How to load a bitmap from disc into a dataset, using SDK v15 and Visual C++ 6.0 ???

I've been working with the Lead/Medicor Medical Imaging Suite SDK (v15) for a few weeks now under Visual C++ v6.0.

This must be straightforward, but I can't find any examples of doing it.
I need to load a bitmap file from disc into the PIXEL_DATA element.

The code I was trying is below, with questions contained within comments:


    LDicomDS*   pDS;
        pDS = new LDicomDS(szTempFilesFolder);
    pDS->InitDS(CLASS_VL_MICROSCOPIC_IMAGE_STORAGE, DS_METAHEADER_PRESENT |
                                                    DS_LITTLE_ENDIAN |
                                                    DS_EXPLICIT_VR |
                                                    DS_GROUP_LENGTHS);

    // I populate patient ID and all that other good stuff

    // now I need to load the BMP file into the dataset.
    // Don't know how.

    // This is what I started on reading about InsertImage() in the API

    pDICOMELEMENT pElement = NULL;
    L_INT32 lPhotoMetric    = IMAGE_PHOTOMETRIC_PALETTE_COLOR;
    L_INT32 lCompression    = IMAGE_COMPRESSION_JPEG_LOSSLESS;
    L_INT32 lBitDepth        = 8;
    L_INT32 lQuality        = 2;

    pBITMAPHANDLE pBitmap;

    // what here?? how do I load the BMP file from the know path into this BITMAPHANDLE?
   // you know, like I'd do this in MFC:
//     HBITMAP hBmp = (HBITMAP)::LoadImage(NULL, sPath,IMAGE_BITMAP,0,0,LR_CREATEDIBSECTION | 
    LR_LOADFROMFILE);       

    nRet = pDS->InsertImage(pElement, pBitmap, 0, lCompression, lPhotoMetric, lBitDepth, lQuality, DICOM_SETIMAGE_AUTO_SET_VOI_LUT, NULL, NULL);


    // now save it to a file.
    pDS->SaveDS(_T("c:\\test_dicom.dic"), 0);
    delete pDS;

EDIT: Additionally, why when I try to compile the above code I get unresolved external symbol errors during link? InsertImage() links fine, but SaveDS() does not:


DicomInterface.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: unsigned short __thiscall LDicomDS::SaveDS(unsigned short *,unsigned short)" (__imp_?SaveDS@LDicomDS@@QAEGPAGG@Z)
DicomInterface.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: __thiscall LDicomDS::LDicomDS(unsigned short *)" (__imp_??0LDicomDS@@QAE@PAG@Z)



Thanks!

To load the image, create an instance of LBitmapBase, call the Load function to load the image, then call GetHandle to get the BITMAPHANDLE.

As for the link error, SaveDS requires Ltdic_u.lib in your project.  You need to include it if you are not doing so.

Thanks Bashar.

edit: I had some more questions below about problems compiling, nevermind (if you happend to have already read them) I had failed to include LtWrappr.h

No problem.  Were you successful in loading the image?

Not yet - but that's because of the unresolved external symbol error I'm getting - I've posted another topic about that, here:

        http://support.leadtools...rums/10949/ShowPost.aspx

I'll update that thread in a bit. The demo at:

        C:\Program Files\LEAD Technologies\LEADTOOLS 15\Examples\API\Dicom

did compile successfully on my machine

I'm going to see if I can start a new project with the includes and see if I can duplicate it.

You should be able to solve the linking problem by linking to
LTWVC2_U.LIB instead of LTWVC_U.LIB.  Let me know if are still unable to solve this issue.
