【转帖】setverticalmode90 Not Modifying Alignmentpoin
 

setverticalmode() not modifying alignmentpoint
setverticalmode() not modifying alignmentpoint
i have a text object in dd2.2 database which has a verticalmode == oddb::ktextbase.
i modify the vertical position with :
ptext->setverticalmode(oddb::ktextbottom);
ptext->alignmentpoint() is not recalculated. it returns the same value before and after the setverticalmode().
as ptext does not support recomputedimblock() how to get the new correct alignmentpoint() ?
thanks
some more infos:
i now use
ptext->setverticalmode(oddb::ktextbottom);
ptext->adjustalignment(ptext->database());
the position changes, not the alignement.. ok ! but dd does not recalcuate the coords. properly:
position before adjustment: -11191.6981, 22125.4029, 0.0000
alignement before adjustment 0.0000, 0.0000, 0.0000
position after adjustment: -0.011080, 3.7143,0.0000fff"> <-- this is wrong . autocad gives 11191.7093, 22129.157, 0,0000
alignement after adjustment 0.0000, 0.0000,0.0000
i suspect this is a bug ??

if vertical or horizontal alignment is changed the alignment point is not recalculated. it stays in place. position (left-baseline) point is recalculated.
the recalculation is done at the moment the text entitity is closed. to force recalculation without closing the entity call adjustalignment().

as mentioned in the second post, this is what i do, but the calculated coordinates for the alignement point are wrong :
position after adjustment: -0.011080, 3.7143,0.0000 fff"><-- this is wrong . autocad gives 11191.7093, 22129.157, 0,0000
when a text is ( verticalmode = txtbase and horizontalmode= txtleft ), the alignement point is (0,0,0) in autocad. (this is the only case !!)
changing the verticalmode from txtbase to txtbottom, dd returns the deltas instead of properly recomputing the point ! ( the deltas are probably added to the null point which is not a position value in this special case ! )
damned !

dd implementation is arx like. in objectarx the behavior is the same. if you change vertical alignment via autocad's gui in case if alignment was left/baseline position value is assigned to alignment.
but this is done not inside setverticalalignment() function.
