Maker Interchange Format (MIF) driver Version 1.03
I've made a few substatial updates to my device driver that creates a MIF file from IDL plot commands, so here it is. The highlights include: -- Finally report out text width (man, what a pain!). Requires Environment variable FMHOME to be defined; not sure of portability problems with that...may need ifdef's in code to handle other OS's. If it can't find the font metric files, it assumes it is a fixed-width font, so it stays roughly right. This feature was implemented so that XYOUTS,width= works, which is important to routines like LEGEND. -- Changed resolution to 0.2pt to reduce need for extra decimal place in coords. -- In plotting, if a subsequent point in a line is at the same location within the 0.2pt resolution it is skipped. This shortens the file somewhat and may reduce some problems with dashed line styles. See the README for further details and implementation notes. #! /bin/sh # This is a shell archive. Remove anything before this line, then unpack # it by saving it into a file and typing "sh file". To overwrite existing # files, type "sh file -c". You can also feed this as standard input via # unshar, or by typing "sh <file", e.g.. If this archive is complete, you # will see the following message at the end: # "End of archive 1 (of 1)." # Contents: README Makefile frameimage.h mif.c # Wrapped by ryba@ulna on Tue Jan 30 16:15:16 1996 PATH=/bin:/usr/bin:/usr/ucb ; export PATH if test -f 'README' -a "${1}" != "-c" ; then echo shar: Will not clobber existing file \"'README'\" else echo shar: Extracting \"'README'\" \(6358 characters\) sed "s/^X//" >'README' <<'END_OF_FILE' X X IDL device driver for Maker Interchange Format (MIF) X X Version 1.03 - 30 January 1996 X X Martin Ryba, MIT Lincoln Laboratory X ryba@ll.mit.edu X X X IDL can link in routines from sharable object libraries via the XLINKIMAGE command. In this manner, new graphics device drivers can Xalso be added. This is a driver for Maker Interchange Format, an XASCII format used by FrameMaker(TM) from Frame Technology Corp. Using Xthe MIF driver allows one to create an IDL graph that becomes an Xeditable part of a FrameMaker document, allowing one to change the Xproperties (colors, line styles, fonts, tick marks, etc.) of the Xgraphic without re-running the IDL .pro file that generated it. Also, Xthe graphic elements position and size are visible at full resolution, Xunlike the low-res monochrome bitmaps available under the Encapsulated XPostScript Interchange (EPSI) format driver. X XTo use the driver within IDL: XIDL> linkimage, 'mif_dev', 'mif.so', /device XIDL> set_plot, 'mif' X XReplace 'mif.so' with the full pathname of the shareable object Xlibrary. The linkimage command is of course easily added to your Xstartup file. X X This driver supports nearly all the keywords and features of the XPostScript driver with IDL. The default line thickness is 1pt (as Xopposed to the too-thin ~9/32 pt used by the PS driver). The default Xgraphic size is 6.5"x6.5", though that can be changed via the X{X,Y}SIZE keyword. There are no offset keywords since these MIF files Xare meant to be incorporated into other documents. If they are simply Xopened and printed in FrameMaker, the graphic will be centered on the Xpage with landscape or portrait automatically chosen depending on the Xdimensions of the plot. Color images (scalable pixels) are supported, Xand lines and polygons can be created in any of the eight FrameMaker Xstandard spot colors: black, white, red, green, blue, cyan, magenta, Xand yellow. IDL linestyles are supported, and polygon fill patterns Xvia the FILL_PATTERN keyword of POLYFILL are supported (FrameMaker Xsupplies 16 fill patterns, though fill 15 (none) isn't very useful in Xthis case). There may be a problem using this driver with POLYSHADE, Xsince I haven't done polygons in arbitrary colors. To use it, I would Xsuggest using the Z-buffer device to create a bitmap image which is Xthen rendered into the MIF file via the TV command. X X A note on dashed line styles...since I don't have any logic in Xthe driver to measure how far along a given line I've traveled, I've Xnoticed that if the points are closer together the dashes won't show Xup, since FrameMaker wants to show each vertex of a PolyLine, even for Xa dashed line style. I've found that selecting the object in Frame Xand then choosing the "Smooth" option from the Graphics menu will make Xthe dashes show up without too much change to the nature of the line. X X All 35 standard PostScript fonts are supported, as well as the X!-escapes for changing fonts; font !20 can still be an arbitrary Xuser-defined font. Superscripts and Subscripts are supported via the X!U and !D escapes (other subscript sizes and levels (!A, !B, !E, !I, Xand !L) are not supported). Save and restore of positions (!S and !R) Xare not supported. The !MX bullet is not supported; instead use !B or Xstring(165b). The character set is the Frame Character set described Xin Appendix B of the User's Guide. Below is a list of the supported Xkeywords of the DEVICE procedure and their functions: X XAVANTGARDE - select ITC Avant Garde PostScript font XBKMAN - select ITC Bookman PostScript font XBOLD - select bold version of current font (if available) XBOOK - select book version of current font (if available) XCLOSE_FILE - close current MIF file. Resets the file name to the X default idl.mif XCOURIER - select Courier PostScript font XDEMI - select demibold version of current font (if avail.) XFILENAME - set the current MIF file name XFONT_INDEX - see PS driver description (3-26 of Ref. manual) XFONT_SIZE - set default font size (normally 12pt) XHELVETICA - select Helvetica PostScript font XINCHES - {X,Y}SIZE values are in inches XITALIC - select italic version of current font (if avail.) XLIGHT - select light version of current font (if available) XMEDIUM - select medium version of current font (if avail.) XNARROW - select narrow version of current font (if avail.) XOBLIQUE - select oblique version of current font (if avail.) XPALATINO - select Palatino PostScript font XPOINTS - {X,Y}SIZE values are in points (1/72 inch) XSCHOOLBOOK - select New Century Schoolbook PostScript font XSYMBOL - select Symbol PostScript font XTIMES - select Times Roman PostScript font XUSER_FONT - scalar string containing name of a PostScript font. X Font must be specified exactly as PS printer X expects. May require some FrameMaker setup. XXSIZE,YSIZE - Set size of drawing area. Default is cm, but see X INCHES and POINTS keywords. XZAPFCHANCERY - select ITC Zapf Chancery PostScript font XZAPFDINGBATS - select ITC Zapf Dingbats PostScript font X X X Notes on installing: X X1) The Makefile is tuned for SunOS 4.1.3 using the SunPro ANSI C X compiler. Other compilers, linkers, and operating systems are your X problem, since I don't have anything else to test on. Naturally, X I would be willing to archive other Makefiles and other portability X enhancements. I guess a "configure" script would be the ultimate. X X2) Note the use of the -assert nosymbolic loader directive. I've X found it to be necessary for shared objects that contain static X data structures. This way, no .sa file is needed. However, there X might be conflicts with mulitple IDL sessions on the same machine X using the MIF driver simultaneously. X X Comments, suggestions, bug reports, bug fixes, etc. are welcome, Xthough they will be acted upon as I'm able. X X X**** CHANGES ******** XVersion 1.03 - 01/30/96 - Finally report out text width (man, what a pain!). X Requires Environment variable FMHOME to be defined; not sure of X portability problems with that...may need ifdef's in code to handle X other OS's. Changed resolution to 0.2pt to reduce need for extra X decimal place in coords. X XVersion 1.02 - 01/11/96 - Don't add point in continuing line if start and X stop points are identical. FONT_SIZE bugfix. X XVersion 1.01 - 07/10/95 - Small bugfixes for fill, page number, !-escape X handling, and added debugging prints.
