NAME

mkImg - make an image with specified size, pixel type and value

SYNTAX

mkImg [-xsize <xsize>] [-ysize <ysize>] \
       [-xstart <xstart>] [-ystart <ystart>] \
       [-nbands <nbands>] [-title <title>] \
       [-pt <pt>] [-pv <pv>] [-impv <impv>] <outimage>

DESCRIPTION

mkImgcreates an image of any size, pixel type andvalue, specified by the switches. <outimage> is thename of the new image.

   Switches:           Meaning:        Default value:
-----------------------------------------------------
-xsize <xsize>     Horizontal size        512
-ysize <ysize>     Vertical size          512
-xstart <xstart>   xstart                 1
-ystart <ystart>   ystart                 1
-nbands <nbands>   number of bands        1
-title <title>     image title            "new image"
-pt <pt>           pixel type             unsigned byte
-pv <pv>           pixel value            0
-impv <impv>       imaginary pixel value  0

If the title contains more than one word, surround itwith "double quotes". The pixel type may be given aspixel number or short name, according to the following table:

   Pixel number:    Short name:    Pixel type:
-------------------------------------------------
        3               ub         unsigned byte
        4               sb         signed byte
        5               us         unsigned short
        6               ss         signed short
        7                i         integer
        8           r or f         real (float)
        9                c         complex
       10                d         double
       11               dc         double complex

The -impv switch is only meaningful in case of complexand double complex pixels, where the "-pv" switch isused to specify real part, and "-impv" the imaginarypart.
