Does your question relate to JointJS or JointJS+. Select both if applicable.

Hi Orangewithsugar,

The quality parameter only affects the quality when the image is generated with toJPEG(), i.e. it has no effect for toPNG().

The parameter you are looking for is size (https://docs.jointjs.com/api/format/Raster/#size). By default ('1x'), the size of the generated PNG matches the size of the SVG at the time of export. Increasing the value here will make the PNG that much larger (= have that much more detail at zoom). For example, passing in '2x' here will make the PNG twice as large in each direction than the origin SVG.

I tried the option and it works.
