Issue with text rotation

[arunsrinivaasrs]

I have issues with text when the page is rotated. Exported as Landscape pdf.

Below is the code that i apply for other elements like Line, Rect and it works fine. 

currPageRotation  = page.GetRotation();

pdftron::Common::Matrix2D rotMtx(currPageRotation * DEG2RAD); //Note that i have a rotation angle of 270

For elements i multiply page rotation matrix with ctm,

pdftron::Common::Matrix2D ctm = path.GetCTM();

ctm *= pdftron::Common::Matrix2D::RotationMatrix( currPageRotation * DEG2RAD ); 

After multiplying all points with ctm,  i see that the rotation is fine and i see the elements in right place. 

But when i apply the rotation matrix to text it does not rotate properly. Below is the code.

               pdftron::Common::Matrix2D text_mtx = element.GetTextMatrix();

               text_mtx *= rotMtx;                

               pdftron::Common::Matrix2D ctm = element.GetCTM();

               ctm *= rotMtx;

               pdftron::Common::Matrix2D mtx = ctm * text_mtx;

I then multiply the resultant mtx with the character positioning information.

                       for (pdftron::PDF::CharIterator itr = element.GetCharIterator(); itr.HasNext(); itr.Next()) 

                       {

                             char_code = itr.Current().char_code;

                            charBuffer += string(1,char_code);

                            insertionPointX = itr.Current().x;

                            insertionPointY = itr.Current().y;

                            mtx.Mult(insertionPointX, insertionPointY);

                       }

It appears you are missing a call to Element.SetTextMatrix:
