DigImage Raw Files

Contents Summary

The DigImage raw file format is the simplest possible file format. T he f irst two bytes give the height of the image (in pixels), and the third and fourth byte the width (again in pixels). The image is then stored with one byte per pixel in the next width*height pixels, ordered by row. The file may also contain some additional (optional) information after the end of the image (refer to the Development System documentation for SaveWindowFromBuffer(..)).

The command line for this variant of DigiFile is

C:..> DIGIFILE image_file /FR output_file [/O output_lut]
        [/W iw0 iw1 jw0 jw1] [/D [buffer]]

The output_file must be specified. The other command line switches have the following effect:

Switch	Effect
`/O output_lut`	Th is switch specifies the output look up table to be stored with the raw image file. If not specified, then the output look up table for the input image will be used.
`/W iw0 iw1 jw0 jw1`	Th is switch may be used to reduce the size of the source window to be converted to the raw output file. If not present, then the entire source image will be used. If the source image file itself were saved as a window, then the top left corner of the image is loaded to coordinates 0,0 (not the original position of the window) and so the new sub-window coordinates should be relative to this.
`/D [buffer]`	If the `/D` switch is included by itself, then the image, once loaded, will be displayed on the computer monitor. If `buffer` is also included, then the image will be displayed on the frame grabber monitor using the specified buffer number. Note that this last option is the only one for which DigiFile requires the frame grabber card to be installed.
