示例1: just_trans_clamp
/**
* For the purposes of drawing bitmaps, if a matrix is "almost" translate
* go ahead and treat it as if it were, so that subsequent code can go fast.
*/
static bool just_trans_clamp(const SkMatrix& matrix, const SkPixmap& pixmap) {
SkASSERT(matrix_only_scale_translate(matrix));
if (matrix.getType() & SkMatrix::kScale_Mask) {
SkRect dst;
SkRect src = SkRect::Make(pixmap.bounds());
// Can't call mapRect(), since that will fix up inverted rectangles,
// e.g. when scale is negative, and we don't want to return true for
// those.
matrix.mapPoints(SkTCast<SkPoint*>(&dst),
SkTCast<const SkPoint*>(&src),
2);
// Now round all 4 edges to device space, and then compare the device
// width/height to the original. Note: we must map all 4 and subtract
// rather than map the "width" and compare, since we care about the
// phase (in pixel space) that any translate in the matrix might impart.
SkIRect idst;
dst.round(&idst);
return idst.width() == pixmap.width() && idst.height() == pixmap.height();
}
// if we got here, we're either kTranslate_Mask or identity
return true;
}
