Is there a way to drop images transformation for specific xrefs ?

[PasaOpasen]

My goal is to deskew all images on the page. But I found that some of them are already rotated well and are just inserted into document with some degree.

I found that this information is available as transform:

>>> doc[0].get_image_info(xrefs=True)

[{'number': 0,
  'bbox': (0.0, -6.103515625e-05, 594.9500122070312, 841.8999633789062),
  'transform': (594.9500122070312,
   0.0,
   -0.0,
   841.9000244140625,
   0.0,
   -6.103515625e-05),

is there a way to change transform of 58 image?

No, we have no way to do that.

thank u!

@JorjMcKie seems like inserting this image without rotation works!

>>> r = doc[0].get_image_info(xrefs=True)
>>> rect = fitz.Rect(*r[1]['bbox'])
>>> doc[0].insert_image(rect, xref=58)

this will create new object with same xref but result document looks exactly how i wanted

is there some disadvantages ?
