Should we add a 'kInitStyleCount ' ?

[joshualitt, 2015/05/07 21:22:39]

Well, there is a macro which Mike Klein made to make auto counting enums. 
Otherwise, I'd rather not add a count.

+            SkStrokeRec::InitStyle(random->nextULessThan(SkStrokeRec::kFill_InitStyle + 1));
+    SkStrokeRec rec(style);
+    bool strokeAndFill = random->nextBool();

A width one too? Maybe 10?

[joshualitt, 2015/05/07 21:22:39]

you want me to make an enum of possible widths with 10 values?  I want to be
careful playing with the width because some of the renderers expect strokewidth
to be sane relative to the geometry they draw.

[robertphillips, 2015/05/08 12:02:07]

I was just angling for a wider one (i.e., a stroke width of 10) but it sounds
like that could cause problems.

+    SkScalar strokeWidth = random->nextBool() ? 0.f : 1.f;
+    rec.setStrokeStyle(strokeWidth, strokeAndFill);
+
+    SkPaint::Cap cap = SkPaint::Cap(random->nextULessThan(SkPaint::kCapCount));
+    SkPaint::Join join = SkPaint::Join(random->nextULessThan(SkPaint::kJoinCount));
+    SkScalar miterLimit = random->nextRangeScalar(1.f, 5.f);
+    rec.setStrokeParams(cap, join, miterLimit);
+    return rec;
+}
+
 };
