WPG.svobject
© 1994 by Andreas R. Kleinert.
FREEWARE. All rights reserved.
Version : 2.4
Release Date : 22.05.1994
Requirements
~~~~~~~~~~~~
- OS V2.04+ (V37)+ and its libraries
- superviewsupport.library V1+
Description
~~~~~~~~~~~
WPG.svobject is an external Library-Module for the superview.library V2+.
It contains SVDriver-Support for the superview.library V3+, and
needs any SVDriver with Bitplane-Support.
It supports reading of WPG (WordPerfect) BitMap Files.
In detail these are :
Reading :
- WPG BitMap (GreyScaled) with 1, 2, 4 or 8 Bits ColorDepth
- WPG BitMap (ColorMap) with 1, 2, 4 or 8 Bits ColorDepth
Writing :
(not supported yet)
Remarks
~~~~~~~
WordPerfect WPG Files do not necessarily have to contain BitMap-Graphics,
they also may contain various other data, e.g. Vector-Graphics.
If a WPG File contains a BitMap-Graphic in any of its Chunks, this will
be displayed, otherwise the file will be rejected.
If a file does not contain any color information, WPG.svobject will
generate GreyScales by default.
This will be mentioned in the FileInfoRequester.
This version actually has been tested with graphics with 1, 4 and 8 Bit
ColorDepth (2, 16 and 256 Colors).
Due to the fact, that the 2 Bit-Routine is identically to the 1 Bit-
Routine should not get any problems with those pictures.

History
~~~~~~~
V2.4 (22.05.1994) :
- fixed bug, which caused the last 4 Bytes of the ColorMap not to be read
(last two Colors have been wrong, then).
This did not concern grey-scaled Files without own ColorMaps ;-)
- fixed the same bug for BitMap data : the last 10 Bytes might not
have been read.
- modified Doc-File slightly to reflect, that 8 Bit-Files are read
correctly (not just since V2.4 ...)
V2.3 (15.05.1994) :
- fixed subtype strings (one blank too much)
(better than nothing, eh ?)
V2.2 (07.05.1994) :
- use of SAS/C V6.51
- use of new "superviewsupport.library" V1
This saves some space again (here : ca. 1100 Bytes).
- version accidentally reflected 2.5 instead 2.1. Now we're at 2.2 :-)
- removed some dead code
V2.1 (17.04.1994) :
- first version
