How do I install SVGIconImageList in Delphi?

Download the installer from the releases page, which automatically detects Delphi versions, installs sources, builds packages, and adds source paths. For manual setup, refer to the project site documentation.

Which rendering engine is fastest for SVG icons in Delphi?

Performance depends on SVG complexity; Skia4Delphi is generally fast, but Direct2D may outperform with certain icons. Check the performance table in the README for benchmarks with different icon sets.

Can I use animated SVG icons in FireMonkey apps with SVGIconImageList?

No, animated SVG support is only available with the SVGMagic engine, which is VCL-only. For FireMonkey, you can use other engines like Image32 or Skia4Delphi but without animation capabilities.

How to search and download icons from the web with SVGIconImageList?

In the component editor, select 'Add from WEB' to open a search form connected to iconify.design. You can search, preview, and download icons directly into your SVGIconImageList or SVGIconImageCollection.

SVGIconImageList vs IconFontsImageList: which should I use?

Choose SVGIconImageList for scalable vector graphics with advanced features like animation and dynamic recoloring. IconFontsImageList is better for simpler, text-based icon fonts if you don't need SVG-specific capabilities.

What Delphi versions are supported by SVGIconImageList?

It supports Delphi from XE3 to the latest version (13.1), for both VCL and FMX platforms, as indicated in the release notes and compatibility section, with regular updates for new Delphi releases.

How to migrate from a traditional ImageList to SVGIconImageList?

Use TSVGIconImageList as a drop-in replacement with auto-scaling icons. For better management, adopt TSVGIconImageCollection with TSVGIconVirtualImageList, especially from Delphi 10.3 onwards, to leverage virtual lists and per-list properties.

What is SVGIconImageList?

SVGIconImageList is a Delphi library that provides components and multiple rendering engines for integrating scalable vector graphics (SVG) icons into VCL and FireMonkey applications. It solves the problem of bitmap icons that don't scale well across different screen resolutions and DPI settings by offering resolution-independent vector icons with advanced styling capabilities.

Target Audience

Delphi developers building desktop applications for Windows (VCL) or cross-platform applications (FMX) who need modern, scalable icon systems with features like dynamic recoloring, grayscale conversion, and high-DPI support.

Value Proposition

Developers choose SVGIconImageList because it offers four different rendering engines (including unique animated SVG support), provides both traditional and virtual image list components, includes web icon search integration, and maintains compatibility with Delphi versions from XE3 to the latest releases.

Overview

Four engines to render SVG (Delphi Image32, SVGMagic, Skia4Delphi, Direct2D wrapper) and four components to simplify use of SVG images (resize, fixedcolor, grayscale...) for VCL and FMX platforms.

Use Cases

Best For

Modernizing legacy Delphi applications with scalable vector icons
Building high-DPI aware applications that need resolution-independent graphics
Creating applications with dynamic icon theming (color changes, grayscale modes)
Developing applications that require animated SVG graphics
Managing large icon sets across multiple forms or modules
Cross-platform Delphi development with consistent icon rendering on VCL and FMX

Not Ideal For

FireMonkey applications requiring animated SVG support
Projects needing a plug-and-play solution without manual engine configuration
Teams unwilling to manage dependencies on third-party libraries like Skia4Delphi or SVGMagic

Pros & Cons

Pros

Engine Flexibility

Offers four rendering engines including Image32, SVGMagic, Skia4Delphi, and Direct2D, allowing developers to choose based on performance needs and features like animated SVG support with SVGMagic, as detailed in the engine selection section.

Centralized Icon Management

TSVGIconImageCollection provides a single source for SVG images, enabling easy updates and consistency across virtual image lists, simplifying icon management in large applications, as described in the component overview.

Web Icon Integration

Includes a built-in service to search and download SVG icons from iconify.design via REST API, directly within the component editor, streamlining icon acquisition without external tools.

Animated SVG Support

Unique capability through the SVGMagic engine to render animated SVG files, a feature not commonly found in other Delphi SVG libraries, with dedicated demos showcasing animation control.

Cons

Manual Engine Configuration

Selecting a rendering engine requires editing the SVGIconImageList.inc file with specific defines, adding setup complexity and potential for errors, rather than a runtime or IDE-based selection.

Performance Trade-offs

Performance varies significantly between engines; for example, Image32 and Skia4Delphi are slower with blur effects, as shown in the performance comparison table, requiring careful engine choice for optimal results.

Limited FMX Animation Support

Animated SVG functionality is exclusive to the SVGMagic engine, which is only available for VCL applications, not FireMonkey, restricting cross-platform use of animated graphics.
