Typedef Documentation

SkXRect

typedef SkIRect SkXRect

Defines a fixed-point rectangle, identical to the integer SkIRect, but its coordinates are treated as SkFixed rather than int32_t.

Definition at line 24 of file SkScan.h.

Function Documentation

XRect_round()

static void XRect_round ( const SkXRect &  xr, SkIRect *  dst  )

inlinestatic

Round the SkXRect coordinates, and store the result in the SkIRect.

Definition at line 118 of file SkScan.h.

                                                                {
    dst->fLeft = SkFixedRoundToInt(xr.fLeft);
    dst->fTop = SkFixedRoundToInt(xr.fTop);
    dst->fRight = SkFixedRoundToInt(xr.fRight);
    dst->fBottom = SkFixedRoundToInt(xr.fBottom);
}

XRect_roundOut()

static void XRect_roundOut ( const SkXRect &  xr, SkIRect *  dst  )

inlinestatic

Round the SkXRect coordinates out (i.e. use floor for left/top, and ceiling for right/bottom), and store the result in the SkIRect.

Definition at line 128 of file SkScan.h.

                                                                   {
    dst->fLeft = SkFixedFloorToInt(xr.fLeft);
    dst->fTop = SkFixedFloorToInt(xr.fTop);
    dst->fRight = SkFixedCeilToInt(xr.fRight);
    dst->fBottom = SkFixedCeilToInt(xr.fBottom);
}

XRect_set() [1/2]

static void XRect_set ( SkXRect *  xr, const SkIRect &  src  )

inlinestatic

Assign an SkXRect from a SkIRect, by promoting the src rect's coordinates from int to SkFixed. Does not check for overflow if the src coordinates exceed 32K

Definition at line 98 of file SkScan.h.

                                                              {
    xr->fLeft = SkIntToFixed(src.fLeft);
    xr->fTop = SkIntToFixed(src.fTop);
    xr->fRight = SkIntToFixed(src.fRight);
    xr->fBottom = SkIntToFixed(src.fBottom);
}

XRect_set() [2/2]

static void XRect_set ( SkXRect *  xr, const SkRect &  src  )

inlinestatic

Assign an SkXRect from a SkRect, by promoting the src rect's coordinates from SkScalar to SkFixed. Does not check for overflow if the src coordinates exceed 32K

Definition at line 109 of file SkScan.h.

                                                             {
    xr->fLeft = SkScalarToFixed(src.fLeft);
    xr->fTop = SkScalarToFixed(src.fTop);
    xr->fRight = SkScalarToFixed(src.fRight);
    xr->fBottom = SkScalarToFixed(src.fBottom);
