# [DESCRIPTION](#DESCRIPTION)

This module contains code used to generate an HTML-based hex dump of information for debugging purposes. This is code is called when the ExifTool 'HtmlDump' option is used.

Currently, only EXIF/TIFF and JPEG information is dumped.

# [BUGS](#BUGS)

Due to a memory allocation bug in ActivePerl 5.8.x for Windows, this code may run extremely slowly when processing large files with this version of Perl.

An HTML 4 compliant browser is needed to properly display the generated HTML page.
