# Image::ExifTool::WriteCanonRaw(3pm)

Write Canon RAW (CRW and CR2) information

## NAME

Image::ExifTool::WriteCanonRaw.pl - Write Canon RAW (CRW and CR2) information

## SYNOPSIS

These routines are autoloaded by Image::ExifTool::CanonRaw.

## DESCRIPTION

This file contains routines used by ExifTool to write Canon CRW and CR2 files and metadata.

## NOTES

The CRW format is a pleasure to work with.  All pointer offsets are relative to the start of the data for each directory.  If EXIF/TIFF had implemented pointers in this way, it would be MUCH easier to read and write TIFF and JPEG files, and would lead to far fewer problems with corrupted metadata.
