Hey guys,
I've searched a fair amount in the forums but don't see this exact issue.

These are small images, 37x25 hexes (for an "internal" size of 24). They are saved as PNGs with zero opacity in the empty areas on the right and left. I've used them in other projects/languages with no issue.

In this pic, they are loaded as Sprites and drawn adjacent to each other perfectly, and I haven't modified the sprite transparency. However as you can see, there is still some "bleed" on the right and left sides that looks like overlap. This only shows up if I either increase the zoom to over 1, or I play it in the Android player.

I've experimented with the drawing coordinates in both AppGameKit and with changing the image canvas itself (and adjusting or centering the bits to draw), but can't seem to make a difference.

Does this ring a bell for anyone?

Thanks

It sounds like your problem is because of the linear interpolation going on during scaling. Does the following fix your problem?



If you're scaling the images a lot though, they may become unacceptably pixelated from doing this..

Sorry, running on Windows and Android.

Lucas, thanks! That was exactly it! So I guess images default to Linear?
