Annotating Images with SnagIT

Why

SnagIt has built-in annotation features that are easy to use and can help you to enhance your screen captures or other images. Annotations can be used to emphasize important information for increasing learner understanding.

From Capture to Final Image

Annotating an image usually begins with the original screencapture, graphic or photo image. A series of edits, if needed such as cropping are made, and then the annotations are added. The following example illustrates the process from screencapture to final image, and the thought process used. Refer to Basic Editing of Images with SnagIt for instructions on cropping an image and the other editing tools that will be used in this example.

Capturing

If you need to capture an image from your computer, refer to the how-to page on Capturing Images with SnagIt. This example starts with a table in Microsoft Excel that has been captured as a window.

Cropping

In this example, there is more information in the table than will be discussed, and the final graphic will be incorporated into a PowerPoint presentation. The table is cropped to remove the Excel window border, and the extra information.


Edge Effects

The top portion of the table is the most important, but the speaker wants to make it clear that the original table contains more information, so the sharktooth edge effect is used to show that the document has been "snipped" from the original.


Highlight

The slide that the final graphic will be inserted into is about the decline in the use of backcountry campgrounds, so the data is highlighted using the highlight tool.


Arrows

The decline began in 2002, so an arrow is added to show the beginning of the decline.


Text Box

A text box is added to provide a caption for the arrow.


Graphic Annotations Complete

The graphic is now complete, and can be saved as a .gif or .jpg image to be inserted into PowerPoint.

Tip

If you save a copy of your SnagIT file as a .snag file, you can go back and edit your SnagIT annotations. After saving the .snag file, you can then save it again to a graphic format such as .gif or .jpg that can be used to bring your image files into other programs.
