Property Value

Type	Description
TdxPDFImageList	The collection of images on the PDF document page.

Remarks

Use the Images field to access individual images on the page by their indexes.

Example

You can use an image collection item’s Bitmap property to download a copy of an image on a PDF document page.

Delphi

var
  ABitmap: TBitmap;
begin
  if not dxPDFViewer1.IsDocumentLoaded then Exit;
  // Obtains the first image on the first document page as a bitmap
  ABitmap := dxPDFViewer1.Document.PageInfo[0].Images[0].Bitmap;
  if ABitmap <> nil then
    ABitmap.SaveToFile('D:\Image0.bmp');  // Saves the obtained bitmap as the Image0.bmp file on the D drive
end;

C++

TBitmap *ABitmap;
//...
  if(!dxPDFViewer1->IsDocumentLoaded()) { return; }
  // Obtains the first image on the first document page as a bitmap
  ABitmap = dxPDFViewer1->Document->PageInfo[0].Images->Items[0]->Bitmap;
  if(ABitmap != NULL)
    ABitmap->SaveToFile("D:\Image0.bmp");  // Saves the extracted bitmap as the Image0.bmp file on the D drive

Refer to the following topic for additional information: How to: Extract Content from PDF Documents.

Note

You cannot obtain images from a page if one of the following conditions is met:

• Content extraction operations are forbidden for the loaded PDF document (the Images field value is nil (in Delphi) or nullptr (in C++Builder)).
• The PDF document page has no images (the Images.Count property returns 0).
