Field Summary

Fields

Modifier and Type	Field	Description
static int	PADDING_FILL_BLUR_CROP	Padding introduced by fit scale type is filled by first rendering the current stream frame using crop scale type, blurred, then overlaying the scaled frame on top of it.
static int	PADDING_FILL_BLUR_EXTEND	Padding introduced by fit scale type is filled by repeating current frame borders, blurred.
static int	PADDING_FILL_NONE	Padding introduced by fit scale type is filled with default reset color.
static int	SCALE_TYPE_CROP	Scales the stream so that its smallest dimension spans the whole view; its largest dimension is scaled accordingly to respect original aspect ratio, and cropped to the render zone; no padding is introduced.
static int	SCALE_TYPE_FIT	Scales the stream so that its largest dimension spans the whole view; its smallest dimension is scaled accordingly to respect original aspect ratio, centered in the render zone; introduced padding, if any, is rendered according to padding fill configuration.
