Annotation of 43BSDReno/contrib/isode-beta/others/quipu/photo/READ-ME, revision 1.1

1.1     ! root        1: PHOTOGRAPHS in the QUIPU directory service.
        !             2: 
        !             3: Use pr2pe to convert sunview pixrect files into `pe' files.
        !             4: 
        !             5: Currently there are 5 picture display processes defined:-
        !             6: Xphoto   - Display photo in X11 windoow environment
        !             7: sunphoto - Display photo in sunview environment
        !             8: ttyphoto - Display photo on a simple terminal
        !             9: hexphoto - Display photo in hex !!!
        !            10: t4014   - Display on Tetronix 4014 (emulating !) terminals.
        !            11: 
        !            12: Each can be tested with the file "sk"
        !            13: e.g. ttyphoto < sk
        !            14: 
        !            15: Display for other devices can be easily added.
        !            16: Take a copy of template.c, and supply the 5 routines defined.
        !            17: Look at sunview.c hexphoto.c ttyphoto.c t4014.c and winx.c examples.
        !            18: Then compile using:
        !            19: cc -o myphoto d_main.o decode.o build_trees.o interface.o myphoto.o
        !            20: 
        !            21: To get the QUIPU interfaces to call these routine when a photo is loaded, an
        !            22: entry of the form
        !            23: photo falco ttyphoto
        !            24: is needed in your dsaptailor file.
        !            25: This will tell the interfaces to use the program `typhoto' if your 
        !            26: terminal type (determined from the TERM environment variable) is `falco'.
        !            27: 
        !            28: ttyphoto's output can be modified with 4 environment variables:
        !            29: 
        !            30: photo_scale:   set to `small' (default), `medium' or `large'.
        !            31: photo_invert:  set true or false.
        !            32: photo_equal:    false - display photo as is.
        !            33:                true - apply histogram equalisation to try and improve quality.
        !            34:                edge -  Used `edges by expansion' to try to get a better photo
        !            35: photo_mapping:  This must contain a 16 charcter string.
        !            36:                The string is used to create the greyscale.
        !            37: Suggestions as to how to improve `ttyphoto' are welcome.
