Perhaps this is a bug in the ImageVision Library. If you load a grey scale Tiff into imgworks, and save it as an SGI file, one gets garbage out. imgworks seems to consider it is working with a colour dataset rather than monochrome, as various operations behave in a bizare manner. Infact loading and manipulating the grey scale image, after working with a colour tiff, causes imgworks to crash. A workaround is to restart before using the grey scale image, immediately use the function 'Colour to Greyscale' which seems to invert the image (?), then 'Invert' to return to normal. From then on its OK, and recognised as Grey Scale. Saveing as an SGI image then works correctly....
