Description

The PV COLOR TO RGB command returns, in the red, green and blue parameters, the three RGB components of color.

Refer to the description of the 4D OBJECT SET RGB COLORS command for detailed information on the color system used by 4D.

Note: Internal coding of 4D View colors is of the BGR type, which is reversed with respect to 4D's RGB coding; however, the principles of use are the same.

Example

Display the three RGB components of the background color of cell A1:

 C_LONGINT($Color)

 C_LONGINT($Red;$Green;$Blue)

 

 PV SET CELL STRING VALUE(Area;2;1;"Color") //Labels

 PV SET CELL STRING VALUE(Area;2;2;"Red")

 PV SET CELL STRING VALUE(Area;2;3;"Green")

 PV SET CELL STRING VALUE(Area;2;4;"Blue")

 

 $Color:=PV Get cell property(Area;1;1;pv style color back odd)

 PV COLOR TO RGB($Color;$Red;$Green;$Blue)

 

 PV SET CELL NUM VALUE(Area;1;2;$Red) //Values

 PV SET CELL NUM VALUE(Area;1;3;$Green)

 PV SET CELL NUM VALUE(Area;1;4;$Blue)
