LAnnPoint::GetPredefinedBitmap

Summary

Retrieves a copy of the specified predefined bitmap.

Syntax

#include "ltwrappr.h"

static L_INT LAnnPoint::GetPredefinedBitmap(uType, pBitmap, uStructSize)

Parameters

L_UINT uType

Value that indicates the bitmap to retrieve. Possible values are:

Value	Meaning
ANNBITMAP_POINT	[0] Predefined metafile for annotation point object.

pBITMAPHANDLE pBitmap

Pointer to a variable to be updated with the bitmap handle.

LBitmapBase * pBitmap

Pointer to a valid bitmap object containing the image to set.

L_UINT uStructSize

Size in bytes, of the structure pointed to by pBitmap. Use sizeof(BITMAPHANDLE).

Returns

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

Comments

You must free the bitmap handle when you are finished, using the LBitmapBase::Free function. Call the LAnnPoint::SetPredefinedBitmap function to change or reset the predefined bitmap.

Example

This example does the following:

Gets the current point bitmap
Inverts it

Sets the inverted bitmap as the default point bitmap

L_INT LAnnPoint_GetPredefinedBitmapExample() 
{ 
	L_INT nRet; 
   LBitmap PointBitmap;  
 
   // Get predefined point bitmap 
   nRet = LAnnPoint::GetPredefinedBitmap(ANNBITMAP_POINT, &PointBitmap, sizeof(BITMAPHANDLE));  
	if(nRet != SUCCESS) 
		return nRet; 
 
   // Invert it 
   nRet = PointBitmap.Invert(); 
	if(nRet != SUCCESS) 
		return nRet; 
 
   // Set as new point bitmap 
   nRet = LAnnPoint::SetPredefinedBitmap (ANNBITMAP_POINT, &PointBitmap);  
	if(nRet != SUCCESS) 
		return nRet; 
   MessageBox(NULL, TEXT("Now create a point annotation object.  The bitmap is inverted"), TEXT(""), MB_OK);  
	 
	return SUCCESS;
