Export Persona scales images down by 2x after Export, how to fix?

[Sergej S]

Hello Affinity Friends!

I have a problem. Affinity Designer shrinks my images by 2x when I export them with Export Persona. Normally I slove my issues on my own but this time I cant find the solution. Please help me.
I have attached two pictures.

Big thanks to all of you!

Hi,

Welcome to the Affinity Forums

Firstly, we recommend not using your email address as your username, as otherwise spammers can harvest this address. Can you please confirm for me, what would you like your Username to be here on the Forums? I can manually change this for you.

Secondly, in regards to the issue you're reporting, Slices in Affinity have a setting that allows you to control the exported file size -

Could you please provide a screenshot of the Slices Studio within the Export Persona, with the export format expanded to show this information as above?

Many thanks in advance!

Your document DPI will factor into this, so it would help to know what it is, from the  Document Setup dialog.

@Dan C  Hello Dan! Everything is set to default... when I export any artboard by File>Export it exports in corect resolution.

Hello @walt.farrell! Thank you for your suggestion. Yes you are definetly right. The Resolution can change dipending on DPI. But thats not the right solution increasing DPI hoping to hit corect resolution in the export phase. Do you have an other idea?

It's intentional to help with getting different export sizes depending on screen DPI, I believe.

Just work at anything other than 144 or 288 and I think you'll be OK.

Hey meybe you are right @walt.farrell i tried out to set DPI once to 72 and once to 300 and both got me to right resolution size. Then I tried to set the same file to 144 dpi and got a downscaling to half. Why it is so?

It's in support of Retina displays and to make it easier to create icons for different display resolutions, I think.

But others can explain it better than I.

Thank you anyway. Without you I would never started play around with DPI.

I can confirm this is covered in the Helpfile page for the Export Persona -

When exporting slices via the Export Persona, the slice export size (1x, 2x, 3x, etc.) is linked with your document's DPI. The table below shows how DPI and export size affect export dimensions, using a 64x64 px document as an example.

DPI setting for a 64x64 document	Export dimensions (in pixels); Exported DPI
	1x	2x	3x
72	64x64; 72	128x128; 144	192x192; 216
96	64x64; 96	128x128; 192	192x192; 288
144	32x32; 72	64x64; 144	96x96; 216
192	32x32; 96	64x64; 192	96x96; 288
216	21x21; 72	42x42; 144	64x64; 216
288	21x21; 96	42x42; 192	64x64; 288

I hope this clears things up
