How to identify the correct position of shapes in Visio

[Kumar]

I am developing a program in Visual C++ to read shapes in Visio drawing XML
document (.vdx) and draw in MFC dialog . I need to know the actual
postion(x,y) of shapes in XML in order to draw the shapes in MFC dialog .

I read the position by reading the <PinX> of <XForm> tag but I did not get
the shapes in actual position. Specifically I think the position of the
lines are not correct.

Can you please help me in this regard.

Hi Kumar,

The location of a shape is a combination of it's Pin, it's LocPin, and it's
Angle and Flip as well. Also, geometry can be outside of the shape's
width/height box, and geometry is specified in the local coordinates of the
shape.

The LocPin specifies where on the shape the Pin hits. For instance, a LocPin
at (0, 0) is in the lower-left corner. The default Pin is at (Width*0.5,
Height*0.5) You can see that this in the local cooardinates of the page.

The Pin is where the shape is located on the page.

Hi Chris,

Thank you very much for quick reply.

Actually I was able to locate the position of shapes other than lines as
you mentioned . I could not get correct position of lines as in the Visio
document.

For line shapes I used the <PinX> in <XForm> as other shapes but the lines
are little deviated from actual position ( not connected to other shapes) in
MFC dialog


Regards,
Kumar

Oh, I get it. For Lines, you have BeginX/Y and EndX/Y

Hi ,

Thank you.

I tried as you said but I still could not get the correct position of lines .

I am sorry for not responding quickly .

I need more favor from you . Is it possible to forward my Visual C++ project
, which I developed to you (to your hotmail )for identifying the mistake I
made.

Regards,
kumar.

Keep in mind that shapes can be inside groups. In that situation there are
multiple transforms that must be read and applied to get the actual page
coordinates.
