arduboy-aseprite

Aseprite extension for exporting sprites to C data, specifically in Arduboy format.

Installation

Header over to the Releases section and download the latest .aseprite-extension file. Then, double click it to install in aseprite!

Note: You will probably have to restart Aseprite after installation.

Usage

Use File -> Export as C Array to export the current sprite / frame as C code.

After hitting Generate, your C code will come up in a dialog. To copy the text from this dialog, click the text portion and use your OS shortcut key for copying to the clipboard.

Format

• 1 bit (horizontal)
  Data is stored horizontally with each byte representing 8 columns of pixels.
  Note: Any color under mid-gray will be a 0 bit, otherwise a 1 bit.
• 1 bit (vertical)
  Data is stored in the Arduboy format, with each byte representing 8 vertical pixels.
  Note: Any color under mid-gray will be a 0 bit, otherwise a 1 bit.
• 8 bit (indexed)
  Data is stored using the palette index of the pixel. Each pixel consumes 1 byte.
• 32 bit (RGBA)
  Data is stored in RGBA format, where each 4 bytes represent the red, green, blue, and alpha components.

Export Layers

• Individually
  Each layer, whether it is hidden or not, gets generated as it's own C array.

• Flattened Together
  The entire sprite is converted to a single C array, as if the layers have been flattened.

  Template

  You can customize the template used to generate the variable C array. The string NAME will get converted into a friendly name.

  Include Dimensions

  If checked, the first two bytes of the array will be width and height of the sprite.

  Note: If the layer being processed has the work "mask" in it's name, the dimensions will NOT be included.
