From c490f801b063a0837501feab3d12b73d71f46312 Mon Sep 17 00:00:00 2001 From: "jvanverth@google.com" Date: Mon, 4 Mar 2013 13:56:38 +0000 Subject: Change random number generator for 'tests' to SkMWCRandom. Also removes some unused headers and fixes a couple of bugs exposed by changing the random number generator: First, the function SkMatrix::getMaxStretch() had an error where it was testing the square of a number against near-zero. This led to it occasionally taking a cheaper but imprecise path for computing the eigenvalues of the matrix. It's been replaced with a check against the square of SK_ScalarNearlyZero. The second case was a failure in ClipStackTest, where it hit the rare case of a practically empty clip stack (it has a single Union) and we set a tight bounds. The bounds rect doesn't get set by GrReducedClip::ReduceClipStack() in this case, so when it clips the reduced stack it's clipping against garbage, and the resulting regions don't match. The solution is to initialize the tightBounds rect. git-svn-id: http://skia.googlecode.com/svn/trunk@7952 2bbb7eff-a529-9590-31e7-b0007b416f81 --- tests/PackBitsTest.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'tests/PackBitsTest.cpp') diff --git a/tests/PackBitsTest.cpp b/tests/PackBitsTest.cpp index f7d4b8e6b1..59c8a8cab9 100644 --- a/tests/PackBitsTest.cpp +++ b/tests/PackBitsTest.cpp @@ -14,7 +14,7 @@ static const uint16_t gTest2[] = { 0, 0, 0, 1, 2, 3, 3, 3 }; static const uint16_t gTest3[] = { 0, 0, 0, 0, 0, 0, 1, 2, 3, 3, 3, 0, 0, 1 }; #include "SkRandom.h" -static SkRandom gRand; +static SkMWCRandom gRand; static void rand_fill(uint16_t buffer[], int count) { for (int i = 0; i < count; i++) buffer[i] = (uint16_t)gRand.nextU(); -- cgit v1.2.3
