Good afternoon,
 I hope you can help me to resolv my problem.
In one of my programs, I have to transform a tiff file into a bitmap =
object. The transformation requires the creation of an intermediate =
object, a bitmapdata object.
This creation is done pixel by pixel : it means that for every pixel =
from the tiff file, we create a structure of 4 Bytes to store pixel =
informations.
1 How can I proceed in the aim to reduce the strucutre into one byte ?
2 How can I read a tiff file line by line of pixels or bloc by bloc of =
pixels ?( how using scanline)
Thank you
have a nice day
