## NAME
    [Image::ExifTool::HtmlDump](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool%3A%3AHtmlDump/markdown) - Dump information in hex to HTML page

## SYNOPSIS
        use [Image::ExifTool::HtmlDump](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool%3A%3AHtmlDump/markdown);
        my $dump = [Image::ExifTool::HtmlDump](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool%3A%3AHtmlDump/markdown)->new;

## 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
    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.
