Highest-quality printed graphics with exportgraphics
显示 更早的评论
exportgraphics(fig, 'output.tif') % raster format
exportgraphics(fig, 'output.pdf', 'ContentType', 'vector'); % vector format
What are the best options I can add to exportgraphics to get the highest-quality printed graphics, both for raster and vector graphics?

For vector images only the contents of your figure matter: do you have raster images (e.g. with imshow or image)? If so, saving as vector image will not magically convert them and you're stuck with the native resolution of those elements.
For raster images you can set the DPI with the resolution parameter. The default is 150, but I would suggest using 300 as your default (and 600 if you really want high resolution). Take care of the font size, you might need to increase it by 25% for some software due to stupid technical reasons.

For vector images that command should give you the highest possible quality (unless there are rasterized elements in your figure).
For raster images, the command you showed gived a DPI of 600. I don't know what the limit is, but a higher DPI will result in a higher quality until the limits imposed by the Matlab renderer, your OS, and your graphics driver. I expect the limit is higher than 600 for most cases (perhaps around 1e3), but the gains in quality after 600 are marginal, while the file size will keep increasing. I would say 600 is a good balance between excellent quality and not yet excessive file size.
In short: yes. Glad to be of help.
