TableMaskFilter

class TableMaskFilter

Applies a table lookup on each of the alpha values in the mask.

Helper methods create some common tables (e.g. gamma, clipping)

Methods

Create	Create(table: list[int]) -> skia.MaskFilter
CreateClip	CreateClip(min: int, max: int) -> skia.MaskFilter
CreateGamma	CreateGamma(gamma: float) -> skia.MaskFilter
MakeClipTable	MakeClipTable(min: int, max: int) -> object
MakeGammaTable	MakeGammaTable(gamma: float) -> object
__init__

Methods

static TableMaskFilter.Create(table: list[int]) → skia.MaskFilter

static TableMaskFilter.CreateClip(min: int, max: int) → skia.MaskFilter

static TableMaskFilter.CreateGamma(gamma: float) → skia.MaskFilter

static TableMaskFilter.MakeClipTable(min: int, max: int) → object

Utility that creates a clipping table: clamps values below min to 0 and above max to 255, and rescales the remaining into 0..255.

Returns:

clipping table

Return type:

List[int]

static TableMaskFilter.MakeGammaTable(gamma: float) → object

Utility that sets the gamma table.

Returns:

gamma table

Return type:

List[int]
