Am I using SampleMapRenderer incorrectly or missing something? I'm getting CyclicGraphExceptions but I don't see what the problem could be. Here's the code: private static IDeviceImage SampleAt(IDeviceContext dc, IDeviceImage src, float offsetX, float offsetY) { IDeviceImage sm = new HlslBinaryOperatorEffect(dc, new ScenePositionEffect(dc, ScenePositionFormat.XY01), HlslBinaryOperator.Add, new Vector4Float(offsetX, offsetY, 0f, 0f)); SampleMapRenderer r = new SampleMapRenderer(dc); r.Properties.Input.Set(src); r.Properties.SampleMaps.SetCount(1); r.Properties.SampleMaps[0].Set(sm); r.Properties.EdgeMode.SetValue(SampleMapEdgeMode.Clamp); r.Properties.SamplingMode.SetValue(SampleMapSamplingMode.Linear); return r; } protected override IDeviceImage OnCreateOutput(IDeviceContext dc) { IDeviceImage src = Environment.SourceImage; //IDeviceImage sX1 = SampleAt(dc, src, -0.25f, 0f), sX2 = SampleAt(dc, src, 0.25f, 0f); return new HlslBinaryOperatorEffect(dc, new HlslBinaryFunctionEffect(dc, HlslBinaryFunction.Dot, sX1, sX1), HlslBinaryOperator.Subtract, new HlslBinaryFunctionEffect(dc, HlslBinaryFunction.Dot, sX2, sX2)); // Doesn't help return new HlslBinaryOperatorEffect(dc, new HlslBinaryFunctionEffect(dc, HlslBinaryFunction.Dot, SampleAt(dc, src, -0.25f, 0f), SampleAt(dc, src, -0.25f, 0f)), HlslBinaryOperator.Subtract, new HlslBinaryFunctionEffect(dc, HlslBinaryFunction.Dot, SampleAt(dc, src, +0.25f, 0f), SampleAt(dc, src, +0.25f, 0f))); }

Hi, I get a 100% reproducible crash of paint.net when typing the indicated dot '.' in the following code snippet in CodeLab 6.8: Rectangle[] rois = selectionRegion.GetRegionScansInt(); int roisLength = rois. // 👈 typing that '.' immediately crashes paint.net //gaussianblurEffect.Render(gaussianblurParameters, auxArgs, wrkArgs, selectionRegion); gaussianblurEffect.Render(gaussianblurParameters, auxArgs, wrkArgs, rois, 0, roisLength); The dot '.' has to be typed for the crash to occur, simply copy-pasting the snippet doesn't trigger the crash as the crash occurs while populating the list of available code completion suggestions.
