Review: Gist Icon For Swift: Advanced Icon Processing For Ios Yesteryear Simon J Gladman

Who is the bulk for?

Core Image for Swift: Advanced Image Processing for iOS is for those iOS in addition to OS X programmers who cause got exclusively actually used Core Image out of necessity for when UIImage was non capable of providing a solution in addition to right away wishing to acquire further. It is also for those who are already acquainted alongside Core Image in addition to wishing to delve deep into the frameworks of Core Image in addition to Metal.

At every phase in addition to score of complexity the author, Simon Gladman, is in that place to guide us in addition to never exercise nosotros experience lone or laid adrift inwards this book.

First impressions

The start matter I noticed nearly this bulk was its purpose of the Apple textbook format. This gives it a clear in addition to concise feel. It is extremely visual, providing examples of the Core Image filters nether give-and-take (in static in addition to animated form) in addition to also clear code examples that are brusk in addition to readable.

This sense of clarity is carried through to the text itself. There are recommendations throughout on how to optimize the performance, in addition to it is oftentimes the fiddling things that brand the difference. These things laissez passer on the bulk the sense of beingness both accessible in addition to of providing a source of reference for many years to come.

Accompanying repositories

You volition run across from Simon's biog the many years that he has spent working alongside graphics in addition to icon technology, in addition to those working inwards Swift volition probable hold upward aware of the operate he has done alongside icon filters, including the Metal on iOS. The bulk of the operate he explores inwards this bulk in addition to inwards his blog exists on GitHub, and the repository written to accompany Core Image for Swift is in that place likewise nether the get upward Filterpedia. Throughout the operate in that place are signposts to these repositories.

The repositories supply fully working examples in addition to Filterpedia gives an immediate sense of the range in addition to flexibility of Core Image.

Areas of interest 

There are enough of areas of involvement inwards this book. To laissez passer on 1 example, I learnt that it is possible to exercise barcodes alongside the Core Image technology, something that had never caught my oculus inwards the Apple docs fifty-fifty though it interests me greatly.

In add-on to revealing the sheer range of possibilities, the bulk also holds the reader's involvement through what is almost a history of photographic styles in addition to technical restrictions. The reference points of the Apple II in addition to Commodore 64 are bully fun along alongside the simulation of watching a Cathode Ray Tube. We also larn the origins in addition to get upward of the Kuwahara filter. Simon's enthusiasm for experimentation shines through at every point.

Fine detail 

There are many points of fine technical detail. For example, the explanation of how filters tin hold upward chained together in addition to supply a combined calculation for their output rather than processing the icon fourth dimension in addition to again.

There are also practical points of implementation: at 1 indicate it is explained that when using an icon picker in addition to converting the UIImage from the photograph library to a CIImage the orientation volition change. (At this indicate the writer provides a most welcome drop-in solution for the issue!)

Conclusion 

It is clear that this bulk has been written alongside bully tending in addition to alongside affection for the subject. Not exclusively does it relieve us many hours of translation from Objective-C into Swift only it also takes the oftentimes hard to read Apple docs in addition to transforms them into something that nosotros tin all sympathise alongside clarity.

I've no uncertainty that every bit a reference resources every bit good every bit a straight-through read this book volition relieve many programmers non exclusively hours only also weeks in addition to months of their time. Helping optimization in addition to preventing bugs from arising.

Note: I volition presently hold upward submitting this review to hold upward my start postal service written natively inwards Apple News Format. I'll add together a link 1 time it is available.
