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

Recommended Posts

Dear Affinity support team,

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


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,
