AGSPercentClipStretchParameters Class Reference

Description

Parameters to create a stretch renderer based on percentile min/max pixel values.

Instances of this class represent parameters that can be used to create an AGSStretchRenderer object that applies a linear stretch between the percentile minimum and maximum pixel values defined.

initWithMin:max:

- (instancetype) initWithMin:		(double)	min
max:		(double)	max

Initializes the parameters with the provided values.

Parameters

min	Percentile cutoff below which values in the raster dataset are to be clipped. Valid values are 0 - 100.
max	Percentile cutoff above which pixel values in the raster dataset are to be clipped. Valid values are 0 - 100.

Parameters

min	Percentile cutoff below which values in the raster dataset are to be clipped. Valid values are 0 - 100.
max	Percentile cutoff above which pixel values in the raster dataset are to be clipped. Valid values are 0 - 100.

Returns

Percentile cutoff above which pixel values in the raster dataset are to be clipped. Valid values are 0 - 100.

For example: Consider an 8-bit raster containing pixel values in the range from 33 to 206, and you've defined a percent clip minimum and maximum of 2. If 2 percent at the low end is values 33 to 45 and 2 percent at the high end is 198 to 206, the histogram will be redistributed to spread the values from 0 to 255, all values 33 to 45 becoming 0 and 198 to 206 becoming 255, with all other values spread in between.
