- converting bitmap formats such as GIF, JPEG, TIFF, etc... to NAPLPS
- is not a very good idea although it *IS* possible. NAPLPS is an object
- oriented graphics format like Postscript, metafiles, Corel Draw, etc...
- It does allow for bitmaps but if they are any significant size you
- lose the compactness advantage of NAPLPS. I have only used icon
- bitmaps (I wrote an MSDOS QBASIC program to convert Windows icons.) in
- NAPLPS pictures.
-
- It is best to start with some sort of metafile format. If you can get
- ahold of an older version of Corel Draw (2.0) it will export to
- VideoShow format which is essentially NAPLPS. This export filter was
- not included in Corel Draw 3.0.
-
- I have used VideoShow a bit but it has problems. It basically generates
- polygons with large numbers of straight line edges to simulate curves
- and outlines consist of many *UNCONNECTED* line segments as a separate
- object from the fill. I did succesfully export a filled ellipse and
- was able to import it into Microstar's MGE editor to add it to other
- art. But when I tried a simple horse outline MGE couldn't handle it
- although PP3 would display the graphic. I think the videoshow format
- allows too many nodes in a polygon whereas the NAPLPS standard only
- guarantees to support 256 nodes per object.
-
- I think the most promising approach would be to convert a metafile
- format such as CGM or Windows Metafile but I have not yet taken the
- time to write the code.
