# MMD PDF

MMD Steel Group's corporate PDF editor for Windows.

This is a fork of **KillerPDF 1.7.5** by Steve the Killer (https://github.com/SteveTheKiller/KillerPDF),
licensed **GPL-3.0**. This fork stays GPL-3.0 and its complete corresponding source is this repository.

## What MMD changed

- **Edited text is really removed.** Upstream lays an opaque cover over the original text run and
  draws the replacement on top, leaving the original glyphs in the file - text extraction returned
  the old value as well as the new one. `Services/PdfRedactText.cs` walks the page content stream at
  save time and blanks every text-showing operator whose origin sits inside a cover, so an edited
  figure is gone from the file rather than hidden.
- **One theme.** `Themes/MMD.xaml` is the only theme: C8102E red used sparingly, 23221E ink,
  F1F1EC platinum, FFFFFF paper, square corners, no grain, no glyph shadows. The other twelve themes,
  the accent overlays and the theme picker are gone. There is no dark mode.
- **Corporate chrome.** Product name, icon and word-mark are MMD; the upstream author credit in the
  status bar and the in-app 'install me' button are removed.
