PImage and renderer

Hi all,

I am designing a GUI and I have some images that I use (all in .png)
I am using the default renderer in processing because I have designed some buttons and their quality looks good (below). However, the images look very sharp (like the logo below)

Is there a way to blur or smooth the sharpness on the PImages?
If I switch to P2D the logo becomes more appealing but the button loses the quality that I desire :frowning:

Thanks in advance!
