Skia is an open-source 2D graphics library that powers the graphics engine used by Flutter and the Android operating system. The implementation of Skia in Delphi marked a significant advancement for the FireMonkey framework, as it greatly surpasses the legacy Delphi TCanvasGPU graphics engine in nearly every aspect.
- Solid Graphics Foundation: Since Skia is the same graphics engine used by Flutter, apps built with Flutter or Delphi + Skia share the same foundational graphics technology.
- Performance: The Skia algorithms are optimized to the extent that they can often render directly onto the form surface without requiring an internal buffer.
- Cross-Platform Consistency: Skia offers a consistent graphics engine across all platforms (Windows, iOS, macOS, Android).
- Rich Features: Skia provides powerful capabilities typical of a robust graphics engine, including advanced text formatting and shadow rendering.
- Increased Package Size: Adding Skia increases the package size by approximately 25 MB.
- Dependency on Google: Skia is a Google product, and while Embarcadero has traditionally focused on offering an independent product free from GAFA domination, using Skia introduces a dependency on Google's technology.
- OpenGL Limitations: Under OpenGL, only raster images (CPU) can be shared across different threads. This means that GPU textures cannot be created in background threads and later drawn on the main form surface. Interestingly, there seems to be no noticeable speed improvement when drawing GPU images compared to raster images.
- Image Rendering Performance: While Skia excels at drawing shapes directly on the form surface, it is notably slower (4x more slower) than the legacy Delphi canvas (TCanvasGPU) when rendering images onto the form.
The slower image rendering is particularly problematic in scenarios where we paint everything first onto an internal buffer and then render that buffer to the form surface on each paint loop—a technique often used to avoid flickering and improve performance. Unfortunately, Skia can be up to 4 times slower at drawing images onto the form surface compared to the legacy Delphi TCanvasGPU, which uses OpenGL textures.
For example, on a Google Pixel 7, I can render 2000 textures simultaneously at 90 FPS using TCanvasGPU. However, with Skia, I can only render 500 images at the same frame rate. You can verify this using the demo app located at Demos/ALFmxGraphics.
Given these limitations, I’ve decided to use Skia as the backend graphics engine in Alcinoe while continuing to use the legacy Delphi canvas (TCanvasGPU) for rendering on the main form surface. The exception is on Windows, where we use Skia for both the backend and the main form surface.
On Android and iOS, the operating systems already provide
powerful graphics APIs, and in many cases, these native APIs
outperform Skia—often by as much as 2x. While the performance
of the OS graphics APIs is superior, Skia still offers the
benefit of a unified graphics engine across all platforms,
along with additional features like animated images.
In recent years, Material Design has emerged as a guiding design language for developers creating modern, user-friendly, and visually appealing applications. With the release of Material You (Material Design 3), Google has taken a step further by allowing greater personalization and a more dynamic appearance. Developers using Delphi can now leverage Material 3 principles to create stunning, cohesive interfaces across platforms like Android, iOS, Windows, and macOS.
TALButton offers full customization for states such as Enabled, Pressed, and Disabled, allowing for modern Material 3 button styles.

Both controls follow Material 3’s minimalistic and responsive design. They include customizable properties for checkmark, border, and shadow and utilize smooth transitions between states. Their highly customizable nature allows you to create checkbox and radio button components that align with Material 3’s aesthetic.
TALSwitch is designed for easy customization, allowing you to control the design of the switch in states such as Enabled, Hovered, Focused, Pressed, and Disabled. The control provides smooth, responsive transitions between on and off states, reflecting the fluid, adaptable nature of Material 3’s switches. The customizable design ensures that TALSwitch fits seamlessly into a modern, minimalistic interface, offering both visual appeal and optimized performance for Delphi applications.
TALTrackBar allows for extensive customization of its appearance and behavior, making it an ideal choice for implementing Material 3’s clean and modern slider design. You can easily customize the track and thumb with properties such as fill, stroke, and shadow to achieve the sleek, minimalistic look that defines Material 3. The slider's interactions, including value indicators and stop indicators, are smooth, ensuring responsive feedback as the user interacts with the control. Its transitions between states like Enabled, Focused, and Pressed contribute to a polished, fluid user experience.
Alcinoe’s native TALEdit and TALMemo controls are designed to match Material 3’s input fields, offering customizable border, shadow, and font properties. These controls adapt across platforms while maintaining a consistent, clean interface for text input, with features like autosizing and prompt text.
While Material 3 focuses on responsive and adaptive design, performance is equally important. Alcinoe’s double-buffered rendering ensures that your controls are fast and fluid, even during complex UI interactions like scrolling. This performance boost aligns perfectly with Material 3’s goal of seamless, responsive user interfaces.
Incorporating Alcinoe in your Delphi projects allows you to create modern, high-performance apps with a polished Material 3 appearance, without compromising on speed or cross-platform compatibility.

TALText is a robust component similar to TText, but with enhanced capabilities like basic HTML text formatting support. Despite incorporating HTML formatting, TALText delivers substantial performance improvements over TText. This is achieved through its double-buffered engine, which renders text on an internal buffer and then draws only the buffer onto the form during each paint cycle. This design ensures that TALText is extremely fast and efficient. Additionally, TALText enhances functionality by supporting mouse event handling, allowing it to detect specific HTML elements (such as span IDs and bounds) under the mouse pointer. This feature enables interactive text elements, making it ideal for applications requiring dynamic, responsive text behavior. Learn more at Demos/ALFmxControls
ALVideoPlayer renders video onto a texture, allowing seamless integration into a Delphi form while supporting Z-ORDER, enabling controls to be placed on top of the video. In contrast, Delphi’s official video players are native video player windows overlaid on the form, which do not support Z-ORDER.

An Android library, also known as an Android Archive (AAR), contains everything needed to build an app, including source files, resource files, and the manifest. Unlike JARs, AARs can include resource files in addition to compiled bytecode.
Integrating an AAR into a Delphi project can be a long and complex process, involving extracting resources, manually adding them to Delphi deployment files, compiling the R.java class, checking dependencies, and more.
With AndroidMerger, this entire process is automated in a single command line. In short, AndroidMerger will:
- Use Gradle or an internal implementation to list all dependencies.
- Download libraries and dependencies from local or central Maven repositories.
- Merge the resources of all AARs into a single directory.
- Combine the AndroidManifest files of all AARs into AndroidManifest.template.xml.
- Merge google-services.json into the project's resources.
- Create the R.jar with all resource IDs using aapt or aapt2.
- Update the project file (.dproj) to include all resources.
- Generate the Delphi native bridge file from the Java libraries.

In the constant evolution of software development, we often find ourselves seeking ways to reduce boilerplate code and enhance the maintainability of our projects. One such instance where boilerplate can become cumbersome is in the initialization of class fields. The traditional method involves explicitly setting each field's value in the constructor, which can be tedious, especially for classes with numerous fields. Enter TALInit—a feature that allows automatic initialization of object fields based on their attributes.
In the typical approach, developers manually initialize object fields in the constructor. Take the following class as an example:
TAutoInitObject = class(TObject)
public
CharValue: Char;
ChildObject: TChildObject;
public
constructor Create; virtual;
destructor Destroy; override;
End;
Here, each field is initialized in the Create constructor:
constructor TAutoInitObject.create(const aOwner: Tform1; const AAutoInit: Boolean);
begin
CharValue := 'A';
ChildObject := TChildObject.create;
ChildObject.Name := 'AnObject';
ChildObject.Value := 12.2;
end;
destructor TAutoInitObject.Destroy;
begin
ALFreeandNil(ChildObject);
inherited;
end;
While this method offers precise control, it can become tedious for large classes with numerous fields.
Imagine having a mechanism that not only automates this but is also as fast as the traditional way - yes, you read that right. TALInit achieves this remarkable feat.
TAutoInitObject = class(TObject)
public
[TALInit('A')]
CharValue: Char;
[TALInit('Name:AnObject;Value:12.2')]
ChildObject: TChildObject;
End;
By using custom attributes, every field within the object can be automatically initialized based on its corresponding attribute. This eliminates the need for manually setting each field within the constructor. The above snippet showcases just how concise and readable object field initialization can become with TALInit.
One of the strongest advantages of using TALInit is its performance. When introducing automation, a natural concern is the overhead that might come with it. However, TALInit is designed to be as efficient as the traditional way of initializing fields. This means developers can enjoy the convenience without having to worry about any hidden costs in execution time.

This is a Delphi driver with connection pooling for accessing a MongoDB server. Connection pooling refers to a cache of database connections that are maintained for reuse, reducing the need to establish a new connection for each request. Once a connection is created, it is placed in the pool and can be reused for future database requests.
If all connections in the pool are in use, a new connection is created and added to the pool. This approach reduces the time required to establish connections, enhancing performance and efficiency when interacting with the MongoDB database.

TALStringList functions similarly to Delphi's TStringList,
but with significant performance improvements. When the list is sorted,
it uses a quicksort algorithm to search for name=value pairs, enabling
much faster lookups.
Additionally, TALStringList uses a locale-independent sorting algorithm based on the 8-bit ordinal value of each character, rather than Delphi's AnsiCompareText and AnsiCompareStr. This results in sorting speeds up to 10 times faster than Delphi's TStringList.
Unlike TStringList, TALStringList is not Unicode-based but is a fully Ansi string list, optimized for performance.

There's no doubt that Unicode was necessary for a product like Delphi. However, the approach Embarcadero chose for its implementation has raised some concerns. Instead of adopting UTF-8 through 8-bit strings, they opted to migrate from 8-bit strings to 16-bit strings (UTF-16). This decision made migrating Delphi applications prior to D2009 challenging, especially for those that relied on the assumption that strings were 8-bit.
For more insights into why UTF-16 can be problematic, here's an excellent article: utf8everywhere.org.
Starting with D2009, AnsiString now has a code
page, and some transliteration occurs when assigning an
AnsiString with one code page to another AnsiString
with a different code page (e.g., OldCodePage => UTF-16 =>
NewCodePage). To prevent unwanted transliterations, it's
crucial to set the project's code page to the desired
one (e.g., 65001 for UTF-8) and call
SetMultiByteConversionCodePage(CP_UTF8) at the beginning
of the program.
Additionally, avoid mixing different string types
(e.g., UTF8String and AnsiString) even if they share
the same code page. The Delphi compiler doesn't recognize this
at compile time and will still perform unnecessary
transliterations (e.g., MyAnsiStringUTF8 := MyUTF8String
results in UTF-8 => UTF-16 => UTF-8).
To minimize these issues, it's best to use AnsiString
exclusively in your code, even when handling UTF-8 content.
Always ensure that AnsiString is paired with
SetMultiByteConversionCodePage(CP_UTF8) to prevent
undesired conversions.
