Pdf annotations are not being drawn

[migueloliveira-agentifai]

.pdf documents that contain annotations are drawn without them.
https://github.com/barteksc/PdfiumAndroid , in which the library is based, draws the annotations.

Can you provide me with an example PDF?

[migueloliveira-agentifai]

Sorry, I completely forgot to upload it. Here it goes:
pdfsample.pdf
It will be missing "22/12/2023" when rendered with the sample app.

The macOS Preview app renders it as:

The annotations, currently in pdfium are only drawn, perhaps this also allows them to be compiled

Maybe with this commit you could also compile the pdf with foarms. Would be great

From the pdfium code:
// flags - 0 for normal display, or combination of the Page
// Rendering flags defined above. With the FPDF_ANNOT
// flag, it renders all annotations that do not require
// user-interaction, which are all annotations except
// widget and popup annotations.

We or in FPDF_ANNOT if renderAnnot is true on renderPageBitmap, but it still doesn't render that page correctly. Happen to know what kind of annotation it is?

@johngray1965 unfortunately I don't, as I don't have access to how the pdf is generated. But I would say it is an interactive form, which is a type of widget.

It is related to FPDF_FFLDraw not called for new version of Pdfium render annotation and signature.

I made some modifications to the code in PdfiumAndroid
code ref to sample of pdfium

@marain87 would you be able to add other functions such as search and more from these two repositories?

https://github.com/Lesmm/AndroidPdfViewer/tree/develop ( in this branch search and selection works)

https://github.com/TEA-ebook/AndroidPdfViewer (search, selection and highlighting should work here)

[johngray1965]

@odmfl those projejcts are viewers. This projects wraps the native pdfium api to provide the APIs to an Android app. We project isn't a viewer. You are talking about viewer functionality.
