RGB (Function)

In french: RVB

Defines a color from its Red, Green and Blue components.

Example

// Color an area in light blue
dFill(10, 50, RGB(0, 255, 255))

Syntax

<Result> = RGB(<Red component> , <Green component> , <Blue component>)

<Result>: Integer

Color (24 bits) corresponding to the selected components. This color is the result of the following formula:
Color = 65536 * Blue Component + 256 * Green Component + Red Component.
The color is returned in the format of a character string by the browser.

<Red component>: Integer (from 0 to 255)

Amount of red in the color.

<Green component>: Integer (from 0 to 255)

Amount of green in the color.

<Blue component>: Integer (from 0 to 255)

Amount of blue in the color.

Remarks

HTML colors

In an HTML page, the colors are represented by a character string such as "#RRGGBB". RR, GG and BB represent the hexadecimal value of red, green and blue components.

The following code allows you to convert an HTML color into an RGB color:

nRGB is int
HTMLColor is string
// If the HTML color has no #
nRGB = RGB(Val(Left(HTMLColor, 2), "x"), ...
Val(Middle(HTMLColor, 3, 2), "x"), ...
Val(Right(HTMLColor, 2), "x"))
// If the HTML color contains #
nRGB = RGB(Val(Middle(HTMLColor, 2, 2), "x"), ...
Val(Middle(HTMLColor, 4, 2), "x"), ...
Val(Right(HTMLColor, 2), "x"))
