Preview picture for route in surveyor

[jytte]

I've been looking and looking for some info on this but can't find any. I must have found something at some point, because I have a note for myself that preview pictures must be 512x512 for surveyor, but can't find that again.

I add a thumbnail 240x180 to any asset I upload, would for route as well. That's what shows up in DLS and CMP. So far so good.

But what about the larger picture that shows up in Surveyor (the one that is supposed to be 512x512)?

I can find only a few routes on my PCs that actually shows a picture in Surveyor, Marias Pass and Hawes Junction do. They have the regular "thumbnails" lines in config.txt with a 512x512 jpg, but nothing else, not a 240x180 for DLS. Since these are built-ins they aren't on DLS anyway.
I can't find a route that has both, so I could see what that config might look like.

Can I add two thumbnails to config, One for DLS and one for Surveyor?
And will DLS/Surveyor then know which one is which from the size alone?
As usual, the Trainz guide offers no guidance.

for lack of answers, I went ahead and experimented with test board
I added 2 thumbnails, one 240x180 and one 512x512.

this is the config:

thumbnails {
0 {
image "carsthumb.jpg"
width 240
height 180
}
1 {
image "carsroute.jpg"
width 512
height 512
}
}


neither CMP nor Trainz protested, so I guess I'm ok on that part.
So now I get this beautiful piece of art in the surveyor list

unfortunately, this is the 240x180 thumbnail picture (stretched to fit the 512x512 box), not the one intended to be in here.

Uh, why do we have these options if they don't work? Or if they do, what am I missing?

Anyone done this successfully??

By trial and error it has been determined that you need to eliminate the lines
width 512
height 512
leaving everything else the same, and it should work for you. I know this goes against all common sense, but that is the way it is, and no one from Auran has ever bothered to explain why. If you put the 512's in it gets confused and always defaults to the smaller thumbnail.

I spent a fair time tearing my hair out over this one.

Thanks so much George!

I hope you have a little hair left (for future ventures) :hehe:

So, just to clarify for me, I can add 2 jpegs to the config, one as any other thumbnail for DLS, and then another bigger one without the lines "height/width", and then I should get the little picture in DLS, and the bigger one in Surveyor? And it will upload without problems?

 

[gfisher]

Yes, that is what should happen. Works for me.

Thanks again, George, that's what I'm going to do then.

EDIT: I tried it, and it looks good (the right pictures) in both CMP and Surveyor.
