Thank you for pointing out "shave bytes".
In fact, this time it is "inflated bytes". Comparing the pdf file generated
directly and the one transferred through SMTP using "content-transfer-encoding:
quoted-printable", all 0A is inflated to 0D 0A and all 0D is also inflated to
0D 0A. There is no other difference. Just this minor inflation blows up acrobat
reader and it shows up as blank pdf. (There is no such inflation if base64 is
used as content-transfer-encoding during SMTP transfer.)
So the pdf generated by iText contains either 0A or 0D but not 0D 0A together.
Is this by design? Or is it configurable?
P.S.: all test is on Windows platform.
