The quality of the image worsens when you add overlays with Marker.js2 (compared to the initial quality of the input image) #130

Please have a look at this video: https://www.dropbox.com/s/jigyjdvryj36sgc/marker.js%202%20-%20All%20Defaults%20Demo%20-%20Google%20Chrome%202022-11-14%2015-56-55.mp4?dl=0

And at these 2 images: the first one is unedited and it's higher-quality, the second one is lower-quality as it was processed by Marker.js2.

Is this somehting canvas-specific that doesn't have a workaround?

Thank you, @ailon! Yes, adding `

markerArea.renderAtNaturalSize = true; markerArea.renderImageType = "image/png"; markerArea.renderImageQuality = 1; ` helped!
