2633  
2634   Added i/o for spectral pictures to rmtxop, the first program that can
2635   ingest them.  (Only rtrace, rcontrib, and rfluxmtx can render them.)
2636 + New symbolic rmtxop -c options, such as RGB, XYZ, S (for scotopic)
2637 + and M (for melanopic) make color conversions simpler.  Alternatively,
2638 + a reference matrix or picture may be given and the color space of
2639 + that file will be used.  The -C option takes either a symbolic
2640 + color space or reference file and is "sticky," so it applies to
2641 + all subsequent input files that do not have their own -c right ahead
2642 + of them.
2643 +
2644 + Added spectral picture support to rcrop and radcompare.
2645 +
2646 + Added new utility, rcomb, which is something like a combination
2647 + of rmtxop and pcomb, it works with all the inputs and
2648 + outputs that rmtxop handles, but allows for general expressions
2649 + like those in pcomb for putting matrices together, working on
2650 + an element at a time.  (No resizing of matrices or accessing
2651 + neighboring elements, as permitted in pcomb.)  It saves memory
2652 + over rmtxop by operating on a row at a time, so can handle
2653 + input and output matrices with any number of rows.  It does
2654 + provide for a single matrix-multiplication operation at the end,
2655 + which only requires memory for that final matrix.
2656 +
2657 + Added support for filtering hyperspectral images to pfilt.
2658 +
2659 + Added support for 1- and 3-component float matrix i/o to
2660 + pcomb to allow for better interoperability.
2661 +
2662 + Added support for -co+ option to rtpict, so it can directly
2663 + produce hyperspectral images.
2664 +
2665 + Added new "specdata" and "specpict" primitives to support
2666 + interpolated spectral data files and hyperspectral images
2667 + as patterns.
2668 +
2669 + Added support for multispectal sampling in rsensor, which will
2670 + put out as many color channels as specified in any -cs option
2671 + (default is 3 for RGB).
2672 +
2673 + Added ability of mgf2rad to convert spectral data at least
2674 + for light, glow, plastic, and metal primitive types.  Need
2675 + to use new '-s' option to get new output.
2676 +
2677 + Added handling of spectral images to rcode2bmp script.
