I have an image I want to scroll in the background but when the images reaches the edge you can see the split where the image ends and the image begins. Is there a way to fix that through code or should I tell my artist to change the image.

Is the image you are using a power of 2 in size?

try changing the line agk::SetSpriteUVBorder( bgSprite, 0.5); to agk::SetSpriteUVBorder( bgSprite, 0); if this doesn't work can you post a screenshot of what you see

That background image is not "tileable", artist should fix it so left and right edges of the image match each other.

The quickest way to make it tileable is:

1: Cut the image vertically in the middle, or any other appropriate point
2: Switch each section to the other side (Right to Left and Left to Right)
3: Manually fix the join you just created in the middle, by blurring, cloning etc.

You now have a horizontally scrollable image. If you want it to scroll up and down, you need to do the same by cutting horizontally.
