IconFontsImageList
A Delphi component library for using icon fonts as scalable, colorable images in VCL and FMX applications with full high-DPI support.
What is IconFontsImageList?
IconFontsImageList is a Delphi component library that allows developers to use icon fonts as scalable and colorable images within VCL and FMX applications. It solves the problem of managing bitmap icons by providing vector-based icons that can be easily resized, recolored, and integrated into Delphi projects with full high-DPI support.
Delphi developers building VCL or FMX desktop applications who need modern, scalable iconography without relying on bitmap images.
Developers choose IconFontsImageList for its seamless integration with Delphi's native components, full high-DPI support, and the ability to use icon fonts for scalable, customizable icons, reducing application size and improving visual quality.
Overview
Four advanced components to simplify use of Icon Fonts as images and ImageList: TIconFontImage, TIconFontsImageCollection, TIconFontsVirtualImageList, TIconFontsImageList (for VCL and FMX). Full support for High-DPI apps. Rendering optimized with GDI+
Use Cases
Best For
- Modernizing legacy Delphi applications with scalable icons
- Building high-DPI compatible VCL or FMX applications
- Replacing bitmap icons with vector-based icon fonts
- Creating customizable UI icons with dynamic color and size changes
- Developing single-form Delphi applications with simple icon management
- Integrating Material Design or other icon fonts into Delphi projects
Not Ideal For
- Multi-form Delphi applications requiring optimized memory usage and performance with virtual image lists
- Projects using Delphi 10.3 or later that can leverage native TVirtualImageList for better scalability
- Teams needing automatic installation across all Delphi versions without manual setup for legacy versions like Delphi 7
- Applications that frequently update icon fonts and require seamless handling of font changes without deployment issues
Pros & Cons
Pros
Full support for high-DPI displays ensures icons scale correctly across different screen resolutions, as emphasized in the README for modernizing Delphi apps.
Uses GDI+ for improved visual quality and performance in VCL applications, reducing aliasing and enhancing icon sharpness.
Compatible from Delphi 7 to Delphi 13 across 32-bit and 64-bit platforms, making it versatile for legacy and new projects.
Replaces bitmap icons with icon fonts for easy resizing, recoloring, and reduced resource overhead, as shown in demos with Material Design fonts.
An automatic installer detects Delphi versions and sets up components, though it excludes Delphi 7 which requires manual steps.
Cons
TIconFontsVirtualImageList creates all images on demand, leading to slower performance and higher memory usage compared to native TVirtualImageList, as admitted in the README's warning.
The installer fails for Delphi 7, requiring complex manual installation via wiki instructions, adding overhead for teams with older codebases.
Frequent updates to icon fonts like Material Design can break deployments, necessitating manual updates and careful version handling, as highlighted in release notes.
TIconFontsImageList is explicitly recommended only for simple single-form applications, restricting its use in larger, multi-form projects without additional components.
