clipRect method Null safety
Reduces the clip region to the intersection of the current clip and the given rectangle.
If doAntiAlias
is true, then the clip will be anti-aliased.
If multiple draw commands intersect with the clip boundary, this can result in incorrect blending at the clip boundary. See saveLayer for a discussion of how to address that.
Use ClipOp.difference to subtract the provided rectangle from the current clip.
Implementation
void clipRect(Rect rect, { ClipOp clipOp = ClipOp.intersect, bool doAntiAlias = true }) {
assert(_rectIsValid(rect));
assert(clipOp != null);
assert(doAntiAlias != null);
_clipRect(rect.left, rect.top, rect.right, rect.bottom, clipOp.index, doAntiAlias);
}
