-
- 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
