maskFilter property
A mask filter (for example, a blur) to apply to a shape after it has been drawn but before it has been composited into the image.
See MaskFilter for details.
Implementation
MaskFilter get maskFilter {
switch (_data.getInt32(_kMaskFilterOffset, _kFakeHostEndian)) {
case MaskFilter._TypeNone:
return null;
case MaskFilter._TypeBlur:
return MaskFilter.blur(
BlurStyle.values[_data.getInt32(_kMaskFilterBlurStyleOffset, _kFakeHostEndian)],
_data.getFloat32(_kMaskFilterSigmaOffset, _kFakeHostEndian),
);
}
return null;
}
Implementation
set maskFilter(MaskFilter value) {
if (value == null) {
_data.setInt32(_kMaskFilterOffset, MaskFilter._TypeNone, _kFakeHostEndian);
_data.setInt32(_kMaskFilterBlurStyleOffset, 0, _kFakeHostEndian);
_data.setFloat32(_kMaskFilterSigmaOffset, 0.0, _kFakeHostEndian);
} else {
// For now we only support one kind of MaskFilter, so we don't need to
// check what the type is if it's not null.
_data.setInt32(_kMaskFilterOffset, MaskFilter._TypeBlur, _kFakeHostEndian);
_data.setInt32(_kMaskFilterBlurStyleOffset, value._style.index, _kFakeHostEndian);
_data.setFloat32(_kMaskFilterSigmaOffset, value._sigma, _kFakeHostEndian);
}
