How to replace images if there is changes in the original one, and more than 1 reference in PDF doc?

To do so, traverse the page’s content as in the ElementEdit sample (https://www.pdftron.com/pdfnet/samplecode.html#ElementEdit). When you
encounter the image in question (you can obtain the SDF object with Element.GetXObject()), you can create a new image with ElementBuilder
(see https://www.pdftron.com/pdfnet/samplecode.html#AddImage) and add it in with ElementWriter.

Ok, but, isn’t it so that if I create new image, I should provide information regarding howto put the new image, because it is
possible that the original image can be eg partly behind another image, if there is say some artistic reasons for image layouts?
Possibly will never encounter that, but still… I mean that orig image rect info is not enough, I should provide info also how to
set the new image regarding other elements inside that specific page?
