L_AnnPrint

#include "l_bitmap.h"

L_LTANN_API L_INT L_AnnPrint(hDC, prcBounds, hObject)

Prints the specified annotation object, fitting it to a bounding rectangle in the specified device context.

Parameters

HDC hDC

Handle to the device context (DC) where the annotation is to print. The mapping mode of the device context must be MM_TEXT.

LPRECT prcBounds

Pointer to the Windows RECT structure that defines the bounding rectangle where this function will fit the annotation for printing. To maintain the aspect ratio, this rectangle should have the same proportions as the annotation object that you are printing.

HANNOBJECT hObject

Handle to the annotation object to print. If you specify a container object, all visible objects in the container will print.

Returns

Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.

Required DLLs and Libraries

Platforms

Win32, x64.

Example

For complete sample code, refer to the ANNOTATE example. This example prints a bitmap and its annotations.
