These markers draw attention to specific areas in an image, guiding users through each step of a process. ==Outline color== Use a red outline (specifically hex color '''#f71701''') to delineate significant sections of your screenshots. This color choice ensures that the highlighted areas attract immediate attention. ==Corner style== Adopt square corners for the outlines to achieve visual harmony across your screenshot annotations. ==Line thickness== Balance the outline thickness between 4 and 8 points (pt) to achieve uniform visibility across screenshots of varying sizes. ==Align highlighted UI elements centrally== Align the UI element centrally within the red outline to enhance clarity and recognition. ;[[Image:Screenshot outline example|width=400]] ==Sequential step markers== Using sequential step markers on screenshots links each action within the UI to its corresponding text steps. This reduces ambiguity and the need for multiple images. It’s especially useful for longer instructions within the same window or context. By employing this method, you can show multiple instructions in a single screenshot with clear indicators for each action in the interface. Here’s an example of an appropriate scenario for using this approach: ;[[Image:Sequential Step Markers example|width=650]] To add these markers to your screenshots, open the screenshot in your preferred image editor. Then, save the markers from the [[Sequential step markers list]] and place them in the appropriate sections of the screenshot. =Image preparation and editing= ==Size== Ensure screenshots are compact in size. To enhance loading times and accessibility, particularly for users on slower internet connections, it's best to keep the dimensions of screenshots under 620 pixels in both height and width. ;[[Image:Example image size|width=620]] ==Cropping== *Ensure that larger screenshots are cropped to highlight the UI elements that pertain to the task at hand. ;[[Image:Cropped screenshot example|width=400]] ==Simplifications== *Simplify complex screenshots by eliminating non-essential UI elements, reducing cognitive load for users. Opt for muted grayscale tones like '''#D4D4D4''' and '''#E0E0E8''' instead of bright or dark colors. These lighter shades help to minimize distractions, allowing users to stay focused on the important parts of the screenshot. ;[[Image:Simplified screenshot example|width=820]] ==PII== *Eliminate all ''Personal Identifiable Information'' (PII) from screenshots, including emails, usernames, and any personal data that could potentially identify an individual. ;[[Image:Remove PII example|width=400]] ==Light mode== *Capture screenshots in “Light Mode” whenever possible, as “Dark Mode” images may not be as easily discernible for some users. [https://en.wikipedia.org/wiki/Paint_%28software%29 Paint] on Windows and [https://en.wikipedia.org/wiki/Preview_%28Mac_OS%29 Preview] on Mac are useful software for cropping and editing screenshot images. You can also use freeware such as [https://en.wikipedia.org/wiki/GIMP GIMP] on Windows, Mac and Linux. Other editing tools are listed at the end of this article.
