Reference — KODAK Drivers for TWAIN-Compliant PC Applications 11-3
Image Archive Folders
Images saved to the PC hard disk by clicking COPY TO FOLDER or MOVE TO
FOLDER from within the driver supplied by Kodak should be read only with
that driver (see the “Important” paragraph below). One archive file on the
PC hard disk is created for each image and for each sound file copied or
moved to the computer hard disk. In addition to image data, an archive
file includes a thumbnail for its image, and all data from its “I
NFO” box.
Color and monochrome images in these archive files are composed of
uninterpolated data; they have not been “acquired” into your application.
This means they contain the 6 megabytes (MB) of data generated from the
array in the camera back and stored on the DCS 465 Camera Back
PCMCIA card. If you use the driver to interpolate a single image by
acquiring it into your TWAIN-compliant application, the size of the single
image file when saved will vary from application to application, but may
be 18 MB for a color image and 6 MB for a monochrome image.
IMPORTANT: Do not open image archive files (files that you create by copying/
moving images to the PC hard disk) with image software and then resave the data
with the same filename. The image files you copied/moved contain several
sections — one section with a TIFF version of the thumbnail, and then another
section with the image data. When you open the file, only the TIFF thumbnail is
opened, and if saved, only the thumbnail is saved — not the image data. For this
reason, you should only open these files from within the driver image window
using the C
HANGE FOLDER button as described later in this chapter; this will ensure
that you obtain the image data as well as the thumbnail.
