Text size in saved document changes on other laptop

[KEN1968]

When I create a PhotoFilter document on a laptop with an HD screen (1920x1080) and open the same document on a laptop with a 4K screen (with a scaled-up screen resolution), the text size changes, becoming smaller or larger, but other parts of the document remain the same size. Does anyone have any idea why this is happening?

Text size is not in pixel but in pixel per inch. When the resolution change, the font size in pixel change. If you want a fixed size you can convert the text to bitmap

Thanks Antonio for your quick response.

I already save everything I create in Photofiltre as a JPG, for example. I understand that in that format, the text size doesn't change on my other laptop.

But does this mean that when I edit a file in Photofiltre on my new laptop, I'll always have this difference in text size?

if you change a text layer with a new resolution screen, the size wll change too, you must adjust it manually (not auto)

Thanks for your reply Antonio, I now know a bit more about the program, which I think is fantastic.
