virtual L_UINT LAnnAutomation::GetFillMode(puFillMode, pnAlpha)
NOTE: THIS FUNCTION IS NOW INHERITED DIRECTLY FROM THE PARENT LANNOTATION CLASS.
Gets the fill mode and alpha of the specified annotation object.
Pointer to a variable to be updated with the object's fill mode constant. Possible fill mode values are:
Value | Meaning |
---|---|
ANNMODE_TRANSPARENT | [0] Transparent |
ANNMODE_TRANSLUCENT | [1] Translucent |
ANNMODE_OPAQUE | [2] Opaque |
ANNMODE_ALPHA | [3] Alpha |
Pointer to a variable to be updated with the objects alpha value. This is only valid if the fill mode puFillMode is updated with is ANNMODE_ALPHA. Possible values range from 0 255 where:
Value | Meaning |
---|---|
0 | Transparent background. |
255 | Opaque background. |
The object's fill mode constant. Possible values are:
Value | Meaning |
