Hi,

How can I convert this matrix to a one that actually transforms a PageItem in the document ? Seems like PlacedItem's matrix is defined in a very mysterious coordinate system that never been mentioned anywhere in the documentation.

regards

Can you re-phrase your question I don't understand what you want to do here…?

I want to convert the PlacedItem::matrix to a local transformation matrix relative to the artboards coordinate space.

A typical placed item matrix

(a,b,c,d,tx,ty) = 0.8474169969558716 0.5309280157089233 0.5309280157089233 -0.8474169969558716 -2089.5380859375 10003.640625

but the bounds of the item are: 638.2664184570313,-194.9597625732422,783.7483520507813,-345.822021484375

as you can see the translations are extremely bigger than what it sould be, the matrix is obvously not defined at the same space with bounds(which is defined in artboard space).

My aim is to replace a PlacedItem with the original contents from another AI file(like embedding). To do that I need to transform copied elements to the exact same place of the PlacedItem, what I need is the matrix that I can apply to the elements from original file
