Figure print - resolution stays at 96 dpi, despite specifying a higher resolution

Hello Everyone,

I'm experiencing a strange problem when saving a figure as jpg. I want to save the figure at a resolution of 500 dpi. For this purpose I'm using this function:

print(h,'-djpeg','-r500',file_name);

However, the figure is always exported at a fixed resolution of 96 dpi (this is what is shown when I look at the figure's properties). Before 'printing' the figure I've already configured paper size, figure size, etc., and it all works well, but the resolution is the one thing that doesn't work.

Any help in finding out what could be causing this and how it could be solved would be greatly appreciated!

Thanks in advance,

Susana

Hi Susana,

just a question: do you see any effect? I just tried it (again), and using '-r150' and '-r300' indeed doubled the resolution (number of pixels in x/y). This is what I tried

surf(peaks);
print('-djpeg', '-r150', 'file150.jpg')
print('-djpeg', '-r150', 'file300.jpg')
