Exported PNG has "Physical pixel dimensions" (pHYs) set

[KerstenB]

Dear Affinity support team,

when editing SVG files and exporting the result as PNG, we noticed that the PNGs have the pHYs section set:

https://www.w3.org/TR/2003/REC-PNG-20031110/#11pHYs

In our case:

pixel_units: meters

pixels_per_unit_x: 5669

pixels_per_unit_y: 5669

 

As we use Affinity Designer for designing icons for several applications, this section must not be set (plain pixel grapic). Some controls of our applications (WPF/WinForms) have problems rendering the PNGs (DPI/scaling issues) when the pHYs section is set. We already tried several exporting options. Ideally, we would export as PNG-8 (dithered) with no ICC profiles embedded and without metadata to achieve the smallest possible file size.

Is this a bug or are there any options we missed?

 

With kind regards,

Kersten

Hi,

I'm afraid there is no way to disable pHYs on export. Sorry.
