Details:

After running the following script for fig1.svg I get 494x370 pt and for
fig2.svg I get 560x420 pt while for fig1.png I get 1029x772 px and for
fig2.png I get 560x420px. I can see that there is a difference in displayed
font size (in figure window) and in saved images, also in fig2.svg font size
is not 18pt. Are those expected results?


pos = [300 200 560 420];
figure(1,'paperunits','points','papersize',pos(3:4))
plot([0,1],[0,1]);
set(gca,'fontunits','points','fontsize',18,'FontName','Arial');
print('fig1.svg','-dsvg');
print('fig1.png','-dpng');
print('fig2.svg','-dsvg',['-S' num2str(pos(3)) ',' num2str(pos(4))],'-F:18');
print('fig2.png','-dpng',['-S' num2str(pos(3)) ',' num2str(pos(4))],'-F:18');

get(get(f,'Parent'),'screenpixelsperinch') % ans = 81.597
