Vector vs. Raster - when to use which?

[Redrobes]

There are raster operations and vector operations and Xara can do both. If it loads in bitmaps and textures with them then its doing raster operations. Xara is a hybrid app. Although PSP, PS, Gimp are all hybrids too, I think Xara has what appears to be the best hybrid operations in its class. But you cant say that Xara is a purely vector app because your map is painting pixels by looking up into a bitmapped texture source - even if the shape your texturing is a vector shape that still essentially a raster operation. You can definitively say its a raster operation when you scale an image huge and it pixellates. Neither vector or raster is better in absolute terms they are just different. Some operations are easier to do vector and some raster. Having an app which does both does mean that you don't need to learn two apps but the point is that you need to know which operations are easy in either case. You can draw a line in raster apps and you can fill with pure vector patterns too and sometimes thats the right thing to do and other times its not so good but most would agree that its easier to draw and modify a line in a vector app and a patterns in a raster app. I don't think that its necessarily true that quick or realistic is the right split to say vector or raster as you can do either in either type of operation but some things are quicker in vector and some things and quicker in raster and likewise for realism too. Some things are easy to do in 3D and some things are really hard unless you do them in 3D - its just right tool for the job.

True, but just to pipe in here again for a second. Again, I am talking about what works for me. For me my realistic maps are better in raster, but I can do maps faster in vector. That's not an opinion, it is a fact based on knowing how I work (and I am obviously going to know how I work better than anyone else just the same as they know how they work better than I do).

Sure, my comments were more directed to GP and this line :-

created in Xara Xtreme, with never touching a raster application

C'mon, its part raster application too.

Edit -- actually Nomadic, your aware of what you find best between the two types which is great. Its the knowing that counts and not dismissing one over the other that is important and knowing when to go 3D or use an effect etc. Its about being aware of your tool set and your comfort with each. Chgowiz asked when to use this or that but the answer is dependent on each person and their ability and comfort with them. I use a significantly different set of tools to everyone else here and all I suggest is that people try out different stuff - at least try a raster and vector app or use the raster and vector parts of one app and try some 3D and a stamping token based tool etc. Each have their own pros and cons and no one app has it all. People who say 'I do everything in xyz app' (which is usually PS actually) are missing out.

@Nomadic - I wasn't critizing your process or what best works for you. My disagreement was based on the general state that raster is more real and vector is just faster... what works for you, works for you, I'm not criticizing that. (Vector is faster no matter whether you're creating line art or working with images and photographs)

@Redrobes - I guess I should rephrase that, in my mind a raster application is an image editor (like Photoshop or GIMP) and Xara is not an image editor. Its true it can incorporate raster images in its functionality - and its power to feather, bevel, add transparency in layers is vastly superior than to other applications in its same class.

However, there are many things I can do with Xara, that I couldn't do with other apps like CorelDraw and Micrografx Designer (my original vector app.)

I've also qualified myself saying that I do use Raster apps as need arises or using 3D apps for specific needs. Still Xara is always in my production workflow, though sometimes I use only Xara to create maps.

PS: to avoid pixelization, I always use as high a resolution an image file as I can whether a painted texture or photograph. I try to obtain large format 300 dpi graphics for all my textures when possible.

Yea I know, I was actually trying to avoid someone doing this (why I stated that I personally did it that way). But I am bad about not clarifying that my statement is a personal view. So people still had a bit of trouble understanding that I wasn't saying "raster=real vector=fast" I was saying "for me raster is better at real and vector is better at fast".

... at least try a ... stamping token based tool

What is that? There have been times when it would have been easier to "stamp" the patterns rather than futz with a layer/mask.

[Gamerprinter]

Lots of the lower end mapping apps are stamp based tools. Dundjinni is probably the best of that class of application.

:forehead slap: Duh. I should have known that, as I've used Dundjinni before. I was hoping for something a bit more flexible in terms of output (and something I can use on Linux!)

@Chgowiz-

Dungeonforge can run under wine and is a nice little stamp/tile mapping program (though it has its own limitations...)
