Dumd image editor

You know about Paint the software ? Well it's the same but in worse, you can just just use .dumb files and edit them. You can draw with 4 different colors, erase, and export!!!!! WOOOOW Oh and it's also the fdf project from 42, so you can open .fdf maps

Quick start

Build:

make

Run:

• Start with a blank image:

  ./fdf
  

• Edit an existing drawing:

  ./fdf previous_drawing.dumb
  

• Open an FDF map:

  ./fdf map.fdf
  

You can draw on .fdf maps and export them as .dumb.

Features

• Simple paint-like interface
• Four drawing colors + eraser
• Open and edit .dumb files
• Open .fdf maps (from the 42 project) and draw on them
• Export drawings with automatic versioned filenames

Controls

• P — Pen mode (draw)
• D — Eraser mode (toggle)
• E — Export the current image (see versioning rules below)

Colors:

• R — Red
• G — Green
• B — Blue
• W — White
• 0 — Black

Export / Versioning

Press E to export the current image. You can:

• Specify a filename when launching (e.g. ./fdf file.dumb) — exporting will create a new file with an incremented version, for example file_V1.dumb, file_V2.dumb, etc.
• If the provided filename already contains a version suffix (e.g. file_V4.dumb), the exporter will increase the version number (file_V5.dumb).
• If no filename was provided at launch, the program generates a name automatically and adds a version suffix.

.dumb file format

• First 4 bytes: width (integer)
• Next 4 bytes: height (integer)
• Remaining bytes: pixel data (raw image data)

(Format is binary — keep that in mind when inspecting files.)
