Retrieves a copy of the specified predefined bitmap.
#include "ltwrappr.h"
static L_INT LAnnPoint::GetPredefinedBitmap(uType, pBitmap, uStructSize)
static L_INT LAnnPoint::GetPredefinedBitmap(uType, pBitmap, uStructSize)
Value that indicates the bitmap to retrieve. Possible values are:
Value | Meaning |
---|---|
ANNBITMAP_POINT | [0] Predefined metafile for annotation point object. |
Pointer to a variable to be updated with the bitmap handle.
Pointer to a valid bitmap object containing the image to set.
Size in bytes, of the structure pointed to by pBitmap. Use sizeof(BITMAPHANDLE).
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
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.
Win32, x64.
This example does the following:
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;
}
