Problems with ITextFrame::GetMatrix function

[arenol]

Can anyone explain the values of the matrix returned from the ITextFrame::GetMatrix() function (wrapper for sTextFrame->GetMatrix()).

The a,b, c and d values which represent the rotation (and possibly the shear deformation) are OK,

but I can't relate the tx and ty values to the position of the text object on the artboard.

As a test I tried the following code:

AIErr

CreatePointText( short paintOrder, AIArtHandle prep,

                 AIRealPoint *textPoint, AIArtHandle *newText)

{

     AIError error;

     error = sAITextFrame->NewPointText( paintOrder, prep,

                                         kHorizontalTextOrientation,

                                         textPoint, newText);

     TextFrameRef ateTextRef;

     error = sAITextFrame->GetATETextFrame( *newText, &ateTextRef);

     ATE::ITextFrame ateText( ateTextRef);

     AIRealMatrix matrix = (AIRealMatrix) ateText.GetMatrix();

}

But the tx and ty values returned in matrix are now both 0.  They should equal textPoint.h and textPoint.v, shouldn't they?

It seems that a newly created point text object will  have tx and ty equal to zero.

If I duplate that object by alt-dragging it to another location,  tx and ty will have location relative to the original object.

If I rotate the original object tx and ty will have non-zero values.

I need absolute coordinates...

Looks like you should check out the Hard and Soft coordinates functions.

Tried that now. Didn't make a difference...

Found a workaround.  I need the coordinates of the text anhor for point text and expected that the ITextFrame::GetMatrix method would provide this in the matrix' tx and ty memebers,  It doesn't! I guess it should, so it's a bug.

However, the AITextFrameSuite (not TextFrameSuite , these are two different suites) has a GetPoinTextAnchor function that gets the coordinates.
