ImgEvaluateChromaticity

Prototype

intChormaticity:=ImgEvaluateChromaticityFocus(intImageHandle)

Description

Evaluates if the content of an image is black and white, grayscale or color.

Parameters

intImageHandle: integer value corresponding to the image handle.

Returned value

Integer value representing the image chromaticity: 0 = empty, 1 = bitonal, 2 = grayscale, 3 = color.

Notes

Don't confuse chromaticity with bits per pixel! A bitonal image can be acquired also at 24 bits per pixel (true-color), but still its chromaticity its bitonal.

Example

// Find the focus level

Chromaticity:=ImgEvaluateChromatcitiy(_CurrentImage);

// Log a message 

ApplicationLog('Image chromaticity is '+IntToStr(Chromaticity))
