Subject: questions about combination of rotation and italic

 

 see following code as an example

 

 FT_Matrix    italic_matrix,matrix;

 

 italic_matrix.xx = 0x10000;
 italic_matrix.yx = 0x00000;
 italic_matrix.xy = 0x06000;
 italic_matrix.yy = 0x10000;

 

 if(italic)
 {
  SetRotationMatrix(RotateAngle,&matrix);
  FT_Matrix_Multiply(&italic_matrix,&matrix);
 }

 FT_Set_Transform( face, &matrix, &pen );

 

 

    Just multiply the matrixes do not return a corrcet value in advance!!!!

    If RotateAngle is 45 degree, only 35 degree can be seen on the screen with italic mode.

    How to combined rotation and italic correctly in matrix?
