He proposed to just replace < by <= in line 78, but that would only shift the problem to values > 1. Those values should not be used from a semantic point, but it's not forbidden in a float value. My fix here keeps the <, but adds an else path that uses the original value from scanline[i]. This adds an else to the code (which technically adds a jump after the then-part), but omits the multiplication. The simple solution @tocsoft proposed might be faster, but should be preferred if and only if BlendPercentage can be guaranteed to be <=1. --- .../Processing/Drawing/Brushes/BrushApplicator.cs | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/src/ImageSharp.Drawing/Processing/Drawing/Brushes/BrushApplicator.cs b/src/ImageSharp.Drawing/Processing/Drawing/Brushes/BrushApplicator.cs index f665e8408c..c546663353 100644 --- a/src/ImageSharp.Drawing/Processing/Drawing/Brushes/BrushApplicator.cs +++ b/src/ImageSharp.Drawing/Processing/Drawing/Brushes/BrushApplicator.cs @@ -79,6 +79,10 @@ namespace SixLabors.ImageSharp.Processing.Drawing.Brushes { amountSpan[i] = scanline[i] * this.Options.BlendPercentage; } + else + { + amountSpan[i] = scanline[i]; + } overlaySpan[i] = this[x + i, y]; } From 4b92801e3384e0c861d7ed2b622fd2aa15c82a63 Mon Sep 17 00:00:00 2001 From: Unknown Date: Fri, 20 Apr 2018 00:01:33 +0200 Subject: [PATCH 004/118] #542: fix test: indices are 0-based, so bottom left pixel is one smaller --- .../Drawing/FillLinearGradientBrushTests.cs | 20 ++++++++----------- 1 file changed, 8 insertions(+), 12 deletions(-) diff --git a/tests/ImageSharp.Tests/Drawing/FillLinearGradientBrushTests.cs b/tests/ImageSharp.Tests/Drawing/FillLinearGradientBrushTests.cs index 3d613adc05..047ffc9b7f 100644 --- a/tests/ImageSharp.Tests/Drawing/FillLinearGradientBrushTests.cs +++ b/tests/ImageSharp.Tests/Drawing/FillLinearGradientBrushTests.cs @@ -1,21 +1,17 @@ // Copyright (c) Six Labors and contributors. // Licensed under the Apache License, Version 2.0. -using System.Numerics; +using System; + +using SixLabors.ImageSharp.Processing; +using SixLabors.ImageSharp.Processing.Drawing.Brushes; + using SixLabors.ImageSharp.PixelFormats; using SixLabors.ImageSharp.Processing.Drawing; using Xunit; namespace SixLabors.ImageSharp.Tests.Drawing { - using System; - - using SixLabors.ImageSharp.Processing; - using SixLabors.ImageSharp.Processing.Drawing.Brushes; - using SixLabors.ImageSharp.Processing.Overlays; - - using Point = SixLabors.Primitives.Point; - public class FillLinearGradientBrushTests : FileTestBase { [Fact] @@ -26,8 +22,8 @@ namespace SixLabors.ImageSharp.Tests.Drawing { LinearGradientBrush unicolorLinearGradientBrush = new LinearGradientBrush( - new Point(0, 0), - new Point(500, 0), + new SixLabors.Primitives.Point(0, 0), + new SixLabors.Primitives.Point(500, 0), new Tuple(0, Rgba32.Red), new Tuple(1, Rgba32.Red)); @@ -39,7 +35,7 @@ namespace SixLabors.ImageSharp.Tests.Drawing Assert.Equal(Rgba32.Red, sourcePixels[0, 0]); Assert.Equal(Rgba32.Red, sourcePixels[9, 9]); Assert.Equal(Rgba32.Red, sourcePixels[199, 149]); - Assert.Equal(Rgba32.Red, sourcePixels[500, 500]); + Assert.Equal(Rgba32.Red, sourcePixels[499, 499]); } } } From 99ed4586adb589449a5487f7136cda7ca93f2cc3 Mon Sep 17 00:00:00 2001 From: Unknown Date: Fri, 20 Apr 2018 00:44:53 +0200 Subject: [PATCH 005/118] #542: use struct for ColorStops as proposed by @antonfirsov: improving readability and memory locality. --- .../Drawing/Brushes/LinearGradientBrush.cs | 59 ++++++++++++++----- .../Drawing/FillLinearGradientBrushTests.cs | 4 +- 2 files changed, 47 insertions(+), 16 deletions(-) diff --git a/src/ImageSharp.Drawing/Processing/Drawing/Brushes/LinearGradientBrush.cs b/src/ImageSharp.Drawing/Processing/Drawing/Brushes/LinearGradientBrush.cs index bfbeded698..99edb39f43 100644 --- a/src/ImageSharp.Drawing/Processing/Drawing/Brushes/LinearGradientBrush.cs +++ b/src/ImageSharp.Drawing/Processing/Drawing/Brushes/LinearGradientBrush.cs @@ -19,28 +19,59 @@ namespace SixLabors.ImageSharp.Processing.Drawing.Brushes public class LinearGradientBrush : IBrush where TPixel : struct, IPixel { + /// + /// A struct that defines a single color stop. + /// + public struct ColorStop + { + /// + /// Create a new ColorStop + /// + /// Where should it be? 0 is at the start, 1 at the end of the . + /// What color should be used at that point? + public ColorStop(float ratio, TPixel color) + { + this.Ratio = ratio; + this.Color = color; + } + + /// + /// The point along the defined gradient axis. + /// + public float Ratio { get; } + + /// + /// The color to be used. + /// + public TPixel Color { get; } + } + private readonly Point p1; private readonly Point p2; - private readonly Tuple[] keyColors; + private readonly ColorStop[] colorStops; /// /// Initializes a new instance of the class. /// /// Start point /// End point - /// a set of color keys and where they are.
