  Type parameters

  • Change: BimChangeDwg | BimChangeBlob = BimChangeDwg

  Parameters

  • _api: BimCoreApi

    Api

  • _textureSize: number = 1024

    Defines size of texture used to render drawings. Recommended value is power of two. Higher resolution gives better visuals but costs more memory (a pixel takes 4 bytes).

  • _grayscaleDefault: boolean = false

  • _invertedBackgroundDefault: boolean = false

  Returns DrawingApi<Change>
