I wasnt sure what to call these images - they are completely black/white - NOT greyscale; 1bit TIFF files.
The DOpus 10 viewer seems to just show a thumbnail. Other viewers including windows default viewer are able to display these images correctly.
I attach three files:
Note in the preview I can only see two files - I cant see the sample file- it looks like the forum has the same problem as the viewer
I'll try just leaving the sample as an attachment
~ as it looks in windows default viewer @ 100%
~ as it looks in DOpus viewer (says 800% but that's 800% of the thumbnail I presume)
~ a cropped version of the file viewed
