I have Matlab code (too complex/inelegant to post or attempt to simplify) that produces an array of subplots that looks like this:
When I save this as an EMF file and insert in Powerpoint, then zoom in closely on the image, it looks pixelated:
This is very surprising to me, as I have for a long time been exporting Matlab plots as EMF and integrating those into Powerpoint slides, in order to build there more complex graphs that, as vector graphics, would print well at any size. These imported EMFs would also scale well and look smooth regardless of how much I zoomed into them in Powerpoint.
Opening the EMF in Inkscape shows that this plot is indeed exported by Matlab not as vector but as raster graphics. Can anyone guess why that is? Thanks in advance!
