In February, 2002, I purchased a CanoScan FS4000US, a nice
high-dpi film scanner. Unfortunately, the driver provided with
it does not support batch scanning to files. My choices were to
write a TWAIN client that wrote each image to disk, or purchase
GOBS of memory. I chose the former because it improved the
workflow for me.
TwainTiffBatcher accepts a number of input items and then
repeatedly scans images to TIFF files by retrieving them from a
TWAIN device. This allows for easier batch scanning workflows
without the memory requirements of keeping all the images loaded
Possibly later I will have more time, but right now, I can only
give a brief description of the program and its use. The inputs
to the file writing engine are:
- TIFF Output Directory
- The directory into which tiff files are written.
- Filename printf string
- A printf string used to derive filenames. This string will
be used to format one decimal argument, so it should have a %d in
it somewhere for the index number to be placed. I use:
scan-%03d.tifwhich formats numbers to a minimum of
three digits (i.e., file with index 5 would be
- Beginning index
- The first index number to use when generating a filename.
Each time an image is written, the index is increased by one for
the next image's filename generation.
- Update beginning index
- Updates the text field for beginning index when the scanner
driver interface window is closed. This allows you not to worry
about keeping track of the files to know what index should be
- Save settings
- Saves settings permanently in the registry for the next time
the program is executed
- Remove Stored Settings
- Removes the settings stored in the registry.
TwainTiffBatcher will always check to verify whether writing an
image would overwrite an existing file. In the case it does, it
warns you and asks for permission to overwrite the file.
Additionally, it tries to predict a write-failure for lack of
security or write permissions type situations. It cannot predict
failure due to lack of free disk space, but will handle that
situation gracefully when it arises.
