Hi

This is a quite simple problem and I'm sure there'll be a demo that shows you how but if there is I cant find it...

I am creating thumbnails for a web site (adapting the "ResizeConvert" demo) and would like to add a simple black 1 pixel border around each thumbnail before I save it. What would the best way to do this?

The "Picture Frame" demo doesn't help because the thumbnail will vary in size at times and the mask is fixed.

Hi,
having an image into TImageEnView you can use bitmap canvas to draw the border:

  with ImageEnView1.IEBitmap, Canvas do
  begin
    Pen.Color := clBlack;
    Pen.Style := psSolid;
    Brush.Style := bsClear;
    Rectangle(0, 0, Width, Height);
  end;
  ImageEnView1.Update();
