Text i/o Using Device Contexts

  • Ian Chivers
Part of the Essential Series book series (ES)


This chapter looks at text i/o. We also look at device contexts. A device context is a structure that defines a set of graphic objects and their associated attributes, and the graphic modes that affect output. The graphic objects include:
  • A pen for line drawing.

  • A brush for painting and filling.

  • A bitmap for copying or scrolling parts of the screen.

  • A palette for defining the set of available colours.

  • A region for clipping and other operations.

  • A path for painting and drawing operations.
