Hi all,

I'm trying to extract a subset of a PCI .pix image with gdal_translate 
but I keep getting the error "Option -prjwin incomplete, or not 
recognised.". What is wrong with my command syntax?

 >>   gdal_translate -prjwin 527609.250, 6699639.000 562350.500, 
6667716.500 -outsize 600 600  bigass.pix test.tif
    Option -prjwin incomplete, or not recognised.

    Usage: gdal_translate [--help-general]
        [-ot {Byte/Int16/UInt16/UInt32/Int32/Float32/Float64/

gdalinfo for the source image reports:

note that in this example I extracted the projwin coordinates from the 
gdalinfo center point and the lower right.

thanks in advance for your time.
