Methods

`Make`	Creates an image filter that samples a region.
`__init__`

Methods

static AlphaThresholdFilter.Make(region: skia.Region, innerMin: float, outerMax: float, input: skia.ImageFilter = None, cropRect: skia.ImageFilter.CropRect = None) → skia.ImageFilter

Creates an image filter that samples a region.

If the sample is inside the region the alpha of the image is boosted up to a threshold value. If it is outside the region then the alpha is decreased to the threshold value. The 0,0 point of the region corresponds to the upper left corner of the source image.
