This is a request for an image conversion routine that I either missed or has yet to be posted. I would like to transport full- screen IRIS rgb files to the mac; using the Macpaint conversion routine is inadequate for images > 576x720 pixels in size. I have used "izoom" to shrink the images but the results were extremely disappointing. Does a conversion exist to convert IRIS "rgb" or "bw" images to one of the Macintosh color formats, eg, PixelPaint or Canvas? Thanks!!

I use the following method, which works o.k., but not perfect: 1. Convert the SGI image into a GIF image. (I use PBMPLUS or Utah Raster Toolkit to do this.) Available via anonymnous FTP from this host (Iris1.UCIS.Dal.Ca) in the /pub/ftp/sgi directory. 3. Transfer the file to your Mac. 4. Convert the GIf image into PICT II format using GIFFER. Available via anonymous FTP from Sumex-Aim.Stanford.Edu in the /info-mac/art/gif directory. 5. Use the image in your favorite software. The major drawback in this method is that the image gets converted into an 8 bit image. For most colour Macs this is not a problem, but if you need a 24 bit image this method is not sufficient. For 24 bit colour, it might be best to convert the image into a 24 bit colour TIFF image. (I do not know how to do this yet. Kevin Marinelli
