AGK for Pascal
TAgkImage.WrapU Property

Sets the UV wrap mode of the image when the U coordinate goes outside the range 0-1.

property WrapU: TAgkImageWrap;

The default is iwClamp, which clamps the pixel value to the last valid pixel. Mode iwRepeat repeats the texture starting from the opposite side. 

To use UV values outside 0-1 successfully on all platforms the image in question must be a power of 2 in width and height, and not be part of an atlas texture. This applies to both clamp and repeat.
