I seem to be missing something ? Please advise - Thanks in advance.

PDFLibrary.InsertPages(PageNo, 1);

Inc(PageNo);

ms.SetSize(0);

ImageEn1.IO.SaveToStreamJpeg(ms);

ImageID:= PDFLibrary.AddImageFromStream(ms, 0);

lWidth:= PDFLibrary.ImageWidth;

lHeight:= PDFLibrary.ImageHeight;

PDFLibrary.DrawImage(0, 0, lWidth, lHeight);

PDFLibrary.ReleaseImage(ImageID);

PDFLibrary.InsertPages(PageNo, 1);

PDFLibrary.SetPageDimensions(992, 1402); // A4

Inc(PageNo);

ms.SetSize(0);

ImageEn1.IO.SaveToStreamJpeg(ms);

ImageID:= PDFLibrary.AddImageFromStream(ms, 0);

PDFLibrary.SelectImage(ImageID);

lWidth:= PDFLibrary.ImageWidth;

lHeight:= PDFLibrary.ImageHeight;

PDFLibrary.SetOrigin(1);

PDFLibrary.DrawImage(0, 0, lWidth, lHeight);

PDFLibrary.ReleaseImage(ImageID);

Andy,

Note : ImageWidth and ImageHeight return the image size in pixels and the DrawImage function requires measurements in points.

You can refer to this post for a method of importing an image based on the DPI of the image -

Also 72points = 1 inch. So PDFLibrary.SetPageDimensions(842, 595); will set the page to A4 or PDFLibrary.SetPageSize('A4'); will also work.

Andrew.
