Typically an image file will be saved from within DigImage using [;KS Save buffer to file], [;KW Write window to file] or [;KC Save Windows .BMP bit map]. These three options all store the output look up table currently in use in addition to the intensity structure of the image concerned. Typically [;KS ...] should be used with the optional compression when saving entire buffers if the image is to be stored for a period of time. While uncompressed images may be read or written much faster than compressed images, they require much more space. If only a section of a buffer need be saved the [;KW ...] has the ability to save a window within a buffer. Windows are saved in an uncompressed form. Unless the window is relatively small, it may require more space than a compressed version of an entire buffer.
Images should normally be saved with [;KC Save Windows .BMP bit map] only when transferring an image to a Windows program.
A fourth method for saving a buffer as an image file is [;DP Dump the screen to PaintJet printer file]. This option saves the buffer in the same manner as [;KW Write window to file] but additionally prompts for and saves information about the size at which the image is to be rendered on a PaintJet (or LaserJet) printer, the image title and details of the rendering procedure (PaintJet only). While this final method is specifically intended for use with a PaintJet or LaserJet printer (as is emphasised by the default file extension .JET), images saved in this way may be treated in the same manner as any other type of image file supported by DigImage.
The format of the DigiFile command line depends on
the form of output required from DigiFile. We shall discuss first
output suitable for the colour PaintJet printers.
