How to create a new uiimage using ciimage?

To create a new UIImage, for example: A CIImage is a immutable object that represents an image. It is not an image. It only has the image data associated with it. It has all the information necessary to produce an image.
Next, can a ciimage be converted to a uiimage?
Typically you can take NSData object containing a PNG or JPEG representation image and convert it to a UIImage. To create a new UIImage, for example: A CIImage is a immutable object that represents an image. It is not an image. It only has the image data associated with it.
In addition, how to use ciimage as a Core Image? You typically use CIImage objects in conjunction with other Core Image classes such as CIFilter, CIContext, CIColor, and CIVector. You can create CIImage objects with data supplied from variety of sources such as Quartz 2D images, Core Videos image, etc. It is required to use the various GPU optimized Core Image filters.
Additionally, how is a ciimage object different from an image?
Although a CIImage object has image data associated with it, it is not an image. You can think of a CIImage object as an image “recipe.” A CIImage object has all the information necessary to produce an image, but Core Image doesn’t actually render an image until it is told to do so.
Just so, what do you use ciimage object for in Photoshop?
You use CIImage objects in conjunction with other Core Image classes—such as CIFilter, CIContext, CIVector, and CIColor —to take advantage of the built-in Core Image filters when processing images.

Why are cicontext and ciimage objects immutable?

A CIImage object has all the information necessary to produce an image, but Core Image doesn’t actually render an image until it is told to do so. This lazy evaluation allows Core Image to operate as efficiently as possible. CIContext and CIImage objects are immutable, which means each can be shared safely among threads.

How to load uiimage class in ios 8?

The following image formats are supported by the UIImage class: Starting with iOS 8, the M:UIKIt.UIImage.FromBundle (System.String,Foundation.NSBundle,UIKIt.UITraitCollection) method can be used to load a UIImage that takes into consideration a UITraitCollection. This can automatically load the proper image for the specified resolution.

Why does uiimage draw an image upside down?

UIImage contains a CGImage as its main content member as well as scaling and orientation factors. Since CGImage and its various functions are derived from OSX, it expects a coordinate system that is upside down compared to the iPhone. When you create a UIImage, it defaults to an upside-down orientation to compensate (you can change this!).
