Hi all,
I tried to use IDL to export my image result as pictures using plot.save(image.save). But the resolution of result picture always is 96dpi no matter how I change the resolution keyword. Anyone can help?
Thanks,
Jie

David Fanning wrote something about this a while ago, but I cannot seem to find it. You can find examples of a fix in his plot gallery, e.g. at the end of this page

https://www.idlcoyote.com/gallery/additional_axes_plot_fg.pr o

Basically, you create a giant image, then resize it.
