I have a PDF document from a scanner. The document contains images in JPEG2000 format. The Foxit Quick PDF Library returns BMP as image type (GetImageListItemIntProperty(imageList, imageNumber, 400) = 2) and displays the image as a black rectangle. 

My question: Can the Foxit Quick PDF Library render JPEG2000 images?

Hi Werner :)

It's a pdf library to handle and maintain pdf documents - not an image library ;-)
Nevertheless inside/internally it can work with the jpeg2000-format.
Below is a part from a source function:
procedure TPDFImageDecoder.LoadJPEG2000;
{$IFDEF NOJPEG2000}
begin
end;
{$ELSE}
var
  MS: TMemoryStream;
  JB: TJpeg2000Bitmap;
  Row: Integer;
  Col: Integer;
  CMYK: TPDFCMYKColor;
  RGB: TPDFRGBColor;
  RowData: array of Byte;
  IsCMYK: Boolean;
begin
  IsCMYK := False;
  JB := TJpeg2000Bitmap.Create;
  try
    MS := TMemoryStream.Create;
// ...

The real render functions of the library doesn't support jpeg2000.
Below you'll find the render options from the reference guide:
Options
0 = BMP output
1 = JPEG output
2 = WMF output
3 = EMF output
4 = EPS output
5 = PNG output
6 = GIF output
7 = TIFF output
8 = EMF+ output
9 = HTML5 output
10 = G4 TIFF output
