannel()

virtual void traverseChannel ( Channel &  dst ) const

inlinevirtual

Run this modifier for an image frame.

The default implementation calls applyToEachChannel(Channel &) for each image. Run this modifier for an image frame. The default implementation calls traverseFrame(ChannelView & dst) for each image.

Reimplemented from ImageMod.
