SVGX is just an vector file, lacking of any other precious information for UVtools to work.
UVtools works with images and those require Resolution size to be known, without it UVtools can't recreate the image from the svgx file, and is not possible to just guess it.

So this is not a bug, but rather a incompability by flashforge and the way they built the format.
The only solution to use UVtools with SVGX is using other slicer that is able to convert or output svgx with my required meta data inserted.

• PrusaSlicer (With my printer profiles)

Is the only slicer able to slice and export svgx (after open sl1 on UVtools) with inserted metadata for UVtools to work (I altered the svgx format with the missing information that is required)

But you can use other slicer as well, like Chitubox or Lychee, Tango, which i highly recommend over flashforge slicer, create a printer with same dimentions and properties, export to a known format, like zip, load into UVtools, do your stuff and convert to SVGX.

Also SVGX files created by UVtools also insert the missing information, so you can load it back if required

Hi, Tiago. Thanks for your quick response. I have tried both with Tango and Prusaslicer to create svgx but it did not work. Could you please advise where to insert the resolution and display size information in Flashforge's svgx file? Resolution : 1920*1080 pixels Display size : 120*67.5*150 mm (4.7*2.7*5.9 INCHES) I have attached a 20mm box sliced svgx file. Thank you very much. Warm regards, David Lee

Prusaslicer is unable to creat svgx, you need to export sl1 and open in uvtools with my printer profiles and it will turn into .svgx automaticly: https://github.com/sn4k3/UVtools/wiki/Setup-PrusaSlicer

Tango can do the same thing, you export to vdt and then go to uvtools and convert to SVGX.
Any of these are better than insert the bytes yourself

Could you please advise where to insert the resolution and display size information in Flashforge's svgx file?

You will need an hex editor able to paste and insert text in right position, heres where (The orange text and replace by your values):

Yes, on UVtools you can go to Help menu and click either sponsor or donate.
Official sponsor channel it's the github itself: https://github.com/sponsors/sn4k3 (Prefered)

@mderosa89 Wrong resolution defined on slicer. Check your settings. Error is clear.
