Programmatically create image from UILabel

Question

I want to use a UILabel to create an RGBA stream of bytes image representation programmatically (at runtime).

For example, I want to create a UILabel in a specific

Answer 1

CGFloat scale  = [[[view window] screen] scale];
CGRect  bounds = [view bounds];

CGColorSpaceRef space = CGColorSpaceCreateDeviceRGB();
CGContextRef ctx = CGBitmapContextCreate(NULL, CGRectGetWidth(bounds) * scale, CGRectGetHeight(bounds) * scale, 8, CGRectGetWidth(bounds) *
scale * 4, space, kCGImageAlphaPremultipliedLast);
CGContextTranslateCTM(ctx, 0.0, CGRectGetHeight(bounds) * scale);
CGContextScaleCTM(ctx, scale, -scale);
[[view layer] renderInContext:ctx];

Then, use the bytes via CGBitmapContextGetData(myContext). No reason to bother with a UIImage
