[guofeng....@gmail.com]

 Hi, the coding as following: 

 // 初始化库

    FPDF_InitLibrary();



    //

    FPDF_DOCUMENT pdf_doc;

    pdf_doc = FPDF_CreateNewDocument();



    FPDF_PAGE pdf_page = FPDFPage_New(pdf_doc, 0, 900, 1200);



    FPDF_PAGEOBJECT page_obj = FPDFPageObj_CreateNewRect(0, 0, 300, 200);



    FPDFPage_InsertObject(pdf_page, page_obj);



    FPDFPage_GenerateContent(pdf_page);



How to save the document to a pdf file?

Take a look at FPDF_SaveAsCopy and FPDF_SaveWithVersion in fpdf_save.h.

I have seen FPDF_SaveAsCopy and FPDF_SaveWithVersion,  and both have a pointer of FPDF_FILEWRITE.

I don't know how to pass the name of the file I want to create and save.

Can you give me some assitance or examples?

PDFium has many tests that call FPDF_SaveAsCopy(). Some of them use
EmbedderTest::WriteBlockCallback() as part of their WriteBlock
callback. Is that a sufficient example?

Please also note there are several bugs related to FPDF_SaveAsCopy()
on our bug tracker.
