- batgrl.texture_tools.composite(source: ndarray[tuple[int, int, Literal[4]], dtype[uint8]], dest: ndarray[tuple[int, int, Literal[4]], dtype[uint8]], pos: Point = (0, 0), mask_mode: bool = False) None#
Composite source texture onto destination texture at given position.
If mask_mode is true, source alpha values less than 255 are ignored.
- Parameters:
- sourceRGBA_2D
The texture to composite.
- destRGBA_2D
The texture on which the source is painted.
- posPointlike, default: Point(0, 0)
Position of the source on the destination.
- mask_modebool, default: False
Whether to ignore alpha values less than 255.
- batgrl.texture_tools.read_texture(path: Path) ndarray[tuple[int, int, Literal[4]], dtype[uint8]]#
Return a uint8 RGBA numpy array from a path to an image.
- Parameters:
- pathPath
Path to image.
- Returns:
- RGBA_2D
An uint8 RGBA array of the image.
- batgrl.texture_tools.resize_texture(texture: ndarray[tuple[int, int, Literal[4]], dtype[uint8]], size: Sizelike, interpolation: Literal['nearest', 'linear', 'cubic', 'area', 'lanczos'] = 'linear', out: ndarray[tuple[int, int, Literal[4]], dtype[uint8]] | None = None) ndarray[tuple[int, int, Literal[4]], dtype[uint8]]#
Resize texture.
- Parameters:
- textureRGBA_2D
An RGBA texture to resize.
- sizeSizelike
The new size of the texture.
- interpolationInterpolation, default: “linear”
Interpolation used when resizing texture.
- outRGBA_2D | None, default: None
Optional output array. If None, a new array is created.
- Returns:
- RGBA_2D
A new uint8 RGBA array.
