buggy rotation of non-scalable font

[<pl...@pi...>]

Hi,

I just tried outputting to png terminal and it failed to find a scalable
font. I have not found out why yet, but I don't recall this error last
time I did this a few months back.

gnuplot> load "foo.gnu
Could not find/open font when opening font "arial", using internal
non-scalable font


However, the result of this is text misplacement.

set xtics out nomirror  rotate by -45

Now it seems that 45-rotation is not possible with whatever font it
substituted but what it did output was the tick label going straight
upwards from the origin (close to the tick mark) where the rotated text
would have started.

There seem to be two problems here.

1/ rotate -45 should slope down to the right. Here it IS rotated but +90
, no rotation or -90 would be a better fall-back.

2/ if it does rotate up the origin is totally wrong (ie not recalculated
for the actual rotation) and dumps all over the plot area.


My guess from the behaviour is that the actual rotation is a bug rather
than a fall-back , or at least a buggy fall-back.


This was running std release version 4.2.2
