Details:
This affects Octave 4.0.0 on Windows 7 64 bit installed as 32 bit Cygwin
package.
Printing the a plot with the default renderer and the following script leads
to two problems:
* cropped images
* broken pipe or similar errors when omitting the sleep between prints which
leads to image test02.pdf not being generated
When setting the graphics_toolkit to "fltk", the images are produced correctly
but with broken pipe for the print without sleep.
myPaperSize = [30, 10];
myBorder = [1, 1];
data = rand(50,1);
#graphics_toolkit ("fltk");
plot(data);
#set(gcf,"paperunits","inches");
set(gcf,"paperunits","centimeters");
#set(gcf,"paperpositionmode","manual");
#set(gcf,"paperorientation","landscape");
set(gcf,"papertype","<custom>");
set(gcf,"papersize",myPaperSize);
set(gcf,"paperposition",[myBorder, myPaperSize-myBorder]);
title ("Plot 01")
xlabel "Timestamp [samples]";
ylabel "Interval [ms]";
sleep(1);
print "test01.pdf" -dpdf
sleep(1);
print "test01.png" -dpng
clf;
plot(data);
title ("Plot 02 without sleep")
print "test02.pdf" -dpdf
print "test02.png" -dpng
The images have the correct aspect ratio and correct size (PDF), but the image
contains only about one quarter (upper left corner) of the plot.
I can see the plot window temporarely being resized to the correct aspect
ratio and I see the full plot inside the image. But during export as PNG (PDF
has the same problem) the image gets cropped and only about a quarter of the
image gets saved.
The execution of the script above in a file named plotsize.m produces the
following error on the prompt:
$ octave plotsize.m
warning: print.m: fig2dev binary is not available.
Some output formats are not available.
