Rotate +90° makes LZW-gray from G4-BW

I have TIF, BW, Group 4. I try to rotate them 90°, here is my XBS:
Code: Select all
<?xml version="1.0" encoding="UTF-8" ?>
- <XnView_script version="1.0" name="TIFF_rot_90">
<Rotate angle="90" smooth="false" color="#ffffff" />
- <Output folder="" filename="{Filename}_90_rot" case="0" format="TIFF">
<Options overwrite="0" orgDate="false" keepMeta="false" keepICC="false" keepFolder="false" delOrg="false" multipage="false" allPages="true" openExplorer="false" />
<TIFF compress="2" compressBW="6" oneStrip="false" />
</Output>
</XnView_script>
Is it rotated fine, but the resulting files are "Gray / LZW" - no matter if I select "Output = TIF" or "Output = same as input".
When I set "change color to BW" then it is OK
Code: Select all
<Change_color_depth method="0" dither="5" ncompo="-1" alpha="255"/>
Bug or feature?

FYI: There's a similar discussion about how
rotation changes the bit depth from 1bit to 8bit in XnView v1.9.

Thanks. The result is:
Option "Smooth / Antialiasing must be selected.
Right?

This works in XnView v1.9, but not in XnConvert v1.1

For me it works fine.
Input: TIF, BW, Group 4
Output without "Smooth": TIF LZW, Gray
Output with "Smooth": TIF G4 BW

It's the inverse
and must not smooth if -90/90°

Input: TIF, BW, Group 4
Output without "Smooth": TIF BW
Output with "Smooth", rotate -90,90,180: TIF BW
Output with "Smooth", rotate other angle: TIF Grey

I tested it with TIF G4,
- set only "Rotation +90°" and
- did not set color or Smooth or something else
- and converted get rotated G4 files.
Seem to work fine.
