scale_max ( Image : ImageScaleMax : : )

Maximum gray value spreading in the value range 0 bis 255.

The operator scale_max calculates the minimum and maximum and scales the image to the maximum value range of a byte image. This way the dynamics (value range) is fully exploited. The number of different gray scales does not change, but in general the visual impression is enhanced. The gray values of images of the real and int2 type are scaled to the range 0 to 255 and returned as byte images.


Attention

The output always is an image of the type byte.


Parameters

Image (input_object)
image(-array) -> object : byte / int2 / real
Image to be scaled.

ImageScaleMax (output_object)
image(-array) -> object : byte
contrast enhanced image.
