# pmVersion

The version number of Color QuickDraw that created this PixMap structure. The value of pmVersion is normally 0. If pmVersion is 4, Color QuickDraw treats the PixMap record's baseAddr field as 32-bit clean. All other flags are private. Most applications never need to set this field

## Declaration

```swift
var pmVersion: Int16
```
