Changing the Zoom Factor

Introduction

The context menu includes several image zoom options. The default zoom factor is Zoom to Fit.

The Zoom Input dialog box enables you to enter a zoom factor or select a zoom factor from among the default choices provided. Buttons in the Zoom Input dialog work the same way as their counterparts in the context menu do.

Zoom factor choices are applied to the selected image as you make them. You can cycle through zoom factor options to see what effect they have on the image.

If the browser zoom factor is not 100%, True Size is not available and images might be blurred. Ensure that your browser and your operating system (OS) zoom factors are both set to 100%. See Ensuring the Browser and OS Zoom Factors are 100 Percent .
