+# image-diff
+[![Go Report Card](https://goreportcard.com/badge/github.com/olegfedoseev/image-diff)](https://goreportcard.com/report/github.com/olegfedoseev/image-diff)
+
+Allow you to calculate the difference between two images. Primarily for documents for now.
+
+
+You give it first image, like that:
+
+![test-only-text](testdata/test-only-text.png?raw=true "test-only-text")
+
+And second one:
+
+![test-text-number](testdata/test-text-number.png?raw=true "test-text-number")
+
+And you get diff percent (6.25%) and visual diff:
+
+![diff](testdata/diff.png?raw=true "diff")
+
+# How to get and use
+
+```
+go get -u github.com/olegfedoseev/image-diff
+```
+
+And in you code:
+
+```
+import "github.com/olegfedoseev/image-diff"
+
+diff, percent, err := diff.CompareFiles("test-only-text.png", "test-text-number.png")
+if percent > 0.0 {
+    fmt.Printf("images is different!")
+}
+```
