... topic: 314 Using gimp on turnouts posted: 15 Jan 2008 05:07 from: Adrian Following on from the post on Point rodding pics topic 169 I have been trialing the use of gimp to work out the geometry, so far with mixed sucess but I think I started at the deep end! So just reporting on progress. As a reminder the starting point!

It worked quite easily to get something that looked right. Unfortunately when loaded as a background shape in Templot it was difficult to get anything matching. I then realised that despite being careful on the use of the perspective tool I had mis-judged it slightly so I was getting gauge widening through the turnout. If I set the approach road to the right gauge then it'd be 8% to 10% out at the crossing. So now I use the measure tool in gimp to check the gauge is constant through ...
