Seems to be half pixel problem
« on: October 29, 2015, 04:30:52 AM »
When I place a image on the left-top corner at (0,0), there is a small gap on the top?
Is this the half pixel problem? How can I fix this? Thank you!

Most likely because your window's dimensions are not dividable by two. What is its size?

Yeah, I checked that and that's the problem. Thank you
Now I have another question. My sprite is 465*123, and it becomes 466*124 in the scene. Anything causes this?

1 pixel of padding is added automatically in order to make dimensions dividable by two, otherwise you can't center a sprite as it would fall in between of pixels.
