This is a good idea !
I just try it but damn it, when I change the angle
of the text using Alter Object Geography, I discovered that the MBR of the text
does not change !
Stuck again.
Thanks again but we need to think more about this
one !

Hi Dany
have you tryed to Alter the angle off the
text to 0 before you get the MBR
Alter Object MyTextVar Geography,
obj_geo_textangle, 0

NB remember that the height of the text normaly is just 60% of
the MBR
height

Vedr�rende: MI MapInfo Fonts -- A Savage
Journey into Pointless
Pointsizes - REVISITED
Hello all.
I am (too !)
trying to read the size of text objects in a MapInfo mapper
window with
difficulties.
Following Bill Thoen's approach here's what I am
doing:
First I callObjectGeography () to retrieve the minimum
bounding
rectangle (MBR) of the text object.
I then take the vertical
distance between the min-Y and max-Y using the
distance () function
in
inches, and divide by the map scale found in
MapperInfo
(FrontWindow(), MAPPER_INFO_SCALE) (after setting distance units
to
inches).
I get some sort of approximate text size in inches which I
then multiply by
72 to get points.
Actually, this is not working two
badly, since I am more looking for
consistency over exact sizes.
As
expected, trouble begins when you try reading text with an
Angle<>0.
Has anyone come-up with a method that would give an
approximation of the
text size provided you have the MBR and angle (and
text string lenght if
needed) ? I have tryed quickly with Trig functions
but could not figure it
out.
Thanks in advance for anybody helping
chasing that goose !
I will sum.
