Hello all,

iam still a newbie in here.
My projekt is going to become finished - sooner or later...

I opend a TIFF (Fax G4/G3) with the "ReadTiffIntoBitmap" thing.
then i work with the bitmap, rotate it as i like,
strip lines as i like and all the stuff i need. 
seems to work fine for me.
but iam still not able to safe the file back into the 
G4/3 format.

i found a lot of Info at

# Basic File Handling
# Scanline-based Image I/O
# Strip-oriented Image I/O
# Tile-oriented Image I/O 

and so on.. but all stuff is in C-code - i like to see
a delphi example to safe a file please.
And i did not find any usefull information how2 safe a file
(TiffOpen with "W" ??? )

Do i need to grab me the from the tiff - 
"TIFFTAG_COMPRESSION = 259;  { data compression technique }"
so i can use it to save the file later back into it?

Again - iam a newbie - to tiff and to delphi.
I like to learn a lot - so iam sorry for this newbie stuff in here.
But i did not found a forum or so .... 
( and execuse the bad english as well - thank thee ) :-)
Mit freundlichen Gruessen
