Hello to all,
Finally, I have some great progress in the dat->postscript conversion.
I figured out how to use the .dat file and displaying the part. For now my
test part is the tile part (only boxes and lines, 3070.dat). I also managed to
get one of the tile's box into postscript format. So I understandly the basics
of the whole conversion proces.
Here is a very small postscript sample:
% Dat2Ps program Version 0.1 copyright G.Heunen
% 16/11/2000
/Times-Roman findfont
20 scalefont
setfont
newpath
200 200 moveto
(DAT2PS Version 0.1) show

The program is still not final, because I am still not able to do more parts at
once. However I would like to know from the lugnet community what they think
the program should. With this in mind, programming might be easier.
Furthermore, I would like to know the following from Michael.
Could you give me details on the following:
How do you deal with all the *.dat information within a model? (Do you read
just once a part or read them always?)
If you want to change the orientation of the model, how do you erase the old
drawing? (I use a Image component within delphi, but I don't find how to erase
the old drawing when changing the orientation?)
How do you determine what face has to be fully drawn and the bac face/side not?
Could you give me colour specifications MLCad<->RGB(?)?
Why are there the same lines (2-points) corresponding to quadrilateral lines
(4-points) in for example box5.dat? In my postscript example the quadrilateral
(4) are draw but without the filling command. The lines (2)are not in yet.
