SVG_SET_BRIGHTNESS ( svgObject ; brightness {; brightness2 ; brightness3} )
| Parameter | Type | Description | |
|---|---|---|---|
| svgObject | SVG_Ref | → | SVG object reference |
| brightness | Real | → | Values between 0 and 1 to darken; > 1 to brighten, applied globally or only to red component |
| brightness2 | Real | → | Brightness value for green component |
| brightness3 | Real | → | Brightness value for blue component |
The SVG_SET_BRIGHTNESS command sets the brightness for an SVG image or container whose reference is passed in the svgObject parameter.
In the brightness parameter, you pass either a value between 0 and 1 to darken the brightness, or a value greater than 1 to brighten it. When you pass a single brightness parameter, the brightness factor is applied globally to the object.
Alternatively, you can pass two additional (optional) brightness2 and brightness3 parameters, in which case each brightness value is applied to a separate part of the color component, i.e. brightness is applied to the “R” (red) part, brightness2 is applied to the “G” (green) part and brightness3 is applied to the “B” (blue) part.
