I can't help but feel like there should be one more scale mode to choose from. It should be like letterbox integer scale mode but with cropping to extend to the edges of the screen... or rather there should be a zoom mode on crop. I want that pixel look but I want the screen to be filled.
Ideally I would simply make hi res "retro graphics" and use non integer scaling but that results in seaming (there won't be a fix to that right? Why not? it seems solvable to me I did it in xna..., but then again I am not sure I know how they implemented it in construct 2 and limitations with java script and stuff) <img src="smileys/smiley1.gif" border="0" align="middle" />
As a way of potentially doing this, you could use crop, and an event sheet to do the scaling yourself (with the "set layout scale action If I am correct"), you'd have to make the scaling only on integer values (and 1/integer values)
In this thread, I've made an exemple, not the best one, but should be enough to understand
