TPdfObject.GetImageRaw

Declaration

function GetImageRaw(const Dest: TFilename): Boolean; overload;
function GetImageRaw(Dest: TStream): Boolean; overload;
function GetImageRaw(Dest: TIEBitmap): Boolean; overload;

Description

Returns the raw stream of an image within the current page to a file, stream or TIEBitmap.

Note:
◼The raw format will return an image with an undetermined compression and type
◼The TIEBitmap overload will fail if the image cannot be loaded
◼Use GetImage to reliably return the image of an object

Example

// Show preview of an image in the current PDF page
if objType = ptImage then
begin
  bmp := TIEBitmap.Create();

  // Try raw if possible
  haveBMP := ImageEnView1.PdfViewer.Objects[idx].GetImageRaw( bmp );

  // Fall-back to bitmap
  if not haveBMP then
    haveBMP := ImageEnView1.PdfViewer.Objects[idx].GetImage( bmp );

  if haveBMP then
  begin
    ImageEnView2.Assign( bmp );
    ImageEnView2.Fit( False );
  end;
  bmp.Free();
end;
