Does anyone have example code for translating a rectangular tile to an
isometrict tile? I'm a little lost on the math and can't seem to find a way
to transfer pixels from one TImage to another.

Hi Michael,

You shouldn't use TImage directly, but rather the Image.Picture.Bitmap
property and it's canvas.

The easiest way (assuming you have a TImage component named Image):

Iso := TBitmap.Create;
try
  Iso.Width := 100;
  Iso.Height := 100;
  with Image.Picture.Bitmap do
     Iso.Canvas.CopyRect(
       rectangle(0,0,Iso.Width, Iso.Height),  // Rectangle to copy to
       Canvas,                                           // Source canvas
       rectangle(0,0, Width, Height)); // Source rectangle
  // assign Iso back to Image
  Image.Picture.Assign(Iso);
finally
  Iso.Free;
end;

You can also directly access the pixels with Canvas.Pixels[x, y]; but this
is hideously slow.

Code is untested! Just wrote it out here.
