The special device name must be a generic SCSI device or a +symlink to such a device. Under Linux, such a device name could be +.I /dev/sga +or +.IR /dev/sge , +for example. +.SH IMAGING MODES +The Polaroid DMC supports a number of imaging modes. This driver supports +five of the imaging modes: +.PP +.TP +.B Full Frame +This mode corresponds to the 801-by-600 pixel full-color full-frame image. +.TP +.B Viewfinder +This mode corresponds to the 270-by-201 pixel grey-scale viewfinder image. +This image is acquired very quickly. +.TP +.B Raw +This mode corresponds to the 1599-by-600 pixel "raw" image from the +CCD. It is grey-scale, with pixels alternating horizontally between +red, green and blue stripes. The pixels are twice as high as they are +wide, so the image is distorted. +.TP +.B Thumbnail +This mode corresponds to the 80-by-60 pixel full-color thumbnail image. +.TP +.B Super Resolution +This image is a 1599-by-1200 pixel full-color image constructed by filtering +and interpolating the "raw" image. The filtering and interpolation is +done in software, so this mode is very slow. Also, this mode places +restrictions on how the image is read which means that the "preview" mode +of xscanimage does not work in Super Resolution mode. +.RB ( xcam (1) +and the non-preview modes of +.BR scanimage (1) +and +.BR xscanimage (1) +work fine, however.) +.PP +.SH OTHER SETTINGS +.TP +.B ASA Setting +This setting adjusts the camera's sensitivity. You can choose one of +25, 50, or 100 "equivalent" ASA. +.TP +.B Shutter Speed +You can select a shutter speed from 8 to 1000 milliseconds. The shutter +speed is quantized in units of 32 microseconds. +.TP +.B White Balance +You can choose one of "Daylight", "Incandescent" or "Fluorescent" +white balances. This setting more-or-less corresponds to the +"Color Temperature" settings on Polaroid's Windows and Mac software. +.SH CONFIGURATION +The contents of the +.I dmc.conf +file is a list of device names that correspond to DMC +scanners. Empty lines and lines starting with a hash mark (#) are +ignored. A sample configuration file is shown below: +.PP +.RS +/dev/scanner +.br +# this is a comment +.br +/dev/sge +.RE +.SH FILES +.TP +.I /etc/sane.d/dmc.conf +The backend configuration file (see also description of +.B SANE_CONFIG_DIR +below). +.TP +.I /usr/lib64/sane/libsane\-dmc.a +The static library implementing this backend. +.TP +.I /usr/lib64/sane/libsane\-dmc.so +The shared library implementing this backend (present on systems that +support dynamic loading). +.SH ENVIRONMENT +.TP +.B SANE_CONFIG_DIR +This environment variable specifies the list of directories that may +contain the configuration file. On *NIX systems, the directories are +separated by a colon (`:'), under OS/2, they are separated by a +semi-colon (`;'). If this variable is not set, the configuration file +is searched in two default directories: first, the current working +directory (".") and then in +.IR /etc/sane.d . +If the value of the environment variable ends with the directory separator +character, then the default directories are searched after the explicitly +specified directories. For example, setting +.B SANE_CONFIG_DIR +to "/tmp/config:" would result in directories +.IR "tmp/config", +.IR ".", +and +.I "/etc/sane.d" +being searched (in this order). +.TP +.B SANE_DEBUG_DMC +If the library was compiled with debug support enabled, this +environment variable controls the debug level for this backend. E.g., +a value of 128 requests all debug output to be printed. Smaller +levels reduce verbosity. +.SH BUGS +In the "Full Frame" and "Raw" modes, images must be read in units +of entire lines. The driver performs no buffering in these modes; +if you ask sane_read to read a non-integral number of lines, it +may read less than you ask for. If you ask sane_read to read +less than a single line, it returns SANE_STATUS_INVAL. +.PP +In the "Super Resolution" mode, images must be read in units of +\fItwo\fR lines (3198 pixels or 9594 bytes). If you try to read less +than two lines, you get SANE_STATUS_INVAL. The Super Resolution mode +is very slow. +.PP +In the "Viewfinder" and "Thumbnail" modes, the entire image must +be read in one SCSI transfer. In this case, the driver performs +buffering and you can read the image in as small an increment as you +like. + +.SH "SEE ALSO" +.BR sane (7), +.BR sane\-scsi (5) + +.SH AUTHOR +David F.
