Annotation of 43BSDReno/contrib/isode-beta/others/quipu/photo/READ-ME, revision 1.1.1.1

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.
