INK Picture Control

Hello,

We are using PB 12.5 Build 3072.

We have problems to save a ink-Picture Control in a compression format ("Group 4 Fax Encoding").

It is not possible to save the picture in a TIFF format.

After re-opening a modified picture in a ink-Picture Control, there

is only a part of the picture visible.

How can we save a picture in TIFF Format (300dpi / Kompression Group 4 Fax Encoding )?

TIA

Michael
