PV Index to color


PV Index to color ( index ) -> Function result

Parameter	Type	Description
index	Integer	Indexed color number
Function result	Longint	Color number

Description

The PV Index to color command returns the corresponding RGB color number, in the 4D palette, to the number index.

The three RGB components can later be extracted from this result using the PV COLOR TO RGB command.

For the index parameter, you can use the constants of the 4D language found in the Colors theme, available for the first 16 colors (row 1 of the palette which includes 256).

Refer to the descriptions of the following 4D commands for detailed information on the colors used by 4D:

OBJECT SET RGB COLORS for the RGB color system used by 4D.
OBJECT SET COLOR for the 4D color palette.

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

Refer to the examples for the PV SET RANGE BORDER and PV Color to index commands.
