Thank you Bob for the fast answer. I appreciate it.

You did not say what format the data accessed via imagen->data[] is.

I am sorry it is unsigned char ** data.

The data needs to be packed the same as TIFF, with each 8-bit byte representing 8 pixels.

How can I do that, please? could you give me a sign?

thank you in advance
