Photo Quality

Digital Collections' has a module called DCPHOTO that handles the moving and exporting of photo files in their system. You can customize the process using these switches in the dcphoto.pth file (see sample below table).

For instance, to change the output resolution you would use the -dpi switch in the dcphoto.pth file:

-ts 100 -lj 400 -t -ti -integrate -minfree 20 -ft TIFF8BIM -dpi 200 -xt .tif -he -domax 3 \

In this example, the export gallery has an attribute of 200 dpi on all photos. It will export the photos using Adobe PhotoShop's Macintosh File and Creator types, and it will add a .tif file extension to the image.

The Inspector

Digital Collections' client application has a palette called the inspector that allows you to name a photo, crop it, and size it before exporting it. There are some obscure fields in that palette and need a little explanation. This from GMTI:

The Quality field contains a default value which is multiplied times the Raster setting in use by the client in the effective dcshell.dcdl file. Usually the Raster setting is 100, and it is set in the /dot/project/digital/global/pref/dcshell.dcdl, which is the system default for this and other values.

The Quality value also is set in the global dcshell.dcdl file, but defaults to 1.8 when not set.

The value in the Quality field can be changed as needed to export higher (or lower) pixel densities as desired, but the value has to be less than or equal to the calculated number displayed in the Actual field after the image is cropped and sized.
