text output
i'm trying to convert some text into a dwg file.
the information i have is a logfont, a bounding box before transformation, and the transformation.
i can output text be specifying the height to be the height of the bounding box.
i.e.
oddbtextptr ptext = oddbtext::createobject();
ptext->setheight(bbox.height());
this works fine unless the text contains letters that are higher and lower then the letter 'a'.
e.g. "bottom" outputs fine as does "paper" but "diaper" is incorrect.
the symptoms are that "diaper" is approx 1/3 larger than the bounding box.
is setting the height for text this way correct? if so why the problem with "dp"? if not, how should i do it?
i'm using dd 1.12.04
in autocad "text height" is treated as height of "a" symbol not the height of bounding box. coefficient to convert between these two heights depends on font metrics - it is different for different fonts.
