Loading a Poster to a Movie Annotation

Question

Hi,
I'm trying to add a poster to my movie annotation because when it initially loads before playing, it is a blank rectangle.
So, I thought of creating a PDF with an image of the first frame of the movie to be displayed as a poster. However, this doesn't work. Is it posible to load a poster to this type of annotation or is there a better way of doing this?
Thanks,
Kristy

Hi Leonard,
The problem is I've created a poster [Ie: PDF] and created a loadPoster function that creates an XObject and adds the poster to the page. I used this procedure to place a poster for my 3D annotation, but for some reason, it doesn't seem to work for the movie annotation.
Heres my code which loads my Poster:
// Global definitions
bool gbUseExternalPosterFile = true;
// input poster file
#ifdef PLUGIN // code for Acrobat plugin. full path.
#if WIN_PLATFORM
char* posterPath = "C:/tmp/input/ImagePoster.pdf";
#else
char* posterPath = "/tmp/input/ImagePoster.pdf";
#endif
#else // PDFL SDK
char* posterPath = "ImagePoster.pdf";
#endif
// Load Poster Function
void loadImagePoster (PDDoc pdDoc, PDAnnot newAnnot)
DURING
CosObj formXObject;
if(gbUseExternalPosterFile == true)
// Form XObject generated from an external image PDF file
formXObject = GetFormXObjectFromFileByConversion(posterPath, pdDoc);
else
// using the internal PDF Form XObject, we get form XObject through watermark generation.
formXObject = GetFormXObjectFromFileByWatermark("", pdDoc);
// Specify the poster as appearance for the movie annotation
if (!CosObjEqual(formXObject, CosNewNull()))
CosObj cosAnnot = PDAnnotGetCosObj(newAnnot);
CosDoc cosDoc = CosObjGetDoc(cosAnnot);
CosObj apprDict = CosNewDict(cosDoc, false, 1);
// Set the stream object (now a Forms XObject) as the normal (N) key
// and add to the Appearance (AP) key.
CosDictPutKeyString(apprDict, "N", formXObject);
CosDictPutKeyString(apprDict, "D", formXObject);
CosDictPutKeyString(cosAnnot, "AP", apprDict);
HANDLER
char buf[256];
AVAlertNote(ASGetErrorString(ERRORCODE, buf, 255));
END_HANDLER
Then where I create my movie annotation and set its contents, I call the poster function. [The exact same procedure I used to load my 3D Annotation Poster] Only in this case, it does not work.
Please, any help would be great.
Im just wondering if I need to add an entry called "Poster" when setting up my movie annotation and set up my stream [which is my poster] to be loaded...
Ex:
// Key = Poster, Value = true [boolean]
CosDictPutKeyString(dictMovie, "Poster", CosNewBoolean(cosDoc, false, true));
