I would like to copy the images from one file to another.
To do this, I use DPLGetImageListItemDataToString and DPLAddImageFromString But DPLAddImageFromString returns systematically 0 regardless of the image What is wrong?

int docid = DPLLoadFromFileA(pdflib, "file.pdf","");
int res = DPLSelectPage(pdflib, page);
int ilid = DPLGetPageImageList(pdflib, 0);
int imageCount = DPLGetImageListCount(pdflib, ilid);
int ndocid = DPLNewDocument(pdflib);

for (int i = 0; i < imageCount; i++)
DPLSelectDocument(pdflib, docid);
DPLSelectPage(pdflib, page);
char *tmp = DPLGetImageListItemDataToString(pdflib, ilid, i + 1, 0);
double left = DPLGetImageListItemDblProperty(pdflib, ilid, i + 1, 501);
double top = DPLGetImageListItemDblProperty(pdflib, ilid, i + 1, 502);
double width = DPLGetImageListItemDblProperty(pdflib, ilid, i + 1, 503) - DPLGetImageListItemDblProperty(pdflib, ilid, i + 1, 501);
double height = DPLGetImageListItemDblProperty(pdflib, ilid, i + 1, 502) - DPLGetImageListItemDblProperty(pdflib, ilid, i + 1, 508);
DPLSelectDocument(pdflib, ndocid);
DPLSelectPage(pdflib, 1);
int imageId = DPLAddImageFromString(pdflib, tmp, 0);
DPLSelectImage(pdflib, imageId);
int res = DPLDrawImage(pdflib, left, top, width, height);
