What Is a Clipping Path?

The path layer is mainly used in drawing. The concept is the same as when the warlords seized the land. The boundaries were delimited on the area. Within the boundaries are their own sites, and others cannot violate them. In VC ++, the BeginPath and EndPath functions provided by CDC are used to implement the path layer. BeginPath () is used to open a path layer in the device description table; then use the functions provided by the graphic device interface to perform drawing operations, such as drawing some points, ellipses, etc. Finally, after the drawing operation is completed, the application calls EndPath (). The function closes this path layer.
