int Histgram(
        const IMAGE     *image,
        const BYTE      *model,
        const int       *num,
        int             *nep,
        int             **histgram
)

Parameters

*image	Image data structure address
*model	Model data
*num	Plane number
*nep	Number of valid pixels (measurement result)
**histgram	Histogram storage space (measurement result)

Return Value

NORMAL(0): Successful completion

ERROR(-1): Unsuccessful completion

Description

Performs the histogram measurement of an arbitrary area with the specified parameters.

For the histogram storage space, you need to allocate a space where the frequencies for 256 shades can be stored.

(example: for RGB color int histgram[3][num];)

For monochrome

histgram[0][]

Monochrome histogram

For RGB color

histgram[0][]

R density histogram

histgram[1][]

G density histogram

histgram[2][]

B density histogram
