Hi

please check [https://openprocessing.org/sketch/1197450](https://openprocessing.org/sketch/1197450)

Colors are missing, why? Is something missing on [openprocessing.org](http://openprocessing.org)?  
Code works fine on my machine.  
I am sure it is something silly, but I don’t see what.  
Thanks

Hello,

Works with odd numbers on the Open Processing version!

```auto
// Set the display pixel to the image pixel
int div = 5;	//Seems to display correctly with odd numbers.
pixels[loc/div] = color(r, g, b);

```

More exploration is needed…

I see, /5 fixes things indeed, thanks. No idea why.

ps. I know that Processingjs is deprecated, but somehow I need a quick cut&paste.

You can also add `| 0` after each division `/` operation, so its result is truncated: ➗  
`pixels[loc/4] = color(r, g, b);` → `pixels[loc/4 | 0] = color(r, g, b);`
