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:
CreatePointText( short paintOrder, AIArtHandle prep,
AIRealPoint *textPoint, AIArtHandle *newText)
error = sAITextFrame->NewPointText( paintOrder, prep,
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...
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.
