Currently, Gdraw supports routines +both in Xwindows functions, and in postscript functions on +a postscript printer/interpreter. + +The general drawing functions are (see file for description of functionality) +\begin{verbatim} + 1.

This file can be submitted to the postsctipt +printer to be printed, or viewed using the postscript interpreter. +It will draw a window, title, and picture clipped to fit inside of the +window. + +In order to generate a postscript output, we first initializ file names and +paths to be used by our program by using +\begin{verbatim} + InitPs(viewWindow, titleWindow) [in GinitPS.c] +\end{verbatim} +then call the G draw routines with option "PS", which would generate postscript +drawing commands. Then create the output file (OUTPUT.ps by default) by using +\begin{verbatim} + makePSfile(viewWindow, titleWindow, title) [in GcreatePS.c] +\end{verbatim} + +The output file would be in local directory, i.e., the directory where Axiom +or viewAlone, etc., was started up. + +The following routines are used to test out the Gdraw functions: +\begin{verbatim} +1. main.c creates windows, and titles and processes Xwindow events. +2. data.c creates data for drawing and call Gdraw routines. +3. menu.c draws menu when mouse clicks in viewWindow +4. yesORno.c determines if mouse click in menu means "yes" or "no". +5. loadFont.c loads font for display +\end{verbatim} + +The Gdraw routines have been written in such a way that they are usable by +both view3D and view2D. + +\subsection{TO USE G FUNCTIONS} + +In order to draw in postscript, use GSetForeground to set the foreground +colors for the drawing (and fill) functions. Use GSetLineAttributes +to set line attributes. And finally, replace the XDraw commands with the +corresponding GDraw commands with the appropriate parameters. In addition, +we need to: draw frame, set GC variable names, create GCs, initialize +postscript data structures, cat all the procedures used together. + +{\bf IMPORTANT}:\\ +In order to create postscript command file, we need environment +variable DEVE (i.e., setenv DEVE /u/jimwen/3D/version28) or AXIOM (e.g., setenv +AXIOM /spad/mnt/rt in case Gdraws directory has been installed on the server). +Without this path, the program would not know where the postscript files (in +Gdraws/PS) are. + +{\bf LIMITATIONS} of current implementation:\\ +A picture is printed with 1 inch x direction, and 1 inch y direction +offset, and the largest complete picutre is the size of the page +with the offest. + +{\bf BUGS}:\\ +The region box is not drawn correctly when perspective is altered. + + +{\bf FUTURE DIRECTIONS}: +\begin{itemize} +\item for view3D color rendering, may want to convert LINE drawing color +to the appropriate grayscale. Right now, they're all drawn in black. +\item for view3D's routines for color rendering, may want to implement +color drawing for postscript functions just in case someone does +have access to a color postscript printer. +\item implement more functionality for attributes used in GC, i.e., dashed +line, dotted line etc. +\item implement a display postscript menu to set things like picture size, +landscape/portrait orientation, picture centered, left, right, up, +down, etc., reversed video. +\item make font an attribute in postscripts's graphics context so the +font can be set in user program. Right now, it uses only 1 font. +\item for view2D's stuff, implement a smaller font for the drawing the +units on the axes. +\end{itemize} + +\section{environment variables} +<<environment>>= +IN= $(axiom_src_srcdir)/graph/Gdraws +OUT= $(axiom_target_libdir) +PS= $(axiom_target_libdir)/graph +DOC= $(axiom_target_docdir)/src/graph + +# local include files shared by graphics +LINC= $(axiom_src_srcdir)/graph/include + +# global include files shared by everyone +GINC= $(axiom_src_srcdir)/include + +# include files in Hyperdoc +HINC= $(axiom_src_srcdir)/hyper + +# bitmaps for cursors +BIT= $(axiom_src_srcdir)/graph/include/bitmaps + +# a .h file stuck in a really wierd place +DOTH= $(axiom_src_srcdir)/graph/viewman + +# a .c file in the library subdirectory +DOTC= $(axiom_src_srcdir)/lib + +pamphlets = Gfun.c.pamphlet psFiles.pamphlet Makefile.pamphlet + +AXIOM_CFLAGS = ${CCF} -I${LINC} -I${GINC} -I$(srcdir) -I${HINC} \ + $(axiom_includes) ${AXIOM_X11_CFLAGS} + +@ +\section{Gdraw code} +\subsection{Gfun} +<<Gfun.c>>= +Gfun.c: $(srcdir)/Gfun.c.pamphlet + $(axiom_build_document) --tangle --output=$@ $< + +@ + +<<Gfun.o>>= +Gfun.$(OBJEXT): ${HEADERS} + +Gfun.$(OBJEXT): $(builddir)/Gfun.c + ${COMPILE} -o $@ $(CFLAGS) $(AXIOM_CFLAGS) $< + +@ + +<<*>>= +<<environment>> + +subdir = src/graph/Gdraws/ + +pamphlets = Makefile.pamphlet Gfun.c.pamphlet psFiles.pamphlet + +HEADERS = ${IN}/Gdraws0.h ${LINC}/G.h ${LINC}/Gfun.H1 \ + ${GINC}/hash.h ${GINC}/hash.H1 ${GINC}/useproto.h \ + $(axiom_c_macros_h) + +PSFiles= ${PS}/colorpoly.ps ${PS}/colorwol.ps ${PS}/draw.ps \ + ${PS}/drawIstr.ps ${PS}/drawarc.ps ${PS}/drawcolor.ps \ + ${PS}/drawline.ps ${PS}/drawlines.ps ${PS}/drawpoint.ps \ + ${PS}/drawrect.ps ${PS}/drawstr.ps ${PS}/drwfilled.ps \ + ${PS}/end.ps ${PS}/fillarc.ps ${PS}/fillpoly.ps \ + ${PS}/fillwol.ps ${PS}/header.ps ${PS}/setup.ps + +.SUFFIXES: +.SUFFIXES: .c .lo .h .ps + +.PHONY: all all-ax all-Gdraws +all: all-ax +all-ax all-Gdraws: stamp + @ echo finished making $(axiom_src_srcdir)/Gdraws + +.PHONY: PSfiles.post +stamp: Gfun.$(OBJEXT) $(PSfiles) + @rm -f stamp + $(STAMP) stamp + +$(PS)/%.ps: $(srcdir)/psFiles.pamphlet + $(axiom_build_document) --tangle=$* --output=$@ $< + +<<Gfun.c>> +<<Gfun.o>> + +mostlyclean-local: + @rm -f Gfun.$(OBJEXT) + +clean-local: mostlyclean-local + @rm -f $(PSFiles) + +distclean-local: clean-local + +@ +\eject +\begin{thebibliography}{99} +\bibitem{1} nothing +\end{thebibliography} +\end{document} |
