Repeating background in cocos2d has black edges!

Question

I am attempting to setup a tiled/repeating background for my iPhone app.

The code "works" in that the background is repeating like it should be but I seem to have a black border around each repetition and I dont know why, the image is exactly 200x200. Here is a screenshot of how it looks along with the code:

if ((self=[super init])) {
    CCSprite * bg = [CCSprite spriteWithFile:@"pattern11.jpg" rect:CGRectMake(0, 0, 1000, 520)];
    [bg setPosition:ccp(0, 0)];
    ccTexParams params = {GL_LINEAR,GL_LINEAR,GL_REPEAT,GL_REPEAT};
    [bg.texture setTexParameters:&params];
    [self addChild:bg z:0];
}

Answer 1

Textures should always be in power of two... like 16,32,64,128,256,512,1024.

Try resizing the image to 256x256 or 128x128.
