NIH Image

Loads the default grayscale look-up table. The contrast and brightness of grayscale images can be adjusted by direct manipulation of the transformation function displayed in the Map window. This function can be applied to the pixel data in memory, thereby making contrast and brightness changes permanent, using the Apply LUT command. The Grayscale command will not convert 8-bit true color (as opposed to pseudocolor) images to grayscale. Instead, use the Convert to Grayscale variation of the Apply LUT command.
