Roman page in pdf

I have a question, into the pdf we insert pages containing Roman and Arabic numerals, typically roman numbers are at the beginning of the file, programs such as Adobe Acrobat or ADE recognize these different types of page numbers, would it also be possible with our library? See the example below.
because we noticed that pdf tron ​​automatically numbers the pages.
There is a solution?

Many thanks!
Giuseppe

Hey there!

PDFTron has some special logic inside the rendering engine that does this, and unfortunately we do not have that logic inside PDF.js Express which means this is not something we can support at the time.

Thanks,

Does we have the function to read the Page Label in Roman/Arabic in our SDK? We don’t need to manipulate the pdf’s page label, we want only to read the original arabic/roman label.
We have the OEM Pdftron licence.

Thanks,

I’m sorry if I insist but it is really important for us to solve the problem

Hi there,

I checked with the team and this is a feature we do not and can not support in PDF.js Express. We only support this functionality using the Full API in PDFTron WebViewer.

Ok thanks for your answer,
I would like to ask you a question can we use the library with flutter?

Thanks,
Giuseppe
