Handles the acquisition from scanners (devices) that are TWAIN compliant.
Selecting the desired scanner and acquiring an image is as easy as thinking
of it :-) No more troubles with DIBs conversion, and misterious message
handling! Direct source selection from an easy to pick available sources
list.
Tested with HP, Epson, Logitech, Mustek and several other scanners
over a wide range of computers. Works with Delphi 1, Delphi 2, Delphi 3,
Delphi 4, CBuilder 1.0 and C++Builder 3.

user selected a source) |
|
|
- |
corrected the help file for DeviceOnLine (use of TEtwBoolean
instead of boolean) |
|
|
- |
corrected the help file for BitDepth (now shows bit depths up
to 15 bpp) |
| 2.02 |
27 feb 1997 |
- |
extended the property BitDepth to hold
bit depths up to 15bpp (bits per plane), thus
being ready to acquire images up to 45 bits |

- |
added full support for Delphi 1 (16
bit) |

linked, switched on and operative |
|
|
- |
added property BitDepth to set the number of bits
per sample |
|
