+GameMaker Studio lets you resize your rooms, but it does not offer any options for anchoring the existing content of the room when doing so. Your assets, instances, and tiles, will always be locked to the top-left of the newly-resized room.
 
 Now Roomsizer offers a traditional anchoring interface that should be familiar to users of any image editing software. No more resizing the room and then layer-by-layer dragging and dropping your content to the location you want it!

 If you are going to use Roomsizer **PLEASE** make sure you have a backup of your data first, or that your data is safely checked in to version control software like Git.
 
 There will be an effort to keep Roomsizer working on newer versions of GameMaker as they are released, but don't be careless with your valuable room data!

+Choosing the bottom-right point would have all the room's content in the bottom-right corner of the resized room, with all the additional space added on the top and left edges.
 Choosing the center point will add space evenly around the top, bottom, and sides, to keep content centered in the resized room.
 
 If you would like force your resize to a specific tile multiple without doing the math yourself, check the "Round up by tile size?" box, and enter the size in pixels of your tiles.
