Cardiris supports the following image formats: GIF, JPEG, JPEG
2000, MacPaint, Photoshop, PICT, PNG, QuickTime, TIFF
(uncompressed, packbits and Group 3 compressed), multipage TIFF
and Windows bitmap (BMP) images.
Note that you must always click the Export button to export the
cards.
Note that you can export contacts several times and in several
formats. Just change the output format and click the Export button
again.
Card Orientation Detection
By default Cardiris detects the card orientation automatically and
rotates the image when needed.
The Card Orientation option determines whether cards which
were scanned at a 90°, 180° or 270° angle, will be rotated left, right
or turned upside down automatically before the recognition begins.
Detecting the card orientation takes some time, however. Leave this
option disabled when you are sure no image rotation is required.
To disable automatic card orientation:
 Go to the Settings menu
 Uncheck the option Card Orientation Detection
Should you still need to rotate an image, use the manual rotation
button.
