Hi,
take this example of shrinking to half size.
var JpegImage : tJpegImage;
Bitmap : tBitmap;
begin
if OpenPictureDialog.execute then
begin
JpegImage := tJpegImage.Create;
Bitmap := tBitmap.Create;
JpegImage.LoadFromFile(OpenPictureDialog.FileName);
Bitmap.Height := JpegImage.Height div 2;
Bitmap.Width := JpegImage.Width div 2;
Bitmap.Canvas.StretchDraw(
Rect(0, 0, Bitmap.Width, Bitmap.Height), JpegImage);
JpegImage.Assign(Bitmap);
JpegImage.SaveToFile(OpenPictureDialog.FileName);
JpegImage.Free;
Bitmap.Free;
end;
end;
Regards from
Heiner

I have a page about thumbnails which should give you an idea.
