Q: How can I save a web page to a bitmap?
A: Here's a code sample:
procedure TForm1.Button1Click(Sender: TObject);
var
ViewObject: IViewObject;
sourceDrawRect: TRect;
begin
if EmbeddedWB1.Document <> nil then
try
EmbeddedWB1.Document.QueryInterface(IViewObject, ViewObject);
if ViewObject <> nil then
try
sourceDrawRect := Rect(0, 0, Image1.Width, Image1.Height);
ViewObject.Draw(DVASPECT_CONTENT, 1, nil, nil, Self.Handle,
image1.Canvas.Handle, @sourceDrawRect, nil, nil, 0);
finally
ViewObject._Release;
end;
except
end;
end;

try

if viewObject = nil then
Exit;
OleCheck(viewObject.Draw(DVASPECT_CONTENT, 1, nil, nil, self.Handle,

// Resize the src bitmap to the target bitmap
targetDrawRect := Rect(0,0, tarWidth, tarHeight);

targetBitmap.Canvas.StretchDraw(targetDrawRect, sourceBitmap);
// Create a JPEG from the Bitmap and save it
jpeg.Assign(targetBitmap) ;
makeFileWriteable(jpegFQFilename);
jpeg.SaveToFile (jpegFQFilename);
finally
jpeg.free;
sourceBitmap.free ;
targetBitmap.free;
end;
except
// Error Code
end;
end;
