virtual L_INT LBitmapBase::PointFromBitmap(nViewPerspective, px, py)
Translates a point (x,y) from the class object's bitmap view perspective to the specified view perspective.
Destination view perspective to which the point should be translated.
Address of variable for the X coordinate of the point.
Address of variable for the Y coordinate of the point.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
To use this function, do the following:
Declare variables for the X and Y coordinates of a point.
Assign the values of a known point in the bitmap.
Call this function, passing the addresses of the variables, and specifying the destination view perspective. (The function gets the source view perspective from the bitmap handle.)
Get the translated point from the variables, which this function has updated.
