Overview of this book

FireMonkey (FMX) is a cross-platform application framework that allows developers to create exciting user interfaces and deliver applications on multiple operating systems (OS). This book will help you learn visual programming with Delphi and FMX. Starting with an overview of the FMX framework, including a general discussion of the underlying philosophy and approach, you’ll then move on to the fundamentals and architectural details of FMX. You’ll also cover a significant comparison between Delphi and the Visual Component Library (VCL). Next, you’ll focus on the main FMX components, data access/data binding, and style concepts, in addition to understanding how to deliver visually responsive UIs. To address modern application development, the book takes you through topics such as animations and effects, and provides you with a general introduction to parallel programming, specifically targeting UI-related aspects, including application responsiveness. Later, you’ll explore the most important cross-platform services in the FMX framework, which are essential for delivering your application on multiple platforms while retaining the single codebase approach. Finally, you’ll learn about FMX’s built-in 3D functionalities. By the end of this book, you’ll be familiar with the FMX framework and be able to build effective cross-platform apps.

Managing images effectively

Every UI has to deal with images sooner or later. Images can be part of the data you need to handle in the application or part of the UI's elements. Today's minimalistic trend pushes UI toward icons and glyphs with respect to text since a (well-chosen) image is usually more immediate to the user, can be quite convenient in terms of occupied space, and is usually less impacted by language switches.

In this section, we will learn about the components and capabilities the FMX framework offers so that you can effectively deal with images in your applications.

In FMX, we can deal with images through different functionalities and components. A TImage component (collocated on the Shapes page of the Component Palette section, even if it is not a descendant of TShape) is designed to show a single image and provide some typical functionalities (see the WrapMode property) to properly display the image on the screen.

A TImageViewer component can be...
