I recently updated from a 2013 version to 2015a. For years, going back to 2011, I've been using

print(gcf,'-dmeta')

to copy figures to the clipboard, after which I paste the figures into powerpoint. With my previous MATLAB version the file size was roughly 30 KB per slide, but with 2015a, the file size has jumped to ~360 KB per slide. This new size is unsustainable with the files I have to generate. Changing the resolution of metas with anything similar to

print(gcf,'-dmeta','-r75')

has no effect. I've had mild success with switching to dialed-down bitmap

print(gcf,'-dbitmap','-r75')

but to get down the previous file size, I have to drive the visual quality down to something considerably worse than with the default -dmeta with 2013.

Is there a workaround to get back to the 2013 -dmeta functionality and file size?

Thanks

Try this:

[image,path]       = uigetfile('*.*');
info               = imfinfo(fullfile(path,image))

check the differences?

imfinfo doesn't appear to work for .emfs, however, it does work for .pngs. Saving the images out of the generated powerpoints, I actually get 1,630 KB for the 2015 .emf, 283 KB for the 2013 emf, and 150 KB for the low-res .bmp.

One observation: The plot lines, ticks, and boxes look similar in the powerpoints for 2013 and 2015, but when I then save the .emfs out of the presentations, the 2013 lines, ticks, and boxes are much thinner/fainter than with 2015.
