The documents you scan and open in Readiris can be optimized in several ways with the Image and Layout Edting toolbar on the right side of the interface.
When a page has been scanned crookedly it can be deskewed - or straightened.
To deskew a page:
Select the page in the Pages panel:
Click the Deskew icon.
Readiris automatically detects if an image was made by a digital camera. Notice the camera icon on the page thumbnail.
Tip: if Readiris should not detect
that the image was made by a digital camera, Ctrl-click it and select
Digital Camera Image.
If the image was made from an angle, you can correct its perspective with the Deskew icon.
Notice that the Deskew icon looks different for digital camera images.
To deskew a digital camera image:
Select the image in the Pages panel.
Click the Deskew icon.
Automatic detection
Select the appropriate Content type.
Important: Readiris computes the image resolution based on the Content type you select. A correct resolution is required to obtain satisfactory OCR results.
Note: the fields Width and Height are only available when you select Other paper size.
Then click Apply to apply the automatic deskew.
If Readiris fails to detect the borders automatically, Readiris tries to find the best alternative Borders option.
Interactive definition
When Interactive definition is selected, you can drag the corners of the frame to a new position in order to align the frame with the page borders.
You can also move the horizontal borders vertically and the vertical borders horizontally.
Rectangular frame
When Rectangular frame is selected, you can move the horizontal borders vertically and the vertical borders horizontally.
No cropping
When No cropping is selected, no frame is displayed and no cropping can be done.
Note that the Borders options still work even if the borders of the document are outside of the image.
To rotate an image, click the Rotate icon. Then click the required option.
