Re: orient tall with fltk

[Jose]

Hi.

I am still a bit lost and I'd like to learn what I am doing wrong. 
Please, let me know where I make the mistake in my line of thought. 
Thanks in advance for your patience.

Let me recap, as I might have not been clear with my problem. My goal is 
to produce a print in pdf (ultimately with pdflatex, and that is why 
fltk is a must) with small margins, that is: a paper filled with the 
figure. The orient command can be used for this, as it is supposed to 
orient the paper and scale the figure to fit the page with a 0.25 inch 
border.

Using orient with gnuplot works nicely, whereas with fltk it does not, 
as the figures are not scaled properly to fill the paper.

What somehow works is to adjust manually the sizes of the figure and the 
paper so that they are the same, making sure that the size fits in the 
screen. In this sense one can first define the size of the paper first 
and then adjust the size of the figure or viceversa. For example:

*Adjusting the size of the paper to the size of the figure:
 ----
 clear all;graphics_toolkit fltk;
 plot (rand (3))
 fig_size=get(gcf,'position')(3:4); %in pixels
 paper_size=fig_size/72; %in inches, gives [7.7778 5.2778]
 border = 0;
 set (gcf,'papertype', '<custom>');
 set (gcf,'paperunits', 'inches');
 set (gcf,'paperorientation','landscape')
 set (gcf,'papersize', paper_size);
 set (gcf,'paperposition', [border, border, (paper_size - 2*border)]);
 print foo1.pdf
 ---

*Adjusting the size of the figure to the paper
----
clear all;graphics_toolkit fltk;
paper_size=[10 6]; %in inches
border = 0;
set (gcf,'papertype', '<custom>');
set (gcf,'paperunits', 'inches');
set (gcf,'paperorientation','landscape')
set (gcf,'papersize', paper_size);
set (gcf,'paperposition', [0, 0, paper_size]);
fig_size=(paper_size-2*border)*72;%in pixels
set (gcf,'position',[0 0 fig_size]);
plot (rand (3))
print foo2.pdf
---

The results are similar in both cases, and although better than using 
orient, the figure has still somehow large margins even with border=0. 
Compare the attached foo1.pdf with foo3.pdf, which was generated using 
the same code but with gnuplot instead of fltk.

Yes, that is what I will do if I don't find a solution from within 
octave. I will print to a pdf, use for example pdfcrop to automatically 
remove the excess of margins and InkScape to export to latex.

Thanks again for your patience.
