Hi,
I'm starting to get very frustrated about the print tools in Matlab. To illustrate my problem, I have the following code

I = rand(200,250,3);
imshow(I);
set(gcf,'PaperUnits','points');
set(gcf,'PaperSize',[250 200]);
print(gcf,'test.pdf','-dpdf');

i.e. I plot something with imshow, set the paper size to be 250 x 200 points and then print to 'test.pdf'. When I check the pdf in Acrobat Reader the size is 70.6 x 70.6 mm corresponding to 200 x 200 points.

Why is the paper size set to 200 x 200 instead of 250 x 200 as I have specified? If I fiddle around with the specified paper size, sometimes I get the correct size and sometimes I don't.

Any help is most welcome!
Regards,
Fredrik

It seems that the pdf printer does not process the PaperSize settings properly. A workaround is to create an eps file first, and then convert it to pdf, e.g.:

function exportFigure(fileName, resolution)

print('-depsc2', sprintf('-r%d', resolution), [fileName '.eps']);
system( ...
sprintf( ...
'epstopdf --gsopt=-dPDFSETTINGS=/prepress --outfile=%s.pdf %s.eps', ...
fileName, fileName));
system(sprintf('del %s.eps', fileName)); % delete temporary .eps file

end
