Exporting paginated report to PNG with Rest API seems not to provide consistent anti aliasing

[FrançoisD]

Hello,

We are currently facing an issue with the https://learn.microsoft.com/en-us/rest/api/power-bi/reports/export-to-file#exportreportsettings endpoint.

The result it outputs when we ask for PNG image is not totally consistent, especially for charts. Legend & borders are not aliased the same way leading to differences between the images. The issue is that our automation is trying to find out the differences between two snapshot to ensure that for the same parameters we always have the same render after we, for example, changed the DB.

Ths can be seen in those three snapshots: 

The first snapshot

The second snapshot, few hours later

And if I ask the difference to Gimp, I get :

To summarize:

- table is properly rendered

- chart header is properly rendered

- chart itself with all text are not aliased the same way.

Is there a way to force the aliasing to be consistent from our side?

Regards
