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 |
