HoneyGUI is a graphical user interface display solution developed by Realtek. It supports multiple font display engines, enabling users to implement diverse and customizable font display solutions in their devices and applications, applicable to various smart wearable devices and IoT devices.

1. Introduction

The font display solution utilizes the text controls and font rendering engine in HoneyGUI to provide a rich set of features:

 Offers 15 text layout modes to meet diverse layout needs.

A schematic of all layout modes is shown below.

Layout Modes Schematic

The actual rendering effects of text under several layout modes are as follows:

Single-line layout (LEFT/CENTER/RIGHT) display effects

Multi-line layout (MULTI_LEFT/MULTI_CENTER/MULTI_RIGHT) and word wrap display effects

Chinese and vertical layout (VERTICAL_LEFT) display effects

 Supports text scrolling effects in four directions to enhance visual dynamism.

Scrolling text (SCROLL_X/SCROLL_Y) effects

 Supports custom animation effects, adding creative elements to text display.

Animated text effects

 Compatible with a variety of EMOJI symbols, enriching forms of expression.

Emoji text display effects

 Supports text rotation, translation, scaling, perspective, and transparency effects.

Multi-line text transition display effects

 Supports multi-level anti-aliasing to ensure high quality and clarity of text display.

Utilizes alpha channel anti-aliasing technology, representing pixel opacity with 1/2/4/8-bit data to smooth glyph edges and reduce aliasing effects, providing clear and smooth text display. The image shows rendering effects of four anti-aliasing levels, from top to bottom: 1-bit (2-level), 2-bit (4-level), 4-bit (16-level), and 8-bit (256-level) anti-aliasing.

Multi-level Anti-aliasing Display Effects

In addition to providing rich text display features, HoneyGUI excels technically, showcasing highlights in compatibility, flexibility, and development support.

 Compatible with UTF-8, UTF-16, and UTF-32 standard Unicode encodings.

 Supports diverse rendering with multiple languages, fonts, and sizes.

 Supports 32-bit true color, presenting more vivid color performance.

 Compatible with standard TTF font files and custom font library files.

 Provides extensive technical documentation and a modular coding structure, facilitating the porting of custom font libraries.

2. Font Solutions

HoneyGUI offers comprehensive solutions for different font rendering methods, including bitmap font solutions and vector font solutions, to meet various application needs. Both solutions support all the features mentioned above.

 Bitmap Font Solutions:

Realtek has developed a complete bitmap font generation tool that allows customization of character indexing within any range, and supports multi-level anti-aliasing and compression functions. This ensures high-quality text display while effectively reducing file size. Leveraging HoneyGUI's text controls, bitmap fonts can be flexibly inserted into any interface, achieving various custom display effects with extremely high rendering speed. The font library solution offers extensive technical and porting documentation, making it easy for users to port font library code when they need to use custom font library solutions.

 Vector Font Solutions:

Vector font solutions provide higher display quality, with accompanying font tools capable of cropping and encoding vector fonts, ensuring the precision of vector information while reducing file size. The vector font engine within HoneyGUI has undergone deep algorithm optimization for the Realtek platform, ensuring both quality and efficiency. Additionally, vector fonts support a complete image rendering matrix, enabling diverse image transformation effects, allowing text to achieve a special presentation akin to artistic fonts.
