PNG image exported by ExportTo REST API is small/blurred

latearrival — Thu, 14 May 2020 05:58:15 GMT

I'm using the 'Reports - Export To File' API (https://docs.microsoft.com/en-us/rest/api/power-bi/reports/exporttofile) to produce a PNG of a report.

The resulting PNG is so small (378 x 548) and blurred that the report isn't useable.

Can anyone tell me how to get a larger/sharper image?

(EDIT - When using ExportTo to export to PDF, the PDF comes out perfectly - the right size and nice and sharp).

Hi @latearrival ,

What is the size of page? It seems does not the common 16:9 or 4:3, does there any custom height and width applied? we test with a 16:9 page and it return a 1280*740 PNG different, does this page is set as "Actual Size"?

Update : We try to use the Actual Size and get similar result as yours, could you please try if it can export as desire when set "fit page"?

Best regards,

Hi @v-lid-msft

In desktop, my page size is set to Custom: 746 width x 1056 height. This is an A4 ratio.

I'm new to Power BI, where do I set "Fit to page", please? Is this a desktop or an app.powerbi.com setting?

Hi @latearrival ,

It can see either in desktop or service, check it in deskto: "View" - “Page View"

Best regards,

Changing View to 'Fit to Page' worked. Thank you!

Do you think this is a bug? It seems strange that a 'View' setting should impact the size of the export PNG. Exporting to PDF worked perfectly when the View was set to 'Actual Size'.

Hi @latearrival ,

It is a strange behaviour, because actual size seems should output the same size, we will confirm if it is an issue later.

Does the export to PDF work when set as "Fit to page" on your side?

ExportTo PDF

- OK when View is 'Fit to Page'.

- OK when View is 'Actual Size'

ExportTo PNG:

- OK when View is 'Fit to Page'.

- Too small when View is 'Actual Size'

I'm sorry, but I don't think I can help. The report we're exporting to PNG is a single page report.
