Exporting as GIF/PNG image with transparency?

[KitchenKnives]

Hey guys, new user here. I'm not sure if this should be in Wish list or if the option exists and I just haven't uncovered it yet.

I'm not a railway modeller by any stretch of the imagination, but I am interested in graphic design and am currently focusing on map creation. I decided a good way to do this would be to use railroad design software (as I do have a passing interest in railways) and then design my map around the track patterns I come up with. I'm sure to those more knowledgable on the subject they'll look ridiculous, but whether or not they'd actually work isn't a big issue to me!

My ideal software for the rest of the map is Photoshop, so I was wondering if there's any way I can export the track layer alone, against a transparent background rather than the white default background. This would make it far easier to import to Photoshop and start painting under. Is this possible?

As an alternative, I could export as BMP or GIF then erase the white area myself, but the image would need to have anti-aliasing disabled for that to work reliably. I notice a lot of other railway design software lacks anti-aliasing, but I'm finding AnyRail so much more user-friendly I thought it'd be worth trying to stick with it, if I can.

Any tips, ideas?
Thanks in advance!

Welcome to AR!

Hmmmmm  .... would using a chroma key colour as the background of the track plan work?

I tried it just now, exported as a GIF imported in Photo-Paint, resaved the GIF and designated the Chroma Green as the transparent colour.

As you can see even though I had anti-aliasing selected when resaving the GIF there are green artifacts along the track.

It worked slightly better when using Chroma Blue. If it's good enough you need to decide.

Hey there,

Great idea I managed to get good results with the green chroma. I haven't tried the blue yet, but either way, very satisfactory! It's not 100% perfect so I'm still open to alternate methods if anyone has a bright idea they'd like to throw in, but until then I should be able to work with this.

Thanks again for the help.
