Saving page using the extracted dictionary

[SrijithBalachander]

Hi, I just started exploring PyMuPDF for my use case and have been struggling to do one simple thing. I extracted a page of a pdf as a dictionary using get_text("dict") where I perform a few font-size changes. I would like to save these changes back into the page or create a new page and enter text using the dictionary. How can I go about doing this?
Thank you!

Iterate over the dictionary - there are 3 hierarchy levels: blocks, lines and spans.
For every span perform a page.insert_text(), taking the following argument values:

• insertion point: span["origin"]
• text: span["text"]
• fontsize: span["size"]
• fontname is a trickier thing:
  • if you can use one of the Base-14 fonts, Times-Roman, Helvetica, Courier. Watch for choosing the right font weight / style by inspecting the span["flags"] value.
  • re-using existing fonts is difficult if writing to a new file - save this for a time when you have more experience.
  • using file-based new fonts is also not straightforward: you must first insert the font to the page, assign a fontname to it, e.g. "F1", then use fontname="F1" in the insert_text instruction.

Please also note that there is a font replacement utility here which does a very similar thing. Maybe you can draught insight from it.
