From c1ce2f7966babaae0deb150f93f1227ee5af9285 Mon Sep 17 00:00:00 2001 From: Brian Salomon Date: Thu, 1 Feb 2018 18:34:32 +0000 Subject: Revert "Redefine the meaning of sample counts in GPU backend." This reverts commit 48825b11ad25c98b9a4884d5cc0edd4e290c4409. Reason for revert: nanobench Original change's description: > Redefine the meaning of sample counts in GPU backend. > > Old: 0 -> nonMSAA > 1+ -> MSAA > > New: > 0 -> error/unsupported > 1 -> nonMSAA > 2+ -> MSAA > > We still allow 0 to mean nonMSAA in three sets of public APIs for backwards compatibility: > > 1) SkSurface factories > 2) GrBackendRenderTarget constructors > 3) GrCaps::getSampleCnt()'s requestedCount parameter > > However, we immediately clamp to 1 and treat 0 as invalid/non-renderable internally. > > This also changes the behavior when using a large sample count. We now fail in that case rather than using the largest sample available sample count. GrCaps::getSampleCount() will return 0 in this case. > > > Bug: skia: > Change-Id: Ida22c6b22c1365e563c9046b611e88bf5eb3ff33 > Reviewed-on: https://skia-review.googlesource.com/101560 > Reviewed-by: Greg Daniel > Commit-Queue: Brian Salomon TBR=egdaniel@google.com,bsalomon@google.com Change-Id: Ic257619a8a5ee9ac15419ecf10259e42daed7f82 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: skia: Reviewed-on: https://skia-review.googlesource.com/102662 Reviewed-by: Brian Salomon Commit-Queue: Brian Salomon --- include/private/GrRenderTargetProxy.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'include/private') diff --git a/include/private/GrRenderTargetProxy.h b/include/private/GrRenderTargetProxy.h index 1d5d8042ce..1cd3d5d1a2 100644 --- a/include/private/GrRenderTargetProxy.h +++ b/include/private/GrRenderTargetProxy.h @@ -26,7 +26,7 @@ public: bool instantiate(GrResourceProvider*) override; GrFSAAType fsaaType() const { - if (fSampleCnt <= 1) { + if (!fSampleCnt) { SkASSERT(!(fRenderTargetFlags & GrRenderTargetFlags::kMixedSampled)); return GrFSAAType::kNone; } @@ -50,7 +50,7 @@ public: * Returns the number of samples/pixel in the color buffer (Zero if non-MSAA or mixed sampled). */ int numColorSamples() const { - return GrFSAAType::kMixedSamples == this->fsaaType() ? 1 : fSampleCnt; + return GrFSAAType::kMixedSamples == this->fsaaType() ? 0 : fSampleCnt; } int maxWindowRectangles(const GrCaps& caps) const; -- cgit v1.2.3
