Declaration
long MGLAPI MGL_divotSizeCoord(
MGLDC *dc,
int left,
int top,
int right,
int bottom)
Prototype In
mgraph.h
Parameters
dc |
Device context to measure divot size from |
left |
Left coordinate of divot area |
top |
Top coordinate of divot area |
right |
Right coordinate of divot area |
bottom |
Bottom coordinate of divot area |
Return Value
Size of the specified divot in bytes.
Description
Determines the number of bytes required to store a divot of the specified size taken from the current device context. A divot is a portion of video memory that needs to be temporarily saved and restored, such as implementing pull down menus and pop up dialog boxes. A divot must always be saved and restored to the same area, and will extend the dimensions of the area covered to obtain the maximum possible performance for saving and restoring the memory.
