Sharpen Raster Image

PARAMETER

s

Purpose

This parameter defines a factor for sharpening the content of raster images. If a positive sharpening factor is defined then the raster image will have edge detection algorithms applied to sharpen the contrast between lines and the image background. A negative value will result in a blurrier image.

Range

Valid values range from -2000 (very blurry) to 2000 (high contrast). A value of 0 (or no value) will result in no sharpening being done.

Example

-s 1000

Use

With all raster formats
