The LCD2.GDS Test File

We found an LCD layout and will use it as our test file. It is not likely to be as dense as our client's modern LCD layouts but it should have similar polygonal characteristics.

You can see a snapshot of the LCD2.GDS file below. Of course, the geometry is too dense to see any details at the full zoom level.

Initial Results

To match the client's request we used a tile size of 5 x 5 mm with a pixel size = 0.315 um (81,500 DPI) This results in a bitmap of 16,000 x 16,000 pixels for each tile.
