Details:
Task: Saving a figure to .png as it appears on the screen, using both size and
resolution options (e.g. -S800,500, -r600).
Result: While both Options alone work, setting them together overwrites the
rsolution with 72.
Example code:
figure(1,'Position',[100,100,800,500]);
plot(randn(100,2))
title('test'); ylabel('y axis'); xlabel('x axis');
pos=get(gcf,'Position');
print('-dpng', 'test.png',
'-r600',['-S',num2str(pos(3)),',',num2str(pos(4))]);
The output is of very much lower resolution, probably 72 (cf. below).
The problem may be related to code in the function
scripts/plot/util/private/__print_parse_opts__.m, where it says around line
367:
arg_st.ghostscript.resolution = 72;
Simply commenting out this line, the output looks as expected. However, this
is probably not the solution for all cases.
