thank you for answering ...
I suppose this is not the wisest way ..... but only to understand the matter
....
if I understood you, my problem was 1 0 0 1 10.1406027 4.7716582 cm(*)
wasn't the position of the image, but it was a modification over the present
CTM.
So to extract the position of that image I had to multiply this one(*) with
the present CTM in the graphics state (graphics state parameter CTM of
graphic state -PdfReference 8.4 Graphics state 8.4.1 General)? Or otherwise,
this operation has no sense because the present CTM parameter isn't
one representing
all previously existing transformations (in that case I had to do manually
from all or only some of the previous transformations?)?
And could it be possible to retrieve this present CTM from the graphics
state stack of the pdf I am creating from using itext ?
Sorry for my insistence but I'd want to understand all this ...
Thanks
