I think the code you posted might not be the working code since a, b and c don't seem to exist in it. :P
Check out the docs for the createImage(int, int)<http://docs.oracle.com/javase/7/docs/api/java/awt/Component.html#createImage(int, int)> method: *Returns:**an off-screen drawable image, which can be used for double buffering. The return value may be null if the component is not displayable. This will always happen ifGraphicsEnvironment.isHeadless() returns true.* It seems you have to make the JFrame visible in order to get an image when using that method. The following should work: *(let [frame (doto (JFrame.)* * (.setSize 100 100)* * (.setVisible true))* * height (.getHeight frame)* * width (.getWidth frame)* * image (.createImage frame height width)] * * image)* Cheers, Juan On Tuesday, January 8, 2013 11:38:35 PM UTC-3, Jacob Goodson wrote: > > (let [frame (doto (JFrame.) > (.setSize 100 100)) > height (.getHeight a) > width (.getWidth a) > image (.createImage a b c)] > image) > > Why does this return nil? > > Thank you! > -- You received this message because you are subscribed to the Google Groups "Clojure" group.
