- 1. This software (and its documentation) is copyrighted; please see the
- documentation for details. (Don’t panic: it’s free...)
-
- 2. I don’t think mkdrawf will work under RISC OS 2, because it uses
- FontManager calls that didn’t exist then (for calculating text
- bounding boxes). If you have RISC OS 2, you can replace the
- relevant code with something more simple-minded -- copy the code
- that’s used when an undeclared font is found. Of course, some of
- the drawfile object types aren’t understood by RISC OS 2’s !Draw,
- but that’s a different matter...
- decdrawf should be completely OK with RISC OS 2.
- !Drawf uses some RISC OS 3 calls, but not (I think) so essentially
- that you couldn't make it work under RISC OS 2. For this you will
- probably want the source for o.glib -- ask me.
-
- 3. What follows is a brief “map” of this distribution.
-
- ----------------------------------------------------------------------------
-
- Source
- ------
-
- contains source code, of course.
-
- Source.c
- Source.h
- Source.o
- Source.s
- are just what you’d expect (.s is assembler)
- and contain the complete source code, and object files for
- the machine-code bits (so you don’t need an assembler).
-
- Source.mdkrawf
- Source.decdrawf
- are the actual programs (so you don’t need a compiler or assembler).
- You should move them to somewhere in your Run$Path.
-
- Source.Makefile
- is, erm, a makefile. You may need to change some of the definitions
- at the start.
-
- Doc
- ---
-
- contains documentation.
-
- Doc.ManualI
- Doc.ManualT
- Doc.ManualP <-- not actually included!, but I can send it to you
- contain basically the same material, except that some illustrative
- drawfiles aren’t in ManualT. In order these are in Impression format,
- plain text and PostScript.
- Incidentally, if you try to print out ManualI on a laser printer
- you are likely to have trouble, because many can’t cope with the
- length of the path in the snowflake curve example. I can tell you
- how to get round this.
-
- Doc.TutorialI
- Doc.TutorialT
- Doc.TutorialP <-- like ManualP, nonexistent
- contain a fairly gentle introduction to the use of mkdrawf and
- decdrawf. If you find the manual heavy going, you might like to
- try this.
-
- Doc.DrawfI
- Doc.DrawfT
- Doc.DrawfP <-- guess what?
- contain documentation for !Drawf, a Wimp front end for mkdrawf and
- decdrawf. This is short, and it won’t take you long to read it.
-
- Doc.Changes
- contains an entry for every new version since 2.20, saying what's
- changed. It's more for my convenience than yours :-).
-
- Doc.Credits
- is just what you think it is.
-
- Doc.Custom
- tells you a bit about how to proceed if you want to make changes
- to mkdrawf.
-
- Examples
- --------
-
- contains the mkdrawf source for the examples in the manual, and also
- some drawfiles to decode with decdrawf to see the sort of output it
- produces. There are also several more example source-code files.
-
- Examples.src
- is mkdrawf source code.
-
- Examples.draw
- is for drawfiles.
-
- Examples.dec
- is a good place to put decoded drawfiles. I suggest here rather than
- .src, so that if you decode something you created with mkdrawf you
- don’t overwrite the original source.
-
- Examples.Makefile
- is a makefile, to save you a bit of typing.
-
- Goodies
- -------
-
- contains a couple of programs that produce mkdrawf code. You could
- implement these completely in mkdrawf, but (1) it’s nicer in a better
- programming language, and (2) I wrote them before mkdrawf had any
- programming features.
-
- It also contains a useful program to compute the intersection of two
- lines. Of course this really could be done in mkdrawf code, and that
- might be a better way in most cases, but...
-
- Goodies.c.dodec
- Goodies.c.icos
- produce, respectively, a dodecahedron and an icosahedron. Each
- should be called with 3 command-line arguments, which are rotation
- angles in degrees. Experiment!
- Goodies.c.icosi
- is an interactive version of icos, which displays its output on
- the screen and allows you to change the parameters.
- Goodies.c.intersect
- takes 8 numbers (4 pairs of coordinates) and computes the intersection
- of two lines. The args should be given in the order
- line-1-point-1-x line-1-point-1-y line-1-point-2-x line-1-point-2-y
- line-2-point-1-x line-2-point-1-y line-2-point-2-x line-2-point-2-y .
-
- Goodies.o
- is an empty directory to put object files in if you recompile these.
-
- Goodies.dodec
- Goodies.icos
- Goodies.icosi
- Goodies.intersect
- are the executables produced from the above, in case you don’t have
- a C compiler.
-
- !Drawf
- ------
-
- is a Wimp front end for mkdrawf and decdrawf. You can just double-click
- on the icon to run the program. Inside...
-
- !Drawf.Source.c
- contains the C source code for !Drawf.
-
- !Drawf.Source.o
- contains `o.glib', a small library which contains some rather low-level
- functions for interacting with the Wimp. (Most are basically just SWI
- veneers.) If you want the source code for this, ask me.
-
- !Drawf.Source.h
- contains header files for the stuff in o.glib.
-
- !Drawf.Source.Makefile
- is a makefile. Amazing. You won't be able to use it to re-make
- o.glib, because you don't have the source code.
-
- !Drawf.Run
- !Drawf.!RunImage
- !Drawf.!Sprites
- !Drawf.Sprites
- !Drawf.Templates
- are just what you think they are.
