getqcr - Photograph an RLE image with the Matrix QCR-Z camera
getqcr
[ -v ] [ -c ] [ -d ] [ -f ] [ -p xpos ypos ] [ -e exposures ] infile
Getqcr
photographs an image on the Matrix QCR-Z camera. The program reads the image
once for each channel, and displays this on QCR-Z, moving the filter wheel
as appropriate. The colormap is currently ignored, so one must be applied
first if needed (see applymap(1)
). Since the QCR supports large images (2K
or 4K pixels in size), most images will need to be stretched to fill the
QCR-Z's image area. Both fant(1)
and rlezoom(1)
perform this function.
The
current support library assumes the QCR-Z is connected to an HP Series 300
machine, the library may need modifications for other HPIB interfaces.
- -v
- This enables verbose output. Since exposing large images takes several
minutes, this is generally useful to monitor progress.
- -e exposures
- Expose
the film exposures number of times. This is much faster than running getqcr
multiple times.
- -d
- Double expose (same as "-e 2").
- -f
- Select high resolution
(4K)
mode. Default is low resolution (2K)
.
- -c
- Center the image. This ignores
the position values in RLE header, and centers the image in the middle
of the QCR-Z's camera field. The proper resolution (2K or 4K) is automatically
selected depending on the image size (-f is ignored if -c is specified).
- -p
xpos ypos
- Position the image at a specific point. Note getqcr uses the
RLE coordinate system (origin at the bottom left) instead of the QCR-Z coordinate
system.

The color map should be applied automatically.
Currently uses "row" mode, it may run faster in "raw" mode.
Single channel
images should be photographed in black and white (they currently come
out red).
It was written for the 4x5 film back. Shutter and film advance
controls for the 35mm and Oxberry backs are not implemented.
