Thanks for the recommendation - and it is nice to see that you are so keen on it.
But, as I promised Redrobes, I have already tried it. I found it incredibly slow and I can understand why you found personal tutorials helpful. It may be that there was a conflict with something else on my machine, or it may be that it doesn't like lots of other stuff running concurrently, or it may be that it wants a more powerful graphics card to do the zooming - but my machine is reasonably powerful (dual core, plently of RAM) though, as I'm not a gamer, not a very powerful graphics card (does have 512mb RAM though). When I try a new prog and don't get on with it, I nearly always leave it there and might, or might not, revisit it again - but I uninstalled ViewingDale within the hour.
Well, I'm not sure I understand the bit about the DF grid being a cage. You can rescale any object on the map at any time. There's no equivalent zoom (though the VD one was too slow for me to be usable), but you can decide what pixel size the grid runs to when you set the map up (anything from 20x20 to 512x512 - which means it can go much more detailed than nearly all the images available on the net) and obviously it is up to you what scale the grid represents. You do have to set the map size in advance though (but it can be much bigger than most practicable uses).
I didn't really see VD being a tile mapper but more of an image placer (I might be wrong on this though). If that's the case, then the grid has a different function in the two progs. In DF the grid/cell size is primarily set to manage the initial scaling of objects, BUT it's main use is to enable tiling. You can use the grid for maps/battlemaps etc, but you don't have to, and could always overlay a grid of a different size.
I don't see how VD can handle extra detail; DF can handle any size/detail image out there, as tiles or objects, at a decent speed (and the maximum cell size could always be upped, if it proved a restriction in the future).
What VD does have though, is the zoom feature. I can see that would be very useful if it works for you. It also seems to work as a campaign/terrain mapper, whereas DF is primarily a battlemap prog (MapX being the one with the campaign/terrain features). DF is also limited in terms of building shapes etc; it is possible to work around this - and can be done fast with some prior preparation - but it doesn't do it 'out of the box'.
DF is free though; VD is $27 (approx). You make your choice and pay, or don't pay, your money.
I'm not intending to be negative about VD generally - it just didn't work well on my system though it clearly does on lots of others, including yours.
No need to worry about that
Do remember that I'm just a user; didn't program, couldn't program: I use lots of graphics progs (including Photoshop, GIMP, the Corel progs, Inkscape etc etc) which I use for a lot of things including maps. I agreed to keep DF/MapX available and will do that whatever progs I use, or whether I do any mapping at all; I'll also help people out if they have any problems. I also keep DungeonCrafter 1 & 2 (& image sets) available, though not DC3 as I don't have permission for that; long time since I used DC to actually do a map I wanted to use. I also occasionally visit and contribute to the DC3 forum - rather more than the Crew have done Where possible, I try out all the other progs that seem worth trying as they become available and certainly read feature lists, reviews etc.
Have tried DJ, but found it too slow and 'clunky' for me, and very limited in terms of map size and cell size (though I mostly do small maps now for use in BRPG). Lots of nice features, and DJ2 might have been interesting - if it had ever seen (will see?) the light of day. Certainly better than DF for its feature set, and worse for speed, map and cell size and price.
Haven't actually tried CC3 as there doesn't seem to be a trial and I'm not keen on getting to try it by paying money over first and getting it back if I don't like it. How many of the various packs would I really want? Would I want to buy everything just to see (with the 15% discount) and then get the money back and rebuy those packages I want? Too many decisions for me to get that far. Also put off a bit by complaints abouts its complexity - and I do see that its very long history might have become a bit of an obstacle in development terms - but I've never really had any problems with complex progs or CAD progs so I'd be quite confident of managing it fast enough (ie within the 14 day cashback limit). Some quite attractive symbols and maps though. And the zoom looks good.
Of the commercial RPG mapping progs, the one I'd be mostly likely to hand cash over for is FM8. Really a functioning superset of MapX rather than DF, though I don't remember it doing tiling (I need to have another look). Zoom very good, easy to use (at least I found it easy); might still use DF for some/many of the battlemaps if I were using it. Don't like the look of the symbols as they appear published or in the trial though - but then no real need to use them.
And for a fair few maps, I will use Photoshop et al for all or part of the process as many people here do. But I don't find these progs as fast as these purpose designed RPG mappers for producing 'realistic', atmosphere enhancing battlemaps.
Will probably have another look at MapTools soon. BRPG's own mapping ability has improved over time, and I assume MapTools will have done too, though I don't expect VTTs to compete with mapping progs for basic mapping.
I'll have a look at that - though not to the extent of reinstalling - any extra info on it on a working system will be good to have.
