## DESCRIPTION

**SoPackedColor** is similar to **SoBaseColor** in that it sets the diffuse color component of the current material. However, it also changes the transparency component. The color and transparency information is packed into unsigned 32-bit integers: **0xrrggbbaa**, where **aa** represents the alpha (**0x00** = fully transparent, **0xff** = opaque), and **rr**, **gg**, and **bb** represent the red, blue, and green components of the color, respectively. Note that the order (r,g,b,a) of these components is reversed from the ordering in releases of Inventor prior to 2.1.

If the transparency type is **SoGLRenderAction::SCREEN\_DOOR**, only the first transparency value will be used. With other transparency types, multiple transparencies will be used.

**SoPackedColor** uses less memory than **SoBaseColor** or **SoMaterial** to store multiple color and transparency values. It can be used in cases where space is critical.

## FIELDS

**SoMFUInt32**	**orderedRGBA**\
 Defines the packed colors.

## METHODS

	**SoPackedColor()**\
 Creates a packed color node with default settings.

**static SoType**	**getClassTypeId()**\
 Returns type identifier for this class.

## ACTION BEHAVIOR

**SoGLRenderAction, SoCallbackAction**\
 Sets the current base (diffuse) color(s) in the state.

## FILE FORMAT/DEFAULTS

```
PackedColor {
orderedRGBA	0xccccccff
}
```
