Hello @Braunstein,

I was inspired by your topic and shared code in the Gallery:  
_[Processing PGraphics Image Scaling and Renderer Test](https://discourse.processing.org/t/processing-pgraphics-image-scaling-and-renderer-test/48944/1)_

_Tatooine_ came to mind and I found the image (classic scene) I was remembering:

I saw the first movie in the theatre! Good memories.

I have done similar in the past and have encountered the same performance and other issues.

1. JAVA2D uses CPU rendering; `image(pg, a, b, c, d)` resizing is slow for a PGraphic.

2. P2D uses GPU rendering; `image(pg, a, b, c, d)` resizing is faster for a PGraphic.

3. In JAVA2D you can also copy the _PGraphic_ canvas directly into a _PImage_ and _resize_ which is faster than 1:

```auto
    PImage target = pgSun.get();  
    target.resize(900, 900);
    image(target, 0, 0);

```

It was getting late so scrutinize and test the content provided.

Have fun!

`:)`
