🚀 go-pugleaf

I have a couple of InDesign plug-ins which I am moving from CS3 to CS4. Part of the functionality is to gather information, including position, for images in the document.

I am having, expected, problems with this functionality because of the new spread view rotation and the previous reliance on Pasteboard coordinates. In many places I am getting the bounding box of page items using code similar to:

InterfacePtr<IGeometry> iImageGeometry(iImageHierarchy, IID_IGEOMETRY);
PMRect lImageBBox = iImageGeometry->GetPathBoundingBox(::InnerToPasteboardMatrix(iImageGeometry));

and in certain cases clipping the bounding box to the page bounding box (also in Pasteboard coordinates).

While the Porting Guide discusses the new Transform::SpreadCoordinates() it doesn't really explain how to use that to transform from Pasteboard coordinates into Spread coordinates. I also don't understand why there is not a ::InnerToSpreadMatrix utility method in TransformUtils.h.

My current thinking about this is to keep everything in Pasteboard coordinates and then doing a final tranform into Spread coordinates. Does this make sense?

Thanks for any help,
Nick
