Control which PDF objects are rendered (text, images, etc.) and how they are drawn

[G705-Ghilan]

Hi, first of all, thank you for the great work on the pdfrx library
it’s amazing PDF viewer

We’re developing an app that uses pdfrx to display PDF pages, and we’ve reached a point where we need more control over what PDF objects are rendered and how they are drawn.

Specifically, we’re looking for answers to the following use cases:

1. Selective rendering of PDF objects
   For example, is it possible to disable rendering of text objects entirely, while still rendering images and other PDF elements? In other words, we’d like to show the visual content (images, shapes, etc.) but hide all text.

2. Custom text rendering / interactivity
   Another use case is rendering PDF text as Flutter widgets instead of being flattened into the rendered page image. This will enable more interactivity with text

Are these kinds of customizations supported by pdfrx today?
If not, are they theoretically possible with the current architecture ?

Any guidance, limitations, or recommended approaches would be greatly appreciated

Thanks again for your work on pdfrx :)

Currently, pdfrx does not have such features so far. But we're considering such kind of editing features on pdfrx 3.0.

And, basically, the current pdfrx structure can handle page editing events correctly though it does not provide page editing features nor export PDFium's document/page handles directly.

The easiest way to support such page editing feature is to export PDFium's document/page handle by some pdfrx API though it requires user to call PDFium's functions directly (it's not easy actually).

Is there a timeline for this feature? I'm looking at building something that would require something like this. Thanks for all the hard work you've put into this already!
