Ah, okay. I was just encountering these kinds of overlapping comments

There are probably also incompatibilities in the patches.  There
definitely are size incompatibilities between the new font Pd-
extended and other pd versions.

So now there *are* size incompatibilities with Miller's Pd? I'm just
asking to be prepared, I don't run the Pd from pd-extended, I prefer a
plain MSP-Pd in the latest version.

There are incompatibilities between  different versions of Pd (0.38,
0.39, 0.40), and each of those  versions different platforms
(Windows, GNU/Linux and Mac OS X).  This  version is the same size
to the pixel on each platform.  There is, of  course, no way that
the new sizes could be compatible with all of  variations.  But I
hope you'll agree that this is a better situation.

Of course having Pd look the same on all platforms is a good goal, and
Miller also supported this in the past. I'm not against solving this
at all.  But of course incompatibilities should be kept to a minimum,
I hope you'll agree with that. (Besides the OS-issues, no versions of
MSP-Pd that I've used, had size-incompatibilities when using the same
font.)

I might have been wrong about the version-to-version incompatibilities. I attached a patch that has the size differences that I have measured. Please fill in anything that you might have measured.

Attachment: courier10.pd
Description: Binary data


One thing that I did forget to mention is that the relationship between the font sizes between the iemguis and the object boxes is different on each platform. That is also fixed now, (i.e. 12 points is now the same size in iemguis/boxes on all platforms) That will of course, break the layout of a lot of patches.

I'm just a bit worrind: Now that you've released new fonts into the
(pd-extended) wild, there's an additional, new variable to consider
with regard to compatibility when going further with font
enhancements.

The goal is to fix this problem with the least pain possible. That said, there will undoubtedly be some pain because the current situation is less than good.
