The Default View Device Object
When you first create a view device object, you must assign it to a specific view group, and you must give it a reference to a bitmap shape--which you have set up--that describes the size, pixel depth, and location of the device's imaging area. Otherwise, the view device has these default properties:
For view devices that you do not create, QuickDraw GX defines their properties to be consistent with the physical devices they represent. See "View Device Objects and Physical Devices" (next).
- A clip shape that is a full shape. The clip has no effect.
- A mapping that is the identity mapping. This means that the upper left corner of the imaging area is at (0.0, 0.0) in global space, and the device resolution is 72 pixels per inch.
- No attributes set.
- An empty tag list.
