The images and/or text associated with a document can be highlighted, allowing you to place special emphasis on a particular portion of an image or a particular line of text. This annotation type can be linked between the image and text of a document.
Highlighting an image
When in Highlight mode, a portion of an image can be highlighted using the mouse. The selected region will be highlighted in the default color.
Note: By default, adding a text highlight automatically creates an image highlight linked with that text highlight. Learn more.
