Displaying a base64-encoded image within an rhtml template
...o display the image: send_data image, :filename => ''fedex_shipping_label.png'', :type => ''image/png'', :disposition => ''inline'' That works fine, but I''d like to be able to set some html/css parameters on it so that it prints at 200dpi, 4x6 inches (the RMagick ''resample'' method wasn''t working for me). I don''t really want to save the label as a file, either. Is there a way to send a variable to the template (e.g., @image) so that it gets rendered as an image? Thank you! -Kyle --~--~---------...

saving graphics in jpeg format
Dear R users, I need to save a graph in jpeg format. After plotting the graph, when the graphics window is active, in the File menu, the Save as / Jpeg / 100% quality correctly saves the graph in jpeg format. But I would like to know, how could I control the resolution (in dpi) of the saved jpeg file? I need to produce a jpeg at 1200 dpi. I have tried also the jpeg function in the package
