If I print to a .eps file, I expect that the bounding box of the figure will be fairly tight around the figure so that it may be included directly in another document without a lot of extrawhitespace surrounding it. I think that is most useful. I also don'texpect to have to fiddle with paper properties to make that happen (how would I know that 6.4x4.8 inches are good values?). Earlier versions of Octave did not add extra whitespace around thefigure, so I think we will see a lot of complaints about this changeif it escapes into a stable version.What is the motivation for the change? Is there something good aboutthis design choice that I'm missing? If the change is purely forMatlab compatibility, then I think this is one of those things that weshould not copy. jweThe current implementation produces compatible behavior ... except that the BoundingBox defined by gnuplot is not tight, and the one produced by Matlab is. The current implementation may be modified to obtain the desired result by changing the papersize for the eps output to ... papersize = paperposition + [50, 50, 100, 100]/72;Where the paperunits are implied to be "inches". The 50pt border is agnuplot feature. I'll prepare a changeset. Benfrom people used to the old style. Of more immediate concern to me, there are 22 figures in the Octavedocumentation that are auto-generated by Octave code. The output formatis png for the HTML documentation and pdf for the pdf documentation(Duh!). Under the old code these figures slipped into the text nicely but they now have about 1/3 of a blank page above and below them. If itis certain that this is the new format for the print command I will re-code the figure generation scripts to include all of the papersize-setting commands above. If there is an option to flipMatlab-compatability on or off I would prefer to use that and not changethe scripts. Cheers, RikRik,I certainly get all the credit for this problem. I was focused on the goalof compatibility with Matlab and didn't consider the documentation.In any event, I think the best solution would be one that is compatible withMatlab, and is simple to implement.My first thought was to run the lines below prior to producing the figuresfor the documentation. image_size = [6.4, 4.8]; % in inches border = 0; % For postscript use 50/72 set (0, "defaultfigurepapertype", "<custom>") set (0, "defaultfigurepapersize", image_size + 2*border)set (0, "defaultfigurepaperposition", [border, border, image_size])This *should* produce pdf files at 6.4x4.8 inches. Unfortunately, these defaults are not passed onto the figures :-(Even so, as the defaults not set for the figure is a bug, I recommend thissolution.Rik, do you know enough c++ to take care of setting the figure's defaultproperities? (I don't).you would have to change the following 2 functions in src/graphics.cc: default_figure_papersize default_figure_paperpositionalso, in src/graphics.h.in, you would have to change the line which has:radio_property papertype , "{usletter}|uslegal|a0|a1|a ..." and move the curly brackets to surround <custom> instead of {usletter} Shai
Hi Shai, opps, I wasn't clear.I don't want to change the defaults for all octave sessions, only for the one that is running.
For example, the default axes fontsize can be set from the command line by ...
set (0, "defaultaxesfontsize", 18)Then new axes will then have the tick labels with size 18pt. For example ...
octave:1> plot (1:10) octave:2> get (gca, "fontsize") ans = 12 octave:3> set (0, "defaultaxesfontsize", 18) octave:4> figure octave:5> plot (1:10) octave:6> get (gca, "fontsize") ans = 18 Ben
