Noah Petherbridge 640e75ba4d Custom Wallpapers for Levels
* You can now browse for a custom wallpaper image to use with your
  levels. A platform-native file picker dialog is used (no WASM support)
* In the New/Edit Level Properties dialog, the Wallpaper drop-down
  includes an option to browse for a custom map.
* When editing an existing level: the wallpaper takes effect immediately
  in your level once the file is picked. For NEW levels, the wallpaper
  will appear once the "Continue" button is pressed.
* All common image types supported: png, jpeg, gif.
* The wallpaper is embedded in the level using the filepath
  "assets/wallpapers/custom.b64img" as a Base64-encoded blob of the
  image data.
* The `doodad show` command will list the names and sizes of files
  embedded in levels. `doodad show --attachment <name>` will get an
  attachment and print it to the console window.
* To extract a wallpaper image from a level:
  `doodad show -a assets/wallpapers/custom.b64img | base64 -d > out.png`

doodad.exe

The doodad tool is a command line interface for interacting with Levels and Doodad files, collectively referred to as "Doodle drawings" or just "drawings" for short.

Commands

doodad convert

Convert between standard image files (bitmap or PNG) and Doodle drawings (levels or doodads).

This command can be used to "export" a Doodle drawing as a PNG (when run against a Level file, it may export a massive PNG image containing the entire level). It may also "import" a new Doodle drawing from an image on disk.

Example:

# Export a full screenshot of your level
$ doodad convert mymap.level screenshot.png

# Create a new level based from a PNG image.
$ doodad convert scanned-drawing.png new-level.level

# Create a new doodad based from a BMP image, and in this image the chroma
# color (transparent) is #FF00FF instead of white as default.
$ doodad convert --key '#FF00FF' button.png button.doodad

Supported image types:

  • PNG (8-bit or 24-bit, with transparent pixels or chroma key)
  • BMP (bitmap image with chroma key)

The chrome key defaults to white (#FFFFFF), so pixels of that color are treated as transparent and ignored. For PNG images, if a pixel is fully transparent (alpha channel 0%) it will also be skipped.

When converting an image into a drawing, the unique colors identified in the drawing are extracted into the palette. You will need to later edit the palette to assign meaning to the colors.
