Hi All:
I am having a similar problem on stand alone 2.8.2 on PC with HDMI
screen. I set the screen canvas to 8 inch by 10 inch and made a screen
dump. The result was an image that was 4 by 6 inch instead of 8 x 10.
However the text on this image was the same size as on the screen. The
image declared itself to be 96 dots per inch but my HDMI screen is
only 70 DPI. If I enlarge the image to 8 x 10, the text is 133%
of screen size text, but the map is at the correct scale. It seems
like QGIS is scaling the text to 96 DPI and the graphics to Screen
resolution (70 DPI in this case).
Thanks
Tom

I am using QGIS 2.81 under Ubuntu to prepare some maps, and am
experiencing difficulties with text font sizes between the project
window and the print composer. I encounter two problems:
1) When I set the font size for a label in the project (e.g. 10
point) the text appears overly small. When I use this layer in the
print composer the font appears oversized. To have the label
appear at an appropriate size in the print composer I have to
reduce the font size in the project window (e.g. to 7 point). It
then appears to have a size of c. 10 point in the print composer
window. This problem, combined with the fact that positioning a
label in the project window so that it appears correct in the
print composer requires much to and fro between the windows - and
that is just for one label - makes use of labelling problematic. I
have to tweak the position of each label individually in the
project window, and it is largely guesswork.
2) If I add a text label (e.g. 10 point) directly in the print
composer window the text is oversized and to obtain c. 10 point I
have to set a font size of c. 7 point. This is less of a problem
than problem (1) but nevertheless perplexing. For my maps I am
tending to add all labels using this method, rather than using
labels from the layers, because of problem (1). For complex maps,
however, this quickly becomes complicated for a variety for reasons.
I am relatively new to QGIS so perhaps I am missing something /
doing something wrong. Could anybody with more experience kindly
advise how these matters can be resolved?
With grateful thanks, Martino
