virtual L_INT LAnnContainer::SetTransparent(bTransparent, uFlags=0)
L_BOOL bTransparent; |
flag that indicates whether to make the bitmap transparent |
L_UINT uFlags; |
flags that determine which objects to process |
Sets one or more bitmap stamp objects to use white as a transparent color.
Parameter | Description | |
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. | |
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_NOTTHIS | [0x0004] Process only one level of objects within the specified container, not the container itself. If there are containers within the container, they are modified, but the objects within them are not. | |
ANNFLAG_RECURSE | [0x0008] Process objects within a container, and within any subcontainers, down to any level. | |
ANNFLAG_NOTCONTAINER | [0x0002] (Used with ANNFLAG_RECURSE) Process objects within containers, not the containers themselves. | |
ANNFLAG_NOINVALIDATE | [0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages. |

Only bitmap stamps can be transparent. In transparent stamps, all the white pixels are considered transparent. In order for the transparent bitmaps to be painted properly, the LTEFX15u.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.
