The LChange class is derived from LBase. This class provides support for changing between LEAD bitmap objects and device dependent bitmaps (DDB) and device independent bitmaps (DIB). Unlike the DIB and DDB conversion functions of LBitmapBase, these functions do not result in 2 copies of the image being in memory after the function is complete. These functions will invalidate the source image, and result in only one copy after function completion.
When calling some functions of the LBitmapBase LEADTOOLS C++ Class Library classes, the bitmap data is changed. To be notified of these changes, you can override the LBitmapBase::StartChanging and LBitmapBase::EndChanging functions. For more information, refer to Bitmap Change Notifications and Notification Categories.
Required Libraries
You must load all required libraries using LBase::LoadLibraries before using the classes.
