Hi Enrico,
I can't tell why this expression fails, but there is a more elegant way
to distinguish between even and odd numbers. The modulus operator (%).
CASE WHEN @atlas_featurenumber % 2 = 0 THEN --these are the even pages
210 - @value
ELSE --these are the odd pages
@value
END
The
Is there a way to get the current item value that is being modified by
expressions.
I would like to reformat my print composer atlas for two sided printing
referencing to @value variable without success:
CASE
WHEN floor( @atlas_featureid/2 )*2 = @atlas_featureid THEN 210 - @value
ELSE @value
