I am trying to apply a texture for my brush but i'm really having a hard time figuring how it is done.

Here's the image of my output.

I used an UIImage that just follows the touch on the screen but when i swipe it faster the result is on the right side "W", and on the left side that's the result when i swipe it slow.

i tried using the CGContextMoveToPoint and CGContextAddLineToPoint i don't know how apply the texture.

Is it possible to use UIImage for the stroke texture?

Here's my code

    UIImage * brushImageTexture = [UIImage imageNamed:@"brushImage.png"]; 
    [brushImagetexture drawAtPoint:CGPointMake(touchCurrentPosition.x, touchVurrentPosition.y) blendMode:blendMode alpha:1.0f];
