Let me first start by saying I am so grateful that people ( I really mean Mr. Face) with skill way way above mine having shared their efforts.
I am starting to use ELE2PNG to produce elevation PNG files which are then cut up to fit into the higher (more detailed) levels.
As many of you will know, (I say it here to allow other people to follow the train of thought) ELEPNG produces a 259 by 259 pixel tile. (not 256 by 256)
256 of it is the "Core" Data, Rows 2 to 257. The top row (258) is a copy of the bottom row (2) of the file above. Meanwhile my bottom row (1) is a copy of the top row (257) of the file below. Same idea for the sides {more on row zero later}
So I have a 256 core surrounded the first and last of its friends. This is done to make the join seamless. Just what the "devil row zero" does is beyond me, but it is not directly Core data.
At last we come to the issue. To make 4 higher level tiles I slice the 256 x 256 into four 128 by 128 tiles. Blow each them up to 256 and start to make the changes I need for landing pads and the like. A single level 12 has become 4 layer 13 tiles.
Wait a minute I do not have a 256 but a 259 to slice!!!
I could get "fireworks" to export row 2 to 129 and 129 to 257 and blow them up. So far so good
When I come to save the finished product I have the issue of adding a single strip from 4 other files to left, right, top, bottom AND putting that Zero row back.
Could there be a switch to ELE2PNG to give/take just the core 256.
Or does anyone else have a way of doing this.
I have looked at Imagemajik and while it seems to say it COULD do this I just could not get on with the documentation.
