virtual L_INT LAnnStamp::SetTransparent(bTransparent, uFlags=0)

Sets the bitmap associated with the Stamp object to use a transparent color. A transparent color is not painted when the image is painted.


L_BOOL bTransparent

Flag that indicates whether to make the bitmap transparent. Possible values are:

Value Meaning
TRUE Make the bitmap transparent.
FALSE Do not make the bitmap transparent. This is the default.

L_UINT uFlags

Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR ( | ). The following are valid values:

Value Meaning
0 Process only the specified object.
ANNFLAG_SELECTED [0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnotation::IsSelected and LAnnotation::SetSelected functions.
ANNFLAG_NOINVALIDATE [0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.


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


Only Point and Stamp objects that are using a bitmap can be set to use a transparent color. By default the transparent color is white (0x00FFFFFF). In order for the transparent bitmaps to be painted properly the LTEFXu.dll needs to be present for WIN32. If the appropriate DLL is not present, the transparent bitmap stamps will be painted as non-transparent bitmap stamps.

Required DLLs and Libraries


Win32, x64.
