Let's say I have a room and I have placed a bunch of tiles inside.
Is there a way I can make it so Game Maker takes all of these tiles in the room (just the tiles), and saves it into
a background.png file? The rest of the room being transparent in the background file of course.

And no, I don't mean manually printing the screen in the room editor and doing it in photoshop,
I want to know if there is a way I can do this all in GML.

Can you be more specific? Like how big is the room in question? While playing the game, will you be able to view the whole room or a portion of it? Will there be objects obscuring some tiles? And what exactly do you intend to use the saved file for? I'd just like to get a handle on this problem.

I just want every tile that is placed in the room, to be some how saved into a background file.
Yes there most likely will be objects obscuring the tiles, however I can get them removed.
And no, the entire room sometimes will be bigger than the window itself.

I just want all the tiles to be put together, all tile layers, into one .PNG file.

Okay I think I get what you're asking now.
You could try using the screenshot save part function -screen_save_part(fname,x,y,width,height)- although I think you would have to make sure there are no objects obscuring the tiles in the room first. You just enter zero for the x and y coordinates and have the width and height parameters correspond with that of the room's. I think that might work. I haven't used GM so I may be wrong.

The only thing I would be careful of (assuming this function works the way I think it does) is to make sure that the room isn't too big.

EDIT: If you need more help just ask!

The most 'secure' way to do this is disable ALL object's visibility, setting draw target to a surface, and calling screen_redraw(). Game will draw all tiles into the surface nicely.

What do you mean by "setting draw target to a surface" ? and then using screen_redraw()?
I've never used surfaces before and I'm a bit confused on how I would get that into a file.
screen_save_part() seems like my best option though, but can you explain what you mean about surfaces...?
