toGray16

toGray16 ( integer Input, integer Output [, integer Min=0, integer Max=0] )

Use this function to convert an image or selection into a 16-bit high-depth grayscale format.

Parameters

Input

An integer between 0 and 116 specifying the input image frame number. A value of 0 represents the DMA memory buffer of the video device. Values in the range of 100-116 correspond to hidden frames.

Output

An integer between 1 and 116 specifying the output image frame number. Values in the range of 100-116 correspond to hidden frames.

Min, Max

Optional integers that represent the luminance range of the output image's pixels. Performing the conversion, ImageWarp will stretch the display range of the input image to the minimal and maximal values specified by these parameters. If both Min and Max are zero or omitted, the display range of the input image will be mapped to the pixel value range of 0 – 65535.

Default values: 0
