See reader questions & answers on this topic! - Help others by sharing your knowledge IRIX comes with several tools which convert images to or from SGI's RGB format. The executables are part of the eoe2.sw.imagetools subsystem, and include: fromalias - convert an Alias image to an IRIS image frombin - create an RGB IRIS image file from a binary dump of image data fromcmap - convert a color map into an image with one scanline fromcube - convert a Cubicomp/Vertigo image file to IRIS format fromdi - convert an old .di dithered image into an IRIS image fromface - convert a UNIX faceserver image into an IRIS image fromgif - convert a GIF image into an IRIS image frommac - convert a MacPaint image into an IRIS image frompic - convert a MOVIE BYU .PIC image to an IRIS image fromppm - convert an image in Jef Poskanzer's format into an IRIS image fromrla - convert a Wavefront image to an IRIS image fromsun - convert a sun image into an IRIS image fromtarga - convert a targa image into an IRIS image fromxbm - convert an X Bitmap image into an IRIS image fromxud - convert an xwd file into an IRIS image fromxwd - convert an xwd file into an IRIS image fromyuv - convert an Abekas yuv image into an IRIS image toalias - convert an IRIS image to an Alias image toascii - convert an IRIS image to text characters tobin - convert an IRIS image to binary dump of pixel data tobw - convert an IRIS image to black and white togif - convert an IRIS image to a Compuserve GIF image tomac - convert an IRIS image to MacPaint format tonews - convert an IRIS image into NeWS format topict - convert an IRIS image to Macintosh PICT format toppm - convert an IRIS image file into Jef Poskanzer's ppm image format tops - convert an IRIS image to PostScript toscitex - Convert IRIS images into Scitex CT2T images tosun - convert an IRIS image to a sun raster file totarga - convert an IRIS image to a type 2 targa image toyuv - convert an IRIS image to yuv format The source for each of these tools is in the 4Dgifts dev.dev_sw.giftsfull subsystem and installed in the directory /usr/people/4Dgifts/iristools/imgtools. Each also has a manpage. Similar tools for more formats ('fromeps', 'frompict', 'frompixar', 'fromps', 'fromtiff', 'fromutah', 'totiff', 'toutah', 'toxbm' and 'toxpm' at last count), as well as some which come with IRIX and a few miscellaneous cool image editing tools, are in ftp://ftp.sgi.com/graphics/bin/. 'fromjpeg' and 'tojpeg' can be found in ftp://ftp.clr.toronto.edu/pub/sgi/sgijpeg/. ftp://swedishchef.lerc.nasa.gov/ has 'fromvicar' in /image/conversion/from/, 'tocolps' and 'topcl' in /image/conversion/to/ and many other image-related tools in nearby directories. The Independent JPEG Group's free JPEG software (in ftp://ftp.uu.net/graphics/jpeg/) and ghostscript (in ftp://ftp.cs.wisc.edu/ghost/) don't speak RGB, but do convert many common formats to and from JPEG and PostScript respectively. Note that older versions ghostscript understand GIF images but newer ones do not due to copyright restrictions. Finally, 'imgworks' (in the imgtools.sw.tools subsystem) understands RGB, TIFF and FIT formats, and there are several freeware programs which work on SGIs and understand SGI's RGB format as well as many other formats: imtools ftp://ftp.sdsc.edu/pub/sdsc/graphics/imtools/sgi_4d/ xv ftp://ftp.cis.upenn.edu/pub/xv/ ImageMagick ftp://ftp.x.org/contrib/applications/ImageMagick/ netpbm ftp://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/ The Graphics File Formats FAQ (in ftp://rtfm.mit.edu/pub/usenet/news.answers/graphics/fileformats-faq/) lists many other graphics file viewing and conversion programs.
