Make 2x or 3x grafana-image-renderer plugin by default (installing it from source)

Grafana Configuration
1

Hi,
I’m running Grafana on a Raspberry PI 5, and I’m using grafana-image-renderer compiled from GitHub but I’d like to have the image renderized @2x by default.

I know nothing javascript but checking the files I went able to make it renderizing more long and large than default value (3000px) by editing maxWidth maxHeight variables inside the file grafana-image-renderer/src/config/rendering.ts

export const defaultRenderingConfig: RenderingConfig = {
  chromeBin: undefined,
  args: ['--no-sandbox', '--disable-gpu'],
  ignoresHttpsErrors: false,
  timezone: undefined,
  acceptLanguage: undefined,
  width: 1000,
  height: 500,
  headed: false,
  deviceScaleFactor: 1,
  maxWidth: 30000, // from 3000
  maxHeight: 30000, // from 3000
  maxDeviceScaleFactor: 4,
  pageZoomLevel: 1,
  mode: 'default',
  clustering: {
    monitor: false,
    mode: 'browser',
    maxConcurrency: 5,
    timeout: 30,
  },
  emulateNetworkConditions: false,
  verboseLogging: false,
  dumpio: false,
  timingMetrics: false,
};

But if I change the other values like width, pageZoomLevel etc… and after I run again yarn run build it keeps render image @1x and 1000px width even if I changed these values.

I also checked inside the grafana.ini but also changing

rendering_viewport_device_scale_factor =

to any value, recompiling and relaunching grafana-image-render and grafana-server… nothing changed again.

I know that I can write inside the url/query the scale factore but every time I want to render a panel using the share menu, I have to edit the url and render it again. It’s pretty annoying.

I hope there’s another way!

Thanks.
