-------- ChartFolio for Zinc: DISCLAIM.TXT --------------------------
-------- Disclaimer for Beta Release of Product ---------------------
=====================================================================

DPC Technology is developing the "ChartFolio for Zinc" product line
concurrently with the alpha, beta, and release-candidate versions of
Zinc Software's ZAF v5.1 product line.  A result of this development
timeline is that many of DPC's ChartFolio for Zinc products are only
now in their alpha stages of development following Zinc's recent beta
releases.  Other ChartFolio products are now in late beta following
the successful release-candidate version of Zinc ZAF v5.1.

This file identifies components or functionality of the ChartFolio
for Zinc/ZAF (v5.1) product lines that are in various stages of
alpha and/or beta-testing and are either: (1) not planned for
implementation, (2) not yet implemented, (3) not yet complete,
or (4) not yet tested.

Developers should review this listing to make informed decisions
before including these objects in their code.  Unless otherwise
noted, DPC's intent is to complete *MOST* disclaimed components
and functionality in the near future.                          


  ChartFolio for Zinc/ZAF Release Candidate Product-- 05-Jun-1997
  ===============================================================

    1.0     Non-verified Compilers:
    2.0     Products still under (Alpha and/or Beta) Development:
    3.0     Incomplete "ChartFolio for Zinc" Product Features:
    4.0     Known "ChartFolio for Zinc" Bugs
    5.0     Win-32 DLLs not yet supported



1.  Non-Verified Compilers:
---------------------------

    The current beta-version of ChartFolio for Zinc/ZAF was developed
    using Borland C++ 5.02 on a standard PC running Microsoft Win-95.

    1.1 Motif/UNIX:

        ChartFolio has been tested on: Linux, Solaris, Dec Unix, AIX.
        ChartFolio has NOT yet been tested on: SCO, SGI, HP/UX.

    1.2 MS-Windows:

        ChartFolio has been built (using Zinc's ZMAKE.EXE) and tested
        on: Win-3.1, Win-95 and Win-NT.

    1.3 DOS:

        This product MAY not be supported. Support will depend on the
        abilities of ZAF for DOS to support a pixel-oriented display/
        device-context.  ChartFolio compatibility with ZAF for DOS
        will be determined following Zinc's release of ZAF for DOS.

    1.4 Macintosh:

        Verification will follow Zinc's release of ZAF for Macintosh.

    1.5 OS/2:

        Verification will follow Zinc's release of ZAF for OS/2.

    1.6 Curses:

        Not supported.  Curses environments will not support
        ChartFolio's requirements for a pixel-oriented GUI
        display/device-context.

    1.7 NEXTSTEP:

        Not supported.  Zinc has discontinued this product line.


2.  Products still under (Alpha and/or Beta) Development:
---------------------------------------------------------

    A set of add-on products which implements fully generalized
    cross-platform charting functionality for the Zinc ZAF v5.1
    product line will be available from either Zinc Software
    or DPC Technology:

    2.1 Standard 2D/3D API (Application Programmer Interface):

        This product is now in production.  The Standard 2D/3D API 
        is the generalized two-dimensional and three dimensional 
        implementation of the standard ChartFolio API.
        It delivers a full set of 2D/3D chart types, and extends
        the data-indexing methods of the ChartFolio chart-model to
        allow users to specify arbitrary data-index values.

    2.2 ChartFolio ARI (Advanced Real-Time Interface):

        This product is in an alpha-development/test stage.  The ARI
        product provides an explicit implementation and extension of
        the base 2D/3D API framework to facilitate real-time charting.

    2.3 ChartFolio AUI (Advanced User Interface):

        This product is in a prototype development stage.  The AUI
        extends chart-attribute-control to application end-users by
        implementing a set of chart-dialog-objects and associated
        chart-control-objects that give end-users complete control
        over all aspects of chart appearance such as: 2D/3D modes,
        view-angles, color(s), etc.  These chart-dialog and chart-
        control objects interface directly with the ChartFolio
        2D/3D standard programmer API.


3.  Incomplete "ChartFolio for Zinc" Product Features:
------------------------------------------------------

    The ChartFolio/Zinc ZafChart product can already be used to
    implement reliable charting in Zinc/ZAF applications.  However,
    some charting features, such as various sets of display-dependent
    features are still under development between Zinc Software and
    DPC Technology.  Some of these features are:

    3.1 ZAF Display-Font Support:

        The mapping of ChartFolio Auto-Scale-Font-Spec objects into
        the underlying framework of Zinc/ZAF display-font support
        mechanisms has not yet been defined.

        This means that the font auto-scaling and font rotation of
        other ChartFolio implementations is not yet functional for
        the ChartFolio for Zinc product line.

    3.2 ZAF Display-Bitmap Support:

        This functionality is currently not implemented, and has no
        current default or work-around.

    3.3 ZAF Persistence:

        A ZafChart object can be persisted, but the persistence of
        the data-state of the encapsulated chart-model, chart-engine,
        and chart-engine objects has not yet been implemented.

    3.4 Print Functionality for ZafCharts:

        Depends on the print support delivered by the underlying ZAF
        framework, and is currently not implemented.  This 
        functionality is planned for delivery subsequent to Zinc's 
        implementation of printing under ZAF 5.1.

    3.5 Internationalization:

        Is not supported for this version of ChartFolio.  This
        capability will be implemented in a future version of
        ChartFolio for Zinc.

4.  Known "ChartFolio for Zinc" Bugs:
------------------------------------------------------

    4.1 3D Pie Chart Drawing

        3D Pie charts have a slight rendering problem (somewhat noticeable
        under Windows, somewhat more so under Motif) where a wedge (as 
        viewed from the side of a pie chart) doesn't precisely align with
        the slice (as viewed from above).  A fix is planned for a future
        version of ChartFolio for Zinc.

    4.2 Tick Mark Staggering

        The labels associated with staggered tick marks do not position 
        themselves quite right (the labels are drawn on top of the ticks, 
        rather than below).  A fix is planned for a future version of 
        Chartfolio.

5.  Win-32 DLLs not yet supported:
------------------------------------------------------

        ChartFolio DLLs for Zinc on Win-32 are not yet tested.
