Minor edit majorly changing font

[tevert]

I made a very minor edit to an OpenType font: I added a new Stylistic Set. And Exported the font back to an .OTF file.

However it's rendering significantly differently, and not as well. Left is original, right is after edit in FontCreator Pro 9.0 (Build 1916)

Is there some setting I can do to leave the font in tact with just the new stylistic set added?

On the export I did leave hinting set to Keep Original. The new font file is 94k. The original was 62k.

Thanks,

Tony

Can you please send both original and modified version to us through customer support?

[Erwin Denissen]

Thank you for sending the font files.

The original font contains CFF (Postscript) based outlines, which are converted to TrueType based outlines on opening with FontCreator. Then on export they are converted back into CFF but have lost the original hinting.

You could try to see if exporting as TrueType works, with Auto Hinting, but it will never be 10% equal to the original due to differences in hinting and conversion (rounding).

Aww that's really too bad. It would be nice if metadata like this could be added without changing the font!

It would also be nice if on any edit the original CCF outlines and hinting could be preserved as far as possible.

I can't agree more, so we are thinking about a way to find a solution.

Does version 10 address this?!

[Erwin Denissen]

No, this is a complex feature request that we intend to include in version 11.
