1.1       root        1: Sample: PlgBlt Demonstration
                      2: 
                      3: Summary:
                      4: 
                      5: Win32 offers a new API function that will copy a bit image
                      6: onto an arbitrary parallelogram. Now, for the first time,
                      7: application programs can trivially rotate or shear bitmaps.
                      8: The PLGBLT SDK sample is an easy to use demonstration of how
                      9: this new API function may be used.
                     10: 
                     11: More Information:
                     12: 
                     13: The program presents a dialog box on top of the window that
                     14: displays the input parameters to the PlgBlt function. By
                     15: choosing the "New Src" or "New Mask" button, the user can
                     16: select a new bitmap for use as the source bitmap or as the
                     17: monochrome mask bitmap. The client area of the window is
                     18: divided into three regions. The region on the left contains
                     19: the result of the PlgBlt operation. The region in the middle
                     20: provides the source HDC, and the region on the right
                     21: provides the mask bitmap for the PlgBlt operation.
                     22: 
                     23: In each of the three regions, there is a "direct
                     24: manipulation object." This object may be picked up and moved
                     25: by clicking the left mouse button in the top-left corner and
                     26: dragging. The three objects are restricted in their response
                     27: to user actions to correctly reflect the parameters to the
                     28: PlgBlt function. The object in the mask region may be moved
                     29: only. The object in the source region may be moved or sized.
                     30: The object in the destination region may be moved, sized,
                     31: sheared, or rotated. Please see the WXFORM sample for more
                     32: information on how this direct manipulation is accomplished.
                     33: Additional information on the WXFORM sample may be obtained
                     34: by querying on the word WXFORM in this knowledge base.
