I am creating images from what I'll call chart cells - so that when in a
scroll pane scrolling is smooth. Currently it's not. So I use the following
method and load each into a UIImageView. Works great except the text in the
screens looks jagged. NO scaling is happening. Is there anything beyond
making the source 2x as large and then scaling down to fit? This is for
retina.
func translateToBitmap(item:ConCellView) ->UIImage {
UIGraphicsBeginImageContext(item.bounds.size)
item.layer.allowsEdgeAntialiasing = true
item.layer.renderInContext(UIGraphicsGetCurrentContext()!)
let chartImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return chartImage
}
