How do i make it delete the picture?
proc
    tilePNG(var/atom/tile,width,height,var/atom/location)
        width /= 32
        height /= 32
        var/x = location.x
        var/y = location.y
        var/z = location.z
        for(var/widthprog = 0,widthprog < width,widthprog ++)
            for(var/heightprog = 0,heightprog < height,heightprog ++)
                var/atom/temp = new tile(locate(x+widthprog,y+heightprog,z))
                temp.icon_state = "[widthprog],[heightprog]"

You could either use block() to delete all of the pictures in a block of turfs, but since you're using /atom there's no good way of insuring it's actually the picture, except for checking its icon.
    deletePNG(del_icon)
        for(var/atom/A)
            if(A.icon == del_icon) del(A)


This is just an example, you'd call this delPNG('icon.dmi') to remove all of the atoms with the icon 'icon.dmi'.

Nice for() Nadrew..

Hn, do you think NRP should make a new type path so it would make it easier to find and delete the tiled PNG?

Example of what I mean: 
tiles
  parent_type=/atom


Now there's a path /tiles which has the same capabilities of /atom but it would be easier to search for and delete:
...
tilePNG(...)
   var/tiles/temp = new tile(locate(x+widthprog,y+heightprog,z))
    ...

removePNG(lowerloc,higherloc)//just an example
  for(var/tiles/T in block(lowerloc,higherloc))//loops through lowerloc to higherloc (look at <tt>block()</tt> if you don't know/remember), looking for object with the path /tiles
    del(T)//deletes it

I was just giving him a starting point. I was actually going to mention that looping over all atoms is a bad idea and that he should make a child-type or datum for it after the code itself, but I got in a hurry and just submitted after the code was typed up. Thanks for covering me, I hate when life makes me hurry, I have too much on my mind to remember things when I have to hurry.

ym gohost can you explain your code

Hn, I'll try.

You know there's the default: /datum,/sound,/icon,/image,/atom,/area,/turf,/atom/movable,/ obj,/mob

You can have your own /path by doing this:
Path_name_here
   parent_type=/pick/default/path/here


Lets say I want the path /item as a /obj
item
  parent_type=/obj//this makes 'item' a path and it falls under the obj herarchy (sp?)



And let's say I have a path set up as /mob/NPC/Enemies/Special and I want to make it shortened down to /SEnemy without losing the path that has been set up:
SEnemy
  parent_type=/mob/NPC/Enemies/Special

Fine, *changes /dantum to /datum... there, fixed ... I don't know why I keep saying datum as dantum >_>''

And NRP, I can't think of a better example, a worse one (well, not really) is something like the following:
for(var/tiles/T in world) del T


It looks for all /tiles types and deletes them.. >_>

Now you made me feel dumb :/

Since you're using code I gave you, here's an updated version of the same procedure.

proc
    ceil(n, div) return n + n % div
    

tilePNG(atom/tile,width,height,turf/location,x,y,z,save)
        width = ceil(width, 32) / 32
        height = ceil(height, 32) / 32
        var/list/L

        if(save)
            L = list()

        if(isturf(location))
            x = location.x
            y = location.y
            z = location.z
        for(var/widthprog = 0,widthprog < width,widthprog ++)
            for(var/heightprog = 0,heightprog < height,heightprog ++)
                var/atom/temp = new tile(locate(x+widthprog,y+heightprog,z))
                temp.icon_state = "[widthprog],[heightprog]"
                if(save)
                    L += temp

        if(save)
            if(save==1)
                return L
            save += L



tilePNG(atom/tile,width,height,turf/location,x,y,z,save)

atom/tile = any atom that's icon is a png
width = width in pixels of that png
height = height in pixels of that png
turf/location = a turf to where it will place the bottom-left most corner of the image
x, y, z = the x, y and z of where it will place the bottom-left most corner of the image. If location is set to null it will use these instead
save = if this is set to null then it will not keep a list of the atoms used to make the png. if this is set to 1 then it will return a list of the atoms used to make the png. if this is set to an existing list it will add the atoms used to make the png to the existing list.



Examples of how to delete the picture:

var/list/thepicture = list()
tilePNG(turf/picture,200,1337,null,1,1,1,thepicture)
sleep(100)
for(var/turf/T in thepicture)
    del(T)

or
mob
    var/painting = list()
    verb
        paintMasterPeice()
            painting = tilePNG(turf/painting,640,640,locate(src),1,1,1,1)

        stunYourCritics()
            for(var/turf/T in painting)
                del(T)
            painting = list()
turf
    painting
        icon = 'monalisa.png'


That, uh, should work. If anyone can see any rubbishness in my code, please point it out.
