Retrieves a copy of the specified predefined bitmap.
#include "l_bitmap.h"
L_LTANN_API L_INT L_AnnGetPredefinedBitmap(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.
Size in bytes, of the structure pointed to by pBitmap
, for versioning. Use sizeof(BITMAPHANDLE).
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This function is valid only for the ANNOBJECT_POINT object. You must free the bitmap handle when you are finished, using L_FreeBitmap. Call the L_AnnSetPredefinedBitmap function to change or reset the predefined bitmap.
Win32, x64.
This example does the following:
L_INT AnnGetPredefinedBitmapExample()
{
BITMAPHANDLE PointBitmap;
L_INT nRet = SUCCESS;
// Get predefined point bitmap
nRet = L_AnnGetPredefinedBitmap(ANNBITMAP_POINT, &PointBitmap, sizeof(BITMAPHANDLE));
if (nRet != SUCCESS)
return nRet;
// Invert it
nRet = L_InvertBitmap(&PointBitmap, 0);
if (nRet != SUCCESS)
return nRet;
// Set as new point bitmap
nRet = L_AnnSetPredefinedBitmap(ANNBITMAP_POINT, &PointBitmap);
if (nRet != SUCCESS)
return nRet;
// Free the bitmap
L_FreeBitmap(&PointBitmap);
_tprintf(_T("%s"), TEXT("Now create a point annotation object. The bitmap is inverted"));
return SUCCESS;
}
