Release Notes

4.4.0

  • added #205 ability to change rectangle color.

4.3.1

  • Fixed bug #201 - problem with comparing totally different pictures.

4.3.0

  • Include rectangles in ImageComparisonResult.
  • The resolved bug with 0.0 in differencePercent
  • improved and added missing tests.

4.2.1

  • Fixed bug #180 - problem with ImageComparisonUtil.readFromResources method.

4.2.0

  • added the ability to ignore some percent of differences for comparison.

4.1.0

  • added option to fill rectangles(167 issue)

4.0.0

  • refactored drawRectangles method due to SRP.
  • optimized isDifferentPixels to improve algorithm.
  • moved to Apache License 2.0
  • removed Point and used java.awt.Point instead
  • added Gradle.yml for GitHub actions
  • removed commandLine usage
  • renamed ComparisonResult to ImageComparisonResult
  • renamed ComparisonState to ImageComparisonState
  • added own RuntimeException for wrapping checked exception
  • added Gitter chat for communication.

3.3.1

  • Fixed bug #134: If image is different in a line in 1 px, ComparisonState is always MATCH
  • Fixed bug #136: deepCopy method throws IllegalArgumentException on shared BufferedImage
  • added GitHub workflow to the project.

3.3.0

  • Added option to get the pixels difference percentage between images in case of SIZE_MISMATCH.
  • Fixed NPE for default run from commandLine(#131)
  • Added configuration part to README.md.

3.2.0

  • Added ability to change pixel tolerance.
  • Improved algorithm to make it faster.
  • Improved JavaDocs.
  • Researched JPEG images, all work as expected.

3.1.1

  • Fixed bug #113: RED (not equals) and GREEN (ignored) areas are not shown at result image at the same time

3.1.0

  • Added the ability to draw excluded areas on the result image. Rectangles with the differences drawing RED color. Rectangles of the excluded areas - GREEN color.

  • Fixed root problem on the algorithm.

  • Added returning this for setters in ImageComparison and ComparisonResult.

  • renamed image1 => expected and image2 => actual.

  • Added writeResultTo() for ComparisonResult.

3.0.1

  • Fixed #98: Ignored area was not actually ignored.

3.0.0

  • Added ComparisonResult as a returning value for comparing. It contains:

    • expected(ex image1)

    • actual(ex image2)

    • ComparisonState, with conditions MATCH, MISMATCH, SIZE_MISMATCH

    • Result image, only if ComparisonState is MISMATCH. When it is MATCH or SIZE_MISMATCH no needs to create result image.

  • added minimalRectangleSize and maximalRectangleCount(sorted by rectangle size).

  • Added more tests to cover more test cases.

  • Refactored CommandLineUsage, moved main() method to separated class.

  • Added ExcludedAreas functionality, which helps to exclude some parts of the image.

2.2.0

  • Added ability to customize rectangle line width.

  • Moved the main method from Image Comparison to own class.

  • Made non-static threshold field.

  • Added Code of Conduct and Contributing pages.

  • Added Point model.

2.1.0

  • Added publishing to JCenter

2.0.2

  • fixed bug #11(finally!!)

  • fixed bug #43

2.0.1

  • fixed bug #21

2.0

  • use as a library

1.0

  • The program in Java that compares any 2 images and shows the differences visually by drawing rectangles.*

  • Implementation is using only standard core language and platform features, no 3rd party libraries and plagiarized code is permitted.

  • Pixels (with the same coordinates in two images) can be visually similar, but have different values of RGB. We are only consider 2 pixels to be "different" if the difference between them is more than 10%.

  • The output of the comparison is a copy of one of the images image with differences outlined with red rectangles as shown below.

  • No third party libraries and borrowed code are not using.
