I doubt it would work for FreeType fonts, which hold external handles.
mmmmm but do you want also to serialize external handles ? what are
you going to do with them when you load the objects again to memory ?
That was my point exactly, read Object>storeOn: (which Fonts currently
use), I thought Steph's suggestion was to use that method to serialize
fonts.
However, I think I misunderstood, and Steph meant to write the logic for
storing attributes you'd need to rebuild a Font instance in
store/writeOn: and readFrom: methods. (storeOn: is usually reserved for
writing an executable expression which will yield the instance, so it's
probably a bad idea to use it paired with readFrom:)
Which is an option of course, but the usual convention in image
readFrom: methods seem to be having them instance-side.
That wouldn't make sense if you want to return an already-existing,
closest fitting to the saved attributes, Font instance.
Cheers,
Henry
For StrikeFonts, it may, but even if it did, you'd probably end up
importing a new Font instance (complete with an XX KB bitmap), for
each Morph...
