inplace = truefalse

Specifies whether the operation is performed in-place. This can be used to avoid allocating memory. The default is false.

output = Image

Specifies a data structure into which the output is written. This can be used to avoid allocating memory. The size and number of layers must match that of the input. The dimensions of the output image are adjusted so that the row and column indices match the input. The default is NULL.

The RGBtoHSV command converts a color image with an RGB color representation to an HSV color representation.

The img parameter is the input image and must be of type ColorImage or ColorAImage.
