Hi Michael,
you're right, the default y position is not referred to the baseline but
to the upper left corner of the text. I initially referred it to the
baseline but that is not the default used by the current drawtext
filter, so I thought it would be better to keep compatibility with the
current filter.
I'm open to both solutions: if I refer the y parameter to the text
baseline, than the current default can be achieved using the expression:
y = <value> + top_a
being "top_a" a new variable I'm introducing with the meaning "maximum
ascent of the first line".
If I keep the current default, than what you're asking can be obtained
using:
y = <value> - top_a
I'm new to the ffmpeg devs community so I'm not sure whether it is
preferred to keep backward compatibility or to change the behavior in
the name of a better interface.
What do you think?
Thanks
Francesco

Hi Francesco,
in my opinion the line spacing looks good. But there is still the
problem that the y position of the baseline depends on the height of
the characters in the first line. You see that when you switch between
your pictures line_height_net_arial.png and line_height_new_arial2.png.
I know that it can be corrected by specifying the y position as
"40-ascent" for example. Is it possible to make that the default?
Michael
