Developing workflow solutions 48 Feature Document color Resolution Image processing capabilities Details Supported for input: • Bitonal • Grayscale • Color Supported for output: • Bitonal • Color Input is accepted from documents scanned at 150 dpi-600 dpi. Performance is best with documents scanned at 300 dpi. The following image processing tasks are available: • Despeckle • Deskew • Rotation (90‑degree increments) • Identification of text without output of text Accuracy factors The accuracy of the OCR module depends on the quality of the image scanned from the document, which is determined by the following factors: • Media type-More‑reflective specialty media may result in poor‑quality scanned images. • Document condition-Aged, wrinkled, or creased documents may result in poor‑quality scanned images. • Document image quality-Low resolution or color depth of the scanned image or poor print quality in the scanned document may result in poor‑quality scanned images. • Document alignment-Skewed or slightly rotated documents, such as pages fed through a misaligned automatic document feeder (ADF) may cause difficulty in reading the scanned image. Using the included solution database The LDD system includes a Firebird database that your solutions can use to store information instead of a custom database. This allows you to create and modify tables without first creating a custom database, and data in the included database is automatically migrated to a new version when the Firebird database installation used by LDD is upgraded. The included database is SOLUTIONINFO.fdb, located in the \firebird\data\ folder where the LDD database is installed, along with the system databases. The credentials for the database are as follows: • User name-framework • Password-rivet
