SkiaSharpCompare

Compares images

.NET build and test Nuget Donate

Inspired by the image compare feature "Visual verification API" of TestApi this code supports comparing images by using a tolerance mask image. That tolerance mask image is a valid image by itself and can be manipulated.

SkiaSharpCompare focus on os agnostic support and therefore depends on SkiaSharp.

NOTE: The Alpha-channel is ignored.

Example simple show cases

bool imagesAreEqual = SkiaSharpCompare.ImagesAreEqual("actual.png", "expected.png");

// calcs MeanError, AbsoluteError, PixelErrorCount and PixelErrorPercentage
ICompareResult calcDiff = SkiaSharpCompare.CalcDiff("actual.png", "expected.png");

Example show case allowing some tolerated diff

Imagine two images you want to compare, and want to accept the found difference as at state of allowed difference.

Reference Image

actual image

Actual Image

actual image

Tolerance mask image

using "compare.CalcDiff" you can calc a diff mask from actual and reference image

Example - Create difference image

using (var fileStreamDifferenceMask = File.Create("differenceMask.png"))
using (var maskImage = SkiaSharpCompare.CalcDiffMaskImage(pathPic1, pathPic2))
var encodedData = maskImage.Encode(SKEncodedImageFormat.Png, 100);
encodedData.SaveTo(fileStreamDifferenceMask);

differenceMask.png

Example - Compare two images using the created difference image. Add white pixels to differenceMask.png where you want to allow difference.

var maskedDiff = SkiaSharpCompare.CalcDiff(pathPic1, pathPic2, "differenceMask.png");
Assert.That(maskedDiff.AbsoluteError, Is.EqualTo(0));
