PICTURE PROCESSING METHOD AND ITS DEVICE

摘要

PURPOSE: To provide an image processing method and device which can display an unfixed-form image beautifully. CONSTITUTION: A working bit map is generated from a source bit map for a window where a bit map is displayed. Then a black-and-white mask for the source bit map is generated. Then a black-and-white inverted mask for the source bit map is generated. Further, a bit map is generated which has unfixed-form bit maps of the same background color with the window and black. A rectangular bit map is generated which has a black background and a unfixed-form bit map of an original color. The bit map is displayed in the window. Lastly, an unnecessary bit map and device context are deleted and display device context is released.
