You can set a default Auto Crop mode by changing the value of the DefaultAutoCropMode setting in the <appSettings> section of your Web.config file. This setting can be set to On or Off. When set to On, the Auto Crop mode is turned on and white space around an image is removed when scanning. When set to Off, the Auto Crop mode is turned off and white space is not removed.
The selected value is reflected in the More Options dialog within the software.
The default value of the DefaultAutoCropMode setting is Off.
