---|---|---|---|---|---|---|---|---|---|---|---|---|---|
This argument must reference a spreadsheet cell containing a Hist or ColorHist data structure. |
|||||||||||||
Specifies the first "bin" (0 to 255; default = 0) used to define the histogram. For more information, see What is a Histogram?. |
|||||||||||||
Specifies the last "bin" (0 to 255; default = 255) used to define the histogram. For more information, see What is a Histogram?. |
|||||||||||||
Specifies the index of the color component's histogram from a ColorHist data structure (default = 0). Note: The Color parameter is optional and only available when connected to a color In-Sight vision system, and will be ignored if a Hist structure is referenced in the Structure parameter. When connected to a color vision system, if the Structure parameter references a ColorHist
structure (output by an ExtractColorHistogram
function), the Color parameter can be used to select the color
component. For more information, see ExtractColorHistogram or Color Components of a Pixel.
