query regarding oddbtext alignment and position

query regarding oddbtext alignment and position
hi all,
i have a query regarding setting the alignment option for oddbtext entity.
i have done this by the following piece of code..
and i have not used any fonts.
pblock = m_pdb->getmodelspaceid().safeopenobject(oddb::kforwrite) ;
ptext = oddbtext::createobject();
ptext->setposition(odgepoint3d(ptx, pty, 0));
ptext->recordgraphicsmodified(false);
ptext->setheight(10);
ptext->setwidthfactor(3);
ptext->settextstyle(oddbsymutil::gettextstyleid("standar d", theapp.m_pdb));
ptext->settextstring("hello world");
ptext->setrotation(0);
ptext->sethorizontalmode(oddb::ktextright);
ptext->setverticalmode(oddb::ktextvertmid);
pblock->appendoddbentity(ptext);
i hope i'm not using any fonts. but the position of the text seems to be invalid.
am i doing the right way. i'm not using any fonts, so do i need to use the .shx file..?
if so, i don't have autocad installed. so how can i create a .shx file..?
is it a must that if i'm using a oddbtext entity, then i must use a .shx file. for proper alignment..?
tia

if the horizontalmode is not ktextleft you have to set the alignment point.
try this:
code]
ptext->setalignmentpoint(odgepoint3d(ptx, pty, 0));
[/code]

hi froggy,
thank you for your response.
can i know more detail about this. i need to implement all the possible combnations. top left, top center, top right, bottom left, bottom center, bottom right, middle left, middle center, and middle right.

if text alignment is left-baseline use setposition(). in other cases use setalignmentpoint(). dd will calculate other point (position or alignment). to perform the calculation dd needs access to .shx file.
if required .shx file is not available you can set both position and alignment point yourself and call recordgraphicsmodified(false) to prevent recalculation. but recordgraphicmodified() will take effect only if it's called after all properties/coordinates are set because any oddbtext modification turns the graphicsmodified flag on.

hi sergey,
as you told i have modified my code. but for all the positions, its placing the text ane bottom corner of the drawing...
please help...
code below..
pblock = m_pdb->getmodelspaceid().safeopenobject(oddb::kforwrite) ;
ptext = oddbtext::createobject();
ptext->setheight(height);
ptext->setwidthfactor(3);
ptext->settextstyle(oddbsymutil::gettextstyleid(strstyle , m_pdb));
ptext->settextstring(strtext);
ptext->setrotation(0);
ptext->getboundingpoints(temparray);
nstyle = getjustificationindex(just);
switch (nstyle)
{
case 1: // top left
ptext->setalignmentpoint(temparray[0].x, temparray[0].y);
ptext->sethorizontalmode(oddb::ktextleft);
ptext->setverticalmode(oddb::ktexttop);
break;
case 2: // top center
ptext->setalignmentpoint((temparray[0].x + temparray[1].x)/2 , temparray[0].y);
ptext->sethorizontalmode(oddb::ktextcenter);
ptext->setverticalmode(oddb::ktexttop);
break;
case 3: // top right
ptext->setalignmentpoint(temparray[1].x, temparray[0].y);
ptext->sethorizontalmode(oddb::ktextright);
ptext->setverticalmode(oddb::ktexttop);
break;
case 4: // middle left
ptext->setalignmentpoint(temparray[0].x, (temparray[1].y + temparray[2].y)/2);
ptext->sethorizontalmode(oddb::ktextleft);
ptext->setverticalmode(oddb::ktextvertmid);
break;
case 5: // middle center
ptext->setalignmentpoint((temparray[0].x + temparray[1].x)/2 , (temparray[1].y + temparray[1].y)/2);
ptext->sethorizontalmode(oddb::ktextcenter);
ptext->setverticalmode(oddb::ktextvertmid);
break;
case 6: // middle right
ptext->setalignmentpoint(temparray[1].x, (temparray[1].y + temparray[1].y)/2);
ptext->sethorizontalmode(oddb::ktextright);
ptext->setverticalmode(oddb::ktextvertmid);
break;
case 7: //bottom left
ptext->setposition(temparray[2].x, temparray[2].y);
ptext->sethorizontalmode(oddb::ktextleft);
ptext->setverticalmode(oddb::ktextbottom);
break;
case 8: //bottom center

if you use recordgraphicsmodified(false) to prevent dd recalculation of second point you need to set both position and alignment points.

hi sergey,
even if i don't use the recordgraphicsmodified(false) option, the same result is performed.
am i creating the right way ..?

you call getboundingpoints() to fill temparray.
at this moment text position was not set so it has (0,0,0) value. temparray is filled with values around (0,0,0)
when you use them to set position or alignment.
surely all texts are near (0,0,0)
btw getboundingpoints() needs .shx files to calculate string dimensions properly. if fonts are not available default font will be used and results will be incorrect.

hi sergey,
if i am using the font standard, then is it necessary that it needs the .shx file for the getboundingpoints() function..?

standard is not font it's text style. any text style can have any font (shx or ttf)
dd has a built-in font similar to simplex.shx which is used if no other fonts are available.

hi sergey,
so is there any default font(s) available, or is there any limited fonts available, which can be used, such that there may be no need of any external files (*.shx)..?

dd has single built-in font similar to simplex.shx.
on windows platforms ttf fonts installed in your system are also available.
