Color QuickDraw Routines

Creating, Setting, and Disposing of Pixel Maps

QuickDraw automatically creates pixel maps when you create a color window with the GetNewCWindow or NewCWindow function (described in the chapter "Window Manager" in Inside Macintosh: Macintosh Toolbox Essentials), when you create offscreen graphics worlds with the NewGWorld function (described in the chapter "Offscreen Graphics Worlds" in this book), and when you use the OpenCPort function. QuickDraw also disposes of a pixel map when it disposes of a color graphics port. Although your application typically won't need to create or dispose of pixel maps, you can use the NewPixMap function and the CopyPixMap procedure to create them, and you can use the DisposePixMap procedure to dispose of them. Although you should never need to do so, you can also set the pixel map for the current color graphics port by using the SetPortPix procedure.
