Element.GetBBox() and rotated pages

[Support]

Q:

I have pages with a rotation of 90 but the coordinates of the GetBBox() function on a line or word object are not rotated.

The documentation of the GetBBox() function says:

     The bounding box already accounts for the effects of current transformation matrix (CTM), text matrix, font size,

      and other properties in the graphics state.

Anything special I need to do to get the correct x, y, x2, y2 ? 

-------

A:

GetBBox() does not include the effect of Rotate and CropBox attributes in page dictionary.

To apply the effect of page rotation and crop box transform GetBBox() rect with GetDefaultMatrix().

For example:

 

Rect bbox = …

Matrix2D mtx = page.GetDefaultMatrix();

mtx.Mult(ref bbox.x1, ref bbox.x1);

mtx.Mult(ref bbox.x2, ref bbox.x2);
