Delphi Cookbook, - Third Edition

By: Daniele Spinetti, Daniele Teti

Overview of this book

Delphi is a cross-platform integrated development environment (IDE) that supports rapid application development on different platforms, saving you the pain of wandering amid GUI widget details or having to tackle inter-platform incompatibilities. Delphi Cookbook begins with the basics of Delphi and gets you acquainted with JSON format strings, XSLT transformations, Unicode encodings, and various types of streams. You’ll then move on to more advanced topics such as developing higher-order functions and using enumerators and run-time type information (RTTI). As you make your way through the chapters, you’ll understand Delphi RTL functions, use FireMonkey in a VCL application, and cover topics such as multithreading, using aparallel programming library and deploying Delphi on a server. You’ll take a look at the new feature of WebBroker Apache modules, join the mobile revolution with FireMonkey, and learn to build data-driven mobile user interfaces using the FireDAC database access framework. This book will also show you how to integrate your apps with Internet of Things (IoT). By the end of the book, you will have become proficient in Delphi by exploring its different aspects such as building cross-platforms and mobile applications, designing server-side programs, and integrating these programs with IoT.

Showing complex vector shapes using paths

One of the biggest advantages of FireMonkey compared to VCL is its vector-based nature. Various visual parts can be created in FireMonkey using vector-based graphics (even if in some cases, using a bitmapped approach can be faster). In terms of vectorial graphics, there is a nice language called Scalable Vector Graphics (SVG) that allows you to define primitive shapes using a set of coordinates and not a raster image. This means that you can stretch the image without losing its resolution because the image is not actually stretched; it's completely redrawn using the new coordinates. That's it; the SVG file is made up of coordinates and mathematical formulae to join them.

Inside the SVG language, there is an element called SVG path. The path element is used to define a path. So, what's a path?

A path is a sequence of instructions...
