Hi,
first of all great library with some very cool tools/examples.
What I'm trying to do: Take an existing pdf with image over text and
replace the images with smaller black-and-white versions.
What I have: I have the pdf with the text, I have the smaller (filesize)
versions of the images.
To get there I figure there are two ways:
1. Load the pdf, delete all the image-objects, add the new Images.
2. Create with the images a new pdf and copy the underlying text from
the pdf into the new one.
ad 1.) is it possible to "replace" an image with a new one? As far as I
saw, I can only delete the reference to an object, but not the object
itself, which would make the filesize even larger
ad2.) is there a simple way, of copying text objects from one page to
another? I tried starting with the text-extract example, but didn't get
anywhere so far. Redrawing a text that already exists with the correct
font and all seems so redundant.
If anyone has an idea, or could shove me into the right direction it'd
be greatly appreciated.
all the best,
Christof
