  • of(bits): BpxDrawingPattern

  • Creates a BpxDrawingPattern from a numeric representation of 4 columns and 4 rows. Recommended way is to defined the pattern as a binary number, with group separator put between each 4 digits, e.g. 0b0101_1010_0101_1010. The 1 stands for the primary color and the 0 – for the secondary one.

    Parameters

    • bits: number

    Returns BpxDrawingPattern

Static values

StaticprimaryOnly

primaryOnly: BpxDrawingPattern = ...

The pattern used by default, which uses the primary color only. An equivalent of BpxDrawingPattern.of(0b1111_1111_1111_1111).

StaticsecondaryOnly

secondaryOnly: BpxDrawingPattern = ...

The pattern which uses the secondary color only. An equivalent of BpxDrawingPattern.of(0b0000_0000_0000_0000).

Other

hasPrimaryColorAt

  • hasPrimaryColorAt(x, y): boolean

  • The method to check whether a primary or a secondary color should be put at a given (X,Y) when this pattern is applied.

    Usually, you wouldn't have to use this method, since it's already used by internals of BeetPx drawing API.

    Parameters

    • x: number
    • y: number

    Returns boolean
