Automatic despeckling
Sometimes documents contain a lot of "noise" - little black spots that occur when scanning low-
quality documents or using bad scanner settings.
To remove these little black spots, use the Despeckle slider. The more you move it to the right, the
larger the spots that will be removed.
Page Analysis Options
Note that you can also access these options via the Settings menu.
Page Analysis
Page Analysis is selected by default. This option divides your documents into recognition zones.
Without recognition zones, Readiris cannot process your documents. If you choose to disable this
function, you will need to draw recognition zones manually on your documents.
Page Orientation Detection
This option detects in which direction your documents are oriented and rotates them automatically.
Page Deskewing
This option staightens - or deskews - pages that were scanned at an angle.
Ignore Border Zones
When your scanner generates black borders around your documents, or when your documents
contain information that is partially cut from the page, Readiris tends to create recognition zones on
the borders of the document, even though they do not contain any useful content. In such cases it is
recommended to use the option Ignore Border Zones.
When you are done, close the Preferences window. The settings are saved automatically.
