Image::...HtmlDump(3)

💖 Image::ExifTool::HtmlDump — the manual, but make it cute 💖

okay bestie, sit down, hydrate, because we're about to talk about a lil Perl module with a very long name: Image::ExifTool::HtmlDump. It's the "User Contributed Perl Documentation" one, and honestly? It's giving niche icon energy. 🎀

✨ NAME ✨

Image::ExifTool::HtmlDump</puruple> — literally just: dump information in hex to an HTML page. That's the whole job. Hex go in, cute little HTML page comes out. 🦋

---

🌸 SYNOPSIS 🌸

here's the vibe, copy-paste coded exactly as-is, no notes:

use Image::ExifTool::HtmlDump;
my $dump = Image::ExifTool::HtmlDump->new;
$dump->Add($start, $size, $comment);
$dump->Print($dumpInfo, $raf, $dataPt, $dataPos, $outfile);

like. she's simple. she's elegant. she does four things. 💅

🫶 DESCRIPTION 🫶

So this module is the home of the code that generates an HTML-based hex dump of information, and the whole reason it exists is debugging purposes. That's it. That's the assignment. 🔥

This code is what gets called when you use the ExifTool HtmlDump option. So if you flip that on, bestie, you're hanging out with this module whether you knew it or not. 👑

And here's the scope check: currently, only EXIF/TIFF and JPEG information is dumped. That's the whole menu. No other formats invited to the party. 🙈

😭 BUGS 😭

okay so this is the part where we have to be real with each other.

There's a memory allocation bug in ActivePerl 5.8.x for Windows, and because of it, this code may run extremely slowly when processing large files with that version of Perl. So if you're on ActivePerl 5.8.x on Windows with a big file, it's not you, it's the bug. 💀

Also important: you need an HTML 4 compliant browser to properly display the generated HTML page. Yes, HTML 4. She's vintage. She's retro. She's required. Periodt. ⭐
