Hi mhieta,

I think you'll find everything you're looking for on http://www.melander.dk/delphi/gifimage/index.html

Just download the source and follow the installation instructions...

Good luck!

I've never heard of a patch or TTIFFImage object.

You can use the standard borland delphi3 TJPEGImage object to LoadFromFile a JPG picture:

Procedure TForm1.Button1Click (Sender:TObject);
var aJPG: TJPEGImage;
begin
     aJPG:=TJPEGImage.Create; {New JPEG Instance}
     if OpenDialog1.Execute then begin {If you've selected a filename}
          try
               aJPG.LoadFromFile; {Load the JPG from disk}
               PaintBox1.Canvas.Draw(0,0,aJPG); {Draw the JPG starting at (0,0)}
          finally
               aJPG.Free;
          end;
     end;
end;

The same construction is used for the TGIFImage:

Procedure TForm1.Button1Click (Sender:TObject);
var aGIF: TGIFImage;
begin
     aGIF:=TGIFImage.Create; {New GIF Instance}
     if OpenDialog1.Execute then begin {If you've selected a filename}
          try
               aGIF.LoadFromFile; {Load the GIF from disk}
               PaintBox1.Canvas.Draw(0,0,aGIF); {Draw the GIF starting at (0,0)}
          finally
               aGIF.Free;
          end;
     end;
end;

Use the Canvas.StretchDraw(TRect,Image) function to resize the pictures. You can not change the JPG's parameters. You'll need to copy the JPG to a TBitMap first, work on the bitmap, and then create a new TJPEGImage which is a copy of your bitmap.

Good luck!
