public class TLcdSLDNormalize
extends TLcdDataObject

Represents a Normalize contrast enhancement operation, applicable to raster data styling.

The following vendor options can be specified to configure the values of the normalization interval:

• minValue: defines the minimum value of the normalization interval. By default, 0 is used.
• maxValue: defines the maximum value of the normalization interval. By default, the max bit depth is used.

If only one of these values is defined, a default value is used for the other: 0 for minValue and the max bit depth for maxValue.

If no minimum / maximum values are defined, a histogram is used to automatically deduce them from the source image. This histogram is an approximation, using a maximum image size of 2048 x 2048 (if the image is larger, it is cropped around the middle) and 1024 bins. Additionally, a cumulative count cut filter is applied to remove outliers outside the 2% - 98% interval.

Since:

2018.1
