💅 GENPNG(1) — genpng documentation ✨

okay bestie, so this is genpng from the LCOV 2.0 manual group, manual section 1, dated 2026-10-03. She's an internal tool, she's lowkey iconic, and here's literally everything you need to know 🫶

🌸 NAME 🌸

genpng — Generate an overview image from a source file (internal tool)

💀 real talk: the original page has a duplicate NAME block up top. First one just says "genpng - genpng documentation" (lol), and the second one is the actual description above. Both vibes preserved, no info lost 💖

✨ SYNOPSIS ✨

genpng [ -h | --help ]
 [ -v | --version ]
 [ -t | --tab-size tabsize ]
 [ -w | --width width ]
 [ -d | --dark-mode ]
 [ -o | --output-filename output-filename ]
 source-file

---

🎀 DESCRIPTION 🎀

so genpng creates an overview image for a given source code file — and that file can be either plain text or .gcov format. either way, she serves 👑

⚠️ heads up bestie: the GD.pm Perl module has to be installed for this script to work (you can get it from <http://www.cpan.org>). no GD.pm, no image, periodt 😭

also note — genpng is called from within genhtml, so there's usually no need to call it directly. she's a behind-the-scenes main character, iykyk 💅

🦋 OPTIONS 🦋

• -h, --help — Print a short help text, then exit. tiny lil assist, then she's out 🚪
• -v, --version — Print version number, then exit. just the digits, no small talk ✌️
• *-t *tab-size, --tab-size tab-size — Use tab-size spaces in place of tab. every single tabulator sign in the source code file gets replaced by the number of spaces defined by tab-size (default is 4). so like, 4 spaces per tab unless you say otherwise 🧚
• *-w *width, --width width — Set width of output image to width pixel. the resulting image will be exactly width pixel wide (default is 80).

🙈 careful: source code lines which are longer than width will be truncated. she will literally cut them off, no cap 💀

• -d, --dark-mode — Use a light-display-on-dark-background color scheme rather than the default dark-display-on-light-background. yes she has a dark mode, we love a queen who respects the aesthetic 🌙
• *-o *filename, --output-filename filename — Write image to filename. specify a name for the resulting image file (default is source-file.png). name her whatever you want, she'll slay either way 💖
