Effects og shape exported at wrong resolution when changing DPI

EDIT: Solved, not a problem in Designer - but in the image viewer.

 

Hi Serif

I am working on a drawing in A3 size in AD 1.7.481.

  • Originally the document was set to 300 DPI and it exported fine.
  • Now if I change the document to 600 DPI or simply double the export size in pixels quite a few edges are exported with horrible jagged edges.
  • Changing resample method doesn't make any difference.

Cut out from the drawing. It is a small door number. All is vector shapes with applied effects.

image.png.724753de4d8699bc49128ab1956d711b.png 600 DPI, , TIFF 16 bit RGB

It looks like the effects are rendered in 300 DPI and scaled up? Why is it not rendered smoothly? 19 is a vector shape!

Thx

Changing the DPI and exporting is all that is needed to reproduce.

Hi Jowday,

The attached file is already 600DPI, however rescaling down to 300, saving, closing, opening back up and then rescaling to 600 still allows the export to go out without a problem!

Could you attach the resulting TIFF file that your screenshot is showing please? I've attached a copy of the TIFF file I got from the above operation. It gives me the same result as  v_kyr

When I open and export this afdesign file (Windows 10 pro) as is this is the TIFF I get.

TIFF, PNG, same result

Same result from two machines.

I chose “objects will rescale” when I changed DPI btw.

Attached a version of the file before DPI was changed.

Sounds like a Windows only issue.

BTW just expoeting to 10000 pixels in height triggers the problem no matter the DPI setting.

How are you viewing the exported TIFF? I noticed the Windows Photo Viewer gives the bad filtering you seem to get but when zoomed right in is fine. If I then open it in Affinity, it again is fine.

Thanks! I use FastPictureViewer Professional and it shows it with jagged edges even at 100% - I simply didnt suspect it could render an image wrong at 100% ... confused.

I now opened the same files in Photoshop 2020, and Indeed the file looks great and as expected.

Note: disabling GPU support in FastPictureViewer Professional improved rendering a bit.

Thank you for your time!
