try to insert an image to a PDF page, but failed

[Steven Lee]

Here is an example, I just found it does not call ProcessImage method at all, any wrong with my code, thanks.

FPDF_InitLibrary(NULL);

FPDF_DOCUMENT doc=FPDF_LoadDocument("d:\\PDFCreator_op.pdf",NULL);

FPDF_DOCUMENT newDoc=FPDF_CreateNewDocument();

int page_count = FPDF_GetPageCount(doc);

for (int i = 0; i < page_count; ++i) {

FPDF_PAGE page = FPDF_LoadPage(doc, i);

int width = static_cast<int>(FPDF_GetPageWidth(page));

int height = static_cast<int>(FPDF_GetPageHeight(page));

FPDF_BITMAP bitmap = FPDFBitmap_Create(width, height, 0);

FPDFBitmap_FillRect(bitmap, 0, 0, width, height, 0xFFFFFFFF);

FPDF_RenderPageBitmap(bitmap, page, 0, 0, width, height, 0, 0);

FPDF_PAGE output_page= FPDFPage_New(newDoc, i, width, height);

double ratio_x=1;

double ratio_y=1;

  // Add the bitmap to an image object and add the image object to the output page.

FPDF_PAGEOBJECT img_obj = FPDFPageObj_NewImgeObj(newDoc);

FPDFImageObj_SetBitmap(&output_page, 1, img_obj, bitmap);

FPDFImageObj_SetMatrix(img_obj, ratio_x, 0, 0, ratio_y, 0, 0);

FPDFPage_InsertObject(output_page, img_obj);

FPDFPage_GenerateContent(output_page);

//CPDF_PageContentGenerate tmp((CPDF_Page*)output_page);

//tmp.InsertPageObject((CPDF_PageObject*)img_obj);

//tmp.GenerateContent();

FPDFBitmap_Destroy(bitmap);

FPDF_ClosePage(page);

}

saveFile(newDoc,"d:\\zp11.pdf");

FPDF_CloseDocument(doc);

FPDF_CloseDocument(newDoc);

FPDF_DestroyLibrary();

Can you see the image object when you view the raw PDF?

[Steven Lee]

no. 

only in this way, image object can be insert, but can not show in pdf, seems need more job.

//CPDF_PageContentGenerate tmp((CPDF_Page*)output_page);

//tmp.InsertPageObject((CPDF_PageObject*)img_obj);

//tmp.GenerateContent();

Hello

This works for me...you need to resize the image
FPDF_PAGEOBJECT pdfImage = FPDFPageObj_NewImgeObj(mPdfiumDoc);

    FPDF_BITMAP bitmap = FPDFBitmap_CreateEx(img.width(), img.height(), FPDFBitmap_BGRA, img.bits(), img.bytesPerLine());

    FPDFImageObj_SetBitmap(&mCurrentPage, 1, pdfImage, bitmap);

    FPDFPageObj_Transform(pdfImage, img.width(), 0, 0, img.height(), pos.x(), mCurrentHeight - pos.y() - img.height());

    FPDFPage_InsertObject(mCurrentPage, pdfImage);

and finally do not forget generateContent at the end.
