Related to GraphicsImportSetDataHandle API

Hi,

    I want to draw the JPEG image (which is in Memory) onto Gworld

using correspoding image importer component. Handle to the memory is 

available and image importer handle has been set using

GraphicsImportSetDataHandle. The code snippet is shown below.

Everything is fine till GraphicsImportDraw. But GraphicsImportDraw

is returning codecBadDataErr (-8969). When GetGraphicsImporterForFile

is used to open the same file then GraphicsImportDraw is successful and 

showing the image on window.

    Pls suggest why this error is occurred and how can it be fixed?

        Handle imageDataHandle = 0;

        //err = GetGraphicsImporterForFile( &theFSSpec,        &importer );

        theFile = fopen("Part 1:data6.jpg", "r");

        fseek(theFile, 0, SEEK_END);

        dataSize = ftell(theFile);

        fseek(theFile, 0, SEEK_SET);   

        imageDataHandle = NewHandleClear(dataSize);

        i = fread(*imageDataHandle, 1, dataSize, theFile);

        err = OpenADefaultComponent(GraphicsImporterComponentType, kQTFileTypeJPEG, &importer);

        if(err == noErr)

        {

               result = GraphicsImportSetDataHandle(importer, imageDataHandle);            

        }

        err = GraphicsImportGetNaturalBounds( importer,  &bounds );  

        OffsetRect( &bounds, 10, 45 );

       window = NewCWindow( NULL, &bounds, "\pDraw Image", true, documentProc, (WindowPtr)-1, true, 0);      

        err = GraphicsImportSetGWorld( importer, GetWindowPort( window ), NULL );             

        err = GraphicsImportDraw( importer );                 

        CloseComponent( importer );

        DisposeHandle(imageDataHandle);

Thanks and Regards,
