High quality zoom bug for 1-bit images
Posted: Thu Sep 26, 2013 6:03 pm
The bug can be illustrated using the following file:
Open the image in XnView Classic,
View with Tools > Options... View > View tab -- High quality zoom unselected, then select and note the improvement in the image quality;
Open the image in XnViewMP,
View with Tools > Settings View > View tab -- High zoom quality unselected, then select and note there is no improvement in the image quality.
Finally, compare the image in XnViewMP with that in XnView -- both now with High quality zoom selected.
The bug seems to be specific to 1-bit images (tested TIFF and PNG).
