How to insert an image in a pdf document

Question

I used the "Stamper" example and modified the fuction to insert image to my pdf doc.
PDAnnot CreateStampAnnotationAt(AVPageView pageView, AVDevRect *rect)
to add a picture Annotation into page.
when system calling the callback function "AnnotDraw" to draw the Cos Object in that Annotation ,the function "AVPageViewDrawCosObj(pageView, coApp, &avdr)" doesn't work.Here is the code:
ASFixedRect pdLocation;
PDAnnot annot = {0,0};
CosObj cAnnotObj, cIntObj, cStmObj, attributesDict, LengthEntry, cNullObj;
CosObj cAPDictObj, cStmDictObj, cBBoxObj, cProcSetObj, cResObj;
CosObj fontResObj, fontResObj2, cObj;
CosDoc cdoc;
ASStm stm;
char buf[512];
PDPage pdPage;
ASUns32 s;
ASFile picFile = NULL;
DURING
        //handle clicks (with no drag, or only in one direction), by creating a default size annot
        if((rect->top == rect->bottom) || (rect->right == rect->left))
                rect->top +=75;
                rect->right += 150;
        pdPage = AVPageViewGetPage(pageView);
        AVDoc avDoc = AVPageViewGetAVDoc(pageView);
        AVPageViewDeviceRectToPage ( pageView, rect, &pdLocation);
        // Add the new annotation to the page.
        annot = PDPageAddNewAnnot(pdPage, -1, Stamper_K, &pdLocation);
        cAnnotObj = PDAnnotGetCosObj(annot);
        cdoc = PDDocGetCosDoc(PDPageGetDoc(pdPage));
        // See PDF Specification for more information on the Flags key.
        cIntObj = CosNewInteger (cdoc, false, 4L);
        CosDictPutKeyString(cAnnotObj, Flags_KStr, cIntObj);
        cAPDictObj = CosNewDict(cdoc, false, 1L);
        cNullObj = CosNewNull();
        ASFileSysOpenFile (ASGetDefaultFileSys (),ASPathFromPlatformPath("c:\\test.jpeg"), ASFILE_READ, &picFile);
        stm = ASFileStmRdOpen (picFile, 4096);
        attributesDict        = CosNewDict(cdoc, false, 5);
        LengthEntry = CosNewInteger(cdoc, false,11594 );
        CosDictPutKeyString(attributesDict, Length_KStr, LengthEntry);
        cStmObj = CosNewStream(cdoc, true, stm, 0, true, attributesDict, cNullObj, s);
        cStmDictObj = CosStreamDict(cStmObj);
        CosDictPutKeyString(cStmDictObj, "Type", CosNewNameFromString(cdoc, false, "XObject"));
        CosDictPutKeyString(cStmDictObj, "Subtype", CosNewNameFromString(cdoc, false, "Image"));
        CosDictPutKeyString(cStmDictObj, "Width", CosNewInteger(cdoc, false , 151));
        CosDictPutKeyString(cStmDictObj, "Height", CosNewInteger(cdoc, false , 151));
        CosDictPutKeyString(cStmDictObj, "ColorSpace", CosNewNameFromString(cdoc, false, "DeviceRGB"));
        CosDictPutKeyString(cStmDictObj, "BitsPerComponent", CosNewInteger(cdoc, false , 8));
        cBBoxObj = CosNewArray(cdoc, false, 4L);
        CosArrayInsert(cBBoxObj, 0L, CosNewInteger(cdoc, false, 0L));
        CosArrayInsert(cBBoxObj, 1L, CosNewInteger(cdoc, false, 0L));
        CosArrayInsert(cBBoxObj, 2L, CosNewInteger(cdoc, false, 100L));
        CosArrayInsert(cBBoxObj, 3L, CosNewInteger(cdoc, false, 100L));
        CosDictPutKeyString(cStmDictObj, "BBox", cBBoxObj);
        CosDictPut(cAPDictObj, FaceNormal_K, cStmObj);
        CosDictPutKeyString(cAnnotObj, Appearance_KStr, cAPDictObj);

Answer 1

BMP image?
Or Is it possible to insert any text instead of image?
But I need to work just like the stamper sample present in sdk. that is when i click on the pdf document any text has to be inserted instead of the image. I should not be to type the text in the pdf, but it should work exactly similiar to the stamper sample, but text has to be inserted instead of an image.
How can this be done? Is it possible to do?
Please help.
