[squeak-dev] Q: Why are TTCFont Glyphs forms of depth 32?

Jerome Peace
Hi all,


Q: Why are TTCFont Glyphs forms of depth 32?


As a bug tracker I've been looking into a whole slew of font code.
It is  sprawling and confusing (to me).
I can't easily figure if what I am looking at is legit or not.

So first an easy queastion.
Can anybody help with an answer?

Yours in curiosity and service, --Jerome Peace

A 32 bpp form is TSTTCPW if you want an alpha channel. An 8 bpp form  
would suffice, but require more exotic bitblt rules to be interpreted  
as an alpha channel.
