Detailed Description

Rectify image.

This filter can be used to use a rectification information block to rectify the given image. It has special support for RectificationLutInfoBlocks by using the raw data pointer for fast access. For other info blocks it will simply use the RectificationInfoBlock::mapping() method to get the information.
