AcroForm rendering quetion

[Shawn]

Hi,

I use FPDF_RenderPage(dc, page, ...) to print PDF document. It works fine until I met the attached document and the filled out information is not printed. 

 From the metadata, it seems this document including AcroForm. I am wondering how to get this worked. Also try to enable v8 and XFA and the 

result is the same. 

After some investigation, I found the filled out information is there if the PDF is converted to an image. It looks like there are two steps rendering, one for 

page and one for form:

FPDFBitmap_FillRect(bitmap, ...);

FPDF_FFLDraw(formHandle, ...);

Also try to printing the same document with Chrome and the filled out information on the first page is missing, but other pages seems OK. I am not sure it is a 

bug of PDFium?

All in all, I am wondering how to enable form rendering for FPDF_RenderPage()? Thanks!

Here are list of functions when printing:

doc = FPDF_LoadMemDocument();

form = FPDFDOC_InitFormFillEnvironment();

FPDF_SetFormFieldHighlightColor(form, 0, 0xFFE4DD);

FPDF_SetFormFieldHighlightAlpha(form, 100);

FORM_DoDocumentJSAction(form);

FORM_DoDocumentOpenAction(form);

page = FPDF_LoadPage(doc);

FORM_OnAfterLoadPage(page);

FORM_DoPageAAction(page);

FPDFPage_Flatten(page, FLAT_PRINT);

FPDF_RenderPage(dc,page);
