This mode is based on comparing image color histograms. Therefore, for the example of 10% different pixels, a threshold of 11% would consider both images to be equal: The algorithm has a threshold parameter that defines the criterion by which images are considered to be equal. For example, a difference of 10% means that 10% of the pixels are different. It presents the images differences in percentage. This mode compares the color of corresponding pixels of two images with the same dimensions.

Note that pixel differences can occur which are not noticeable by the human eye due to various factors (graphics card drivers and hardware, operating system, anti-aliasing, etc.) which makes the Strict mode unsuitable at times. The "Strict" mode is a pixel by pixel comparison which offers no configuration options:

Here you can choose the desired mode, configure it and save the changes to the verification point. Then click on the button "Edit Verification Point" to see the configuration tool and click on the tab "Comparison Mode". To edit the comparison mode open the screenshot verification point in the Squish IDE: (The default comparison mode is "Strict".) Editing the comparison mode ¶ The comparison mode of a screenshot verification point can only be modified after it has been created. Squish supports different comparison modes for screenshot verification points ("Strict", "Pixel", "Histogram").

The following things are suspected to contribute to the problem:Ĭolor management of the graphics card driver Unfortunately we do not know the cause of these differences. Typically these differences are just a few pixels, and the individual pixel values typically only differ by a very small amount. These differences tend to be so small that when comparing screenshots the human eye cannot see them or modern monitors are not able to display the differences. In addition to these above reasons for screenshot differences, there seem to be other reasons for such differences. Unknown reasons for screenshot differences ¶
The application may be displaying constantly changing things, like the date or time. The application or the respective object may have changed appearance in general.
Taking screenshots of the same object or window can result in larger or minor pixel differences between the screenshots taken at different times. Obvious reasons for screenshot differences ¶ (see below), which means that they are generally more brittle and error-prone than property verification points. The reason for this is that screenshot/image verifications are subject to pixel differences, object geometry differences, etc. Screenshot/image verifications should only ever be used when it is not possible to verify the desired value, text, number, etc. This article contains information about screenshot (image) verification points.

The original image is used to give the correct dimentions to its container. We used a figure element to wrap our original image, the modified image and the slider handle: 👋 A new version of this component is available.

If you look at the Sony Ultra HD TV product page, they use this approach to emphasize the difference between their display resolution and a standard one. A comparison image slider is one of those.
When you create a product page, there are some effective UX solutions that can be used to make the user 'feel' the product.
