If you mean text, currently text with writing mode fonts are converted into images.

Text with type 3 fonts are experimentally supported, which must be turned on manually during compiling.
Please refer to the pdf2htmlEX wiki for instructions (see 'Building')

Most likely they are IMAGES in the PDF instead of text.

Hi Lu:

 

i convert a pdf to html on  an other computer . it happend "Internal Error: Attempt to output 2147483647 into a 16-bit field. it will be truncated and the file may not be useful. "

the system alert a error window : the pdf2htmlEX.exe has stopped working.

what is reason?

[Lu Wang]

I've seen the error before, but I'm not sure about it myself.
Please check the version of Fontforge you are using (run `pdf2htmlEX -v`), if it is older than 201209xx, probably it's too old, and you'd better update it.

As you say,this version should not exist the problem. but .......

 

An other question troubled me a long time.Can you help me ?please.

Question: Can we extract structrued data from pdf file ?this question about pdf structre ,but pdf2htmlEx .

example: there is  a pdf article . can we extract title、Paragraph、Image、Table of content and so on  from the pdf .

[Lu Wang]

So I cannot give a quick fix then, would you please file a issue on GitHub, with a sample file?

What I can tell is it must be coordination system calculation during font conversion, but I'm not sure if it's a bug of pdf2htmlEX or fontforge.

About your second question, there's no such data info stored in PDF as far as I know, after PDF is mainly designed for displaying and printing. Generally recognizing the structure is a diffcult task, and I'm afraid that I don't know any promising technique so far.
