Parameters to create a stretch renderer based on output min/max pixel values.
Instances of this class represent parameters that can be used to create an AGSStretchRenderer
that applies a linear stretch based on the output minimum and output maximum pixel values which are used as the endpoints for the histogram.

- (NSArray<NSNumber *>*) maxValues |

readnonatomiccopy |
The maximum pixel value which serves as an endpoint for the histogram used for the stretch. All pixel values in the dataset greater than this value will be pushed to the maximum end of the histogram.
For example: Consider an 8-bit raster containing pixel values in the range from 33 to 206, and you've defined a max of 50 and min of 180. The histogram will be redistributed to spread the values from 0 to 255, all values 33 to 50 becoming 0 and 180 to 206 becoming 255, with all other values spread in between.
The array must contain a max value for each band in the raster, the 0th element for the 0th band, and so on.
