SkPaint paint;
paint.setImageFilter(SkBlurImageFilter::Create(fSigmaX, fSigmaY))->unref();
canvas->saveLayer(nullptr, &paint);
const char* str = "The quick brown fox jumped over the lazy dog.";
SkRandom rand;
SkPaint textPaint;
textPaint.setAntiAlias(true);
sk_tool_utils::set_portable_typeface(&textPaint);
for (int i = 0; i < 25; ++i) {
int x = rand.nextULessThan(WIDTH);
int y = rand.nextULessThan(HEIGHT);
textPaint.setColor(sk_tool_utils::color_to_565(rand.nextBits(24) | 0xFF000000));
textPaint.setTextSize(rand.nextRangeScalar(0, 300));
canvas->drawText(str, strlen(str), SkIntToScalar(x),
SkIntToScalar(y), textPaint);
}
canvas->restore();
