SUMMARY
PicClip.exe is a sample that demonstrates how to use an ActiveX PictureClip control to select an area from a source bitmap and display the image in an ActiveX FoxHWND control (FoxHWND.ocx). By using the PictureClip control (PicClp32.ocx), the user can select a specific area from a source bitmap as an object that can then be passed to another control that is capable of accepting an object reference.

The PictureClip control provides an efficient mechanism for storing multiple picture resources in a single bitmap file. Instead of using multiple bitmaps or icons, you need to create a source bitmap that contains all of the bitmap images that are required by your application. When you need to display an individual bitmap, use the PictureClip control to select the region in the source bitmap that contains the portion of the bitmap that you need.

You can specify the clipping region in the source bitmap in one of two ways:
 * Select any portion of the source bitmap as the clipping region. Specify the upper-left corner of the clipping region by using the ClipX and ClipY properties. Specify the area of the clipping region by using the ClipHeight and ClipWidth properties. This method is useful when you want to view a random portion of a bitmap.
 * Divide the source bitmap into a specified number of rows and columns. The result is a uniform matrix of picture cells numbered 0, 1, 2, and so on. You can then display individual cells by using the GraphicCell property. This method is useful when the source bitmap contains a palette of icons that you want to display individually, such as in a toolbar bitmap.

Because the PictureClip control returns an object rather than a Bitmap, an image control cannot be used to display the selected area of the source bitmap. To display the selected area of the source bitmap, use a FoxHWND control to accept and display the object.
