Using updatePixels to speed up a slow applet
Mar 22nd, 2006, 8:14pm  
Hi there,

Is there an easy way to update pixels[] with an image at a specified location?  I appreciate that this can be done with clever useage of for statements (etc), but I am worried that adding an entire image to pixels[] will take some time using this method.  You see, I wish to be able to make use of updatePixels and loadPixels to speed up the running of this full screen applet I have created, where a person selects an image using the mouse, and can then drag that image around the screen (rather jerky at the moment!).  A previous post does offer a solution (see http://processing.org/discourse/yabb/YaBB.cgi?board=general;action=display;num=1104602974), however, the code is quite dated and does not work any more.

Thanks for any help, Andy.
