Hello,  
I am trying to understand some processing 2 existing code. I run into  
duplicateDraw();  
This does not seem to appear in the reference. Can anyone help me figure out what it does?  
I thank you in advance

Here is a partial copy of the code:  
void superbaReadPatternFromScreen(int offset) {  
// moveRowInGUI(); ??  
duplicateDraw();  
loadPixels();

myPattern = “”;  
…  
I doubt this might help. The complete code is available here: [https://github.com/knitty/gui](https://github.com/knitty/gui).  
The duplicateDraw() is in the tab kmsuperbasinger.  
I thank you very much for your help.

Found the solution. It is defined somewhere in the code in another tab!..

Very descriptive function name but unfortunately it didn’t help at the end. Or maybe it did?
