Benefit |
| Driver Interface |
Consistent from scanner to scanner |
Varies from scanner to scanner |
ISIS users need not learn interface of every scanner |
| Scanner Features |
Fully supports every feature of every scanner |
Not all TWAIN drivers fully support every feature of every scanner |
With ISIS, every scanner feature is supported no matter what scanner is being used |
| Speed |
Always scans at rated speed of scanner |
Doesn't always scan at rated speed |
ISIS allows you to take full advantage of the power built in to your scanner |
| Application Interaction |
ISIS applications interact with all ISIS scanners in a consistent way, and vice versa. |
Interaction is not consistent across all scanners; a new scanner may interact differently with an application |
ISIS is readily compatible; less testing is required, which lowers development costs |
| Display Images |
|
|
TWAIN only does scanning whereas ISIS supports image display; if you scan with TWAIN and you need image display, you must write it yourself or license it from someone else |
| Rotate Images |
|
|
ISIS allows an application to scan in landscape orientation and rotate in real-time to portrait to increase pages per minute |
| Consistently Write to Popular File Formats (JPEG, TIF, PCX, BMP, etc.) |
|
|
ISIS conforms to your needs and existing file formats; TWAIN drivers depend on the individual drivers |
| Scanner Interaction |
ISIS driver intelligently queries scanner as to capabilities, relays only appropriate choices to application GUI |
TWAIN driver often does not interact with application GUI |
Simplifies scanner setup; allows control of scanner from within application |
Compress to JPEG 2000 and Other Formats |
|
|
Images scanned using ISIS may be easily compressed, saving valuable storage space and speeding transfer times |
| Read Image Files from Disk, Website or Database |
|
|
ISIS enables you to create a centralized input management solution that can collect information in varied formats and from varied mediums |
| Read and Write Multipage Image Files |
|
|
More often than not, scanned documents are not standalone and contain more than one image on more than one page; ISIS allows you to streamline the processing of this input by not forcing you to treat every page as a separate document |
