Topic: Handling appearance stream without a TM value

We have a number of appearance streams associated with Form buttons. They contain Td commands, negative TFS commands but no Tm commands as well as several draw commands.

Trial and error suggests the font size should be 8 but the commands given are

TFS /font -1.5786
Td 8 7.43
TJ(4)

This gives us the matrix
-1.5786 0 0
0 -1.5786 0
8 7.43 1

for the text

Is there a special way to treat Td if no Tm has been applied?

Regards,

MArk
