Hi everyone!
Im sorta new to thes forums and I was hoping i could get some help :)
I'm making a Tile Map Editor(2d) in VB.net(2005). I got the basics down, i.e, TileSetBrowser, TileMap, able to place tiles on the map, able to place multiple selected tiles on the map.
But i'm having a hard time with extra tools besides "Pencil". The tools i'm talking about are:
Square fill
Circle Fill
Line
Fill
its basicly like in paint except with tiles. ;)
Any help would be apperciated
Ok and what is your Question?
I dont understand what you are asking..

well since its Vb.net you can use
picturebox1.creategraphic.fillrectange
for the line you can set the inital coords in the mousedown event then draw the line to the current mouse position.
Not too sure Rich read your entire post, since you obviously can't use the graphic objects to (directly) place your tiles.
What you could do, if you did want to use a lot of concepts of paint programs is the following.
Create an off-screen bitmap/graphics object the same dimensions as the user's map.
Assign each tile type to a colour.
As the user edits the map update the graphics object appropriatly (each time a user places a tile(s) on the map).
To deal with more complex stuff (as you listed) you could use appropriate graphics methods (like the FillRectangle function Rich mentioned) to draw on the bitmap. You'd then scan for changed pixels and update your tilemap accordingly.
This method could be very quick for implimenting many different paint-like functions (as little as one changed line (the graphics method called) per function). Also, if you do go with the first method you could even display the graphics object as a small 'overview' of the user created map.However, if your map is very large then the update may take too long for it to be useful.
If that is the case you'd have to code each function yourself. It would be useful to search for info on these functions implimented in a paint program, since the method would be exactly the same. Instead of dealing with pixel colours you'd be dealing with tile types.
Well, if you got the basics right then you must have done it using Bitmap and Graphics class.
@SLH
What you said wouldn't be right.. I mean he can just make square by looking at point a and B and changing the tiles in beween.
The other ones I don't know. I'm guessing he stored the tile data in to an array like so, Tile(layer, x,y) = data. Thats how i would do it.
Why must he have used the Bitmap and Graphic class for a tile engine? He's placing tiles on a grid, not changing colours of pixels...Quote:

P.S. There's no right and wrong, just different ways of acheving the same thing, i suggested 2 ways.
