Canvas size / dimensions on save


When I create a canvas of 1200*627 and save it (saveCanvas or manually) the dimensions change to 2400 * 1254. I believe this didn’t occur before so I figured it must be something I’ve done that triggered this but with this simple example having the same effect I ran out of ideas.

Can anybody tell me why this is happening, did something change and/or how can I adjust this so that the dimensions stay the same.

If not any of above any information about this would be greatly appreciated.

sketch file:

function setup() {
  let c = createCanvas(1200, 627);
  saveCanvas(c, 'myCanvas', 'jpg');  

Dunno. Maybe use pixelDensity(1);:


I tried it on my W10 PC with the Processing P5.js mode.

It worked for:
/*! p5.js v0.10.2 October 14, 2019 /
Did not try v1.1.8 !
! p5.js v1.1.9 July 22, 2020 */ //I jsut downloaded it and updated my local one.


With this, the download is in the desired dimensions. Although I will keep looking for the cause it is enough to start advancing on my project once again. Thank you!
