Contour Plot to Image.jpg
24 views (last 30 days)
I need to know how to save or export a 2D Contour plot into an Image file (preferible with .jpeg extension).
I would like also to be able to specify the output location (the folder where the image will be saved), I have tried with this:
But then it appears the following error message:
??? Error using ==> save
Unable to write file name_of_my_image.fig: permission denied.
Any idea about how to do it?. Thanks!

I would not use jpg format. I never create JPEG images. JPEG can/will degrade your image. Use PNG instead.
What does this report in the command window if you call it just before hgsave:
You probably can't save to that folder.
Anyway, even if you get that solved, I'd take a look at the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_save_my_figure.2C_axes.2C_or_image.3F_I.27m_having_trouble_with_the_built_in_MATLAB_functions.

You need to save it somewhere else or have write-permissions for that directory. You could change the directory settings, or run MATLAB as an admin (on Windows right-click the icon, run as admin).
