           Picasso 3.8

  Picasso is an interactive drawing tool in the style of idraw. It is
based on John Ousterhout's tk package and on its canvas widget, and
also requires tclX and tkX extensions (see below).

** Original features provided by picasso include:

- Greyscale image and Postscript object management.
    Currently supported formats are: Postscript, PPM, GIF, Pict,
                                     X Bitmap, XPM, X Window, X Region
    Picasso implements interactive image rescaling, rotation, and
      color control.

- Latex object management
    Interactive latex object creation. Two representation are
      provided: uncompiled objects can be included as latex source in a
      latex picture, while compiled objects can be rescaled and
      rotated. The bounding box of uncompiled objects is displayed
      under picasso, while compiled objects appear exactly as they
      will is the final document.

- Latex picture generation
    Picasso can generate a latex picture mixing postscript drawing and
      latex objects. The picture is resizable at include time using
      the \epsfsize facility.

- Postscript generation for subparts of the drawing: allows creation
  of big objects hidden by white objects, and selective choice of the
  interesting region for Postscript generation.

- High customization possibilities due to the use of Tcl for
    initialization and drawing files.

** Features still to be implemented include

- Support for text and oval rotations
- Global zooming ability
- Undo mechanism

** Required packages
  tcl7.1 and tk3.4 or later.
  tclX7.1a or later.
  Image format management is entirely based on the PbmPlus package.
  The ppm libraries are needed to compile picasso, and the following
    executables must be accessible from your PATH environment
    variable: giftoppm, xpmtoppm, picttoppm, pnmfile, xwdtopnm.

** How to install
  There is no configuration tool for picasso: you will have to edit
the makefile and set variables to appropriate values.

  Type "make" to compile.
  You can try the program before installing by typing:
    "PicassoLib=$PWD ./picasso"
  If everything's ok, you can install by typing "make install".

  The program is known to compile on the following platforms:
	- Sun SS10 running sun4OS4.1.3
	- Sun SPARC ELC running sun4OS4.1.1
	- DECstation 5000/200,  100 dpi display
	- Silicon Graphics 4D/310
        - Indigo machines.
