Synopsis

Header: fxcg/display.h
Syscall index: 0x02B2
Function signature: void Bdisp_AreaClr( TBdispFillArea* area, unsigned char target, unsigned short color)

Performs a VRAM or DD operation to fill an area with a color, depending on the mode of area.

Parameters

  • TBdispFillArea* area - area to fill and mode
  • unsigned char target - where to perform the operation, VRAM or DD.

If bit target.0 is set, the function performs a VRAM-operation. If bit target.1 is set, the function performs a DD-operation.

  • unsigned short color - color that will be used to fill when certain modes are used
struct TBdispFillArea {
    int x1;
    int y1;
    int x2;
    int y2;
    unsigned char mode;
};

  • unsigned char mode - if 0, area is filled white; if 1, area is filled with color, if 2, area is shaded with color; if 4, area will be inverted (may be a bug).
