    * Graphics card. This is the big one. Your graphics card probably has anywhere from 256MiB to 2GiB of vRAM.  If blurry land is enabled and the map has a typical amount of empty space, you can make a map w/ ~2x the pixels as a card has vRAM. But. Most people don't like using Blurry Land, so best to limit to ~½ the pixels as a card has vRAM. Targetting support for people on 256MiB of vRAM, that means a 2:1 rectangular map should not be larger than 16,384x8192 which coincidentally fits in the SDL 1.2 width limit.

    * There is also a completely arbitrary check in game for widths/height < ~billion pixels which avoids possible integer issues, and a limit on size in pixels of 6 billion or so, which was just a basic sanity limit.  However given the limitations above, these are not likely to be reached.

  * Green (0, 255, 0) pixels are bouncy (since 0.9.20) and block portals (since 0.9.18). This mask can be used normally for maps or theme objects. If bouncing is implemented and the green pixels should only block portals, place a dotted line of single red or black or white pixels 3 pixels above the green, spaced 3 pixels apart each. This will keep most objects from interacting with the green, but prevent portal spawning.

It is recommended that your file _only_ consists of pixels which have one of the values above. This ensures that the masks works properly for your map and avoids unexpected behaviour. Also, it makes your file significantly smaller. [http://www.hedgewars.org/node/3339 Here] is a simple guide describing how you can ensure that.
