1. Preface

In the digital design realm, vector graphics are the preferred choice among designers for their ability to scale infinitely without losing fidelity. However, converting bitmap images (such as PNG) into vector graphics has always been a complex and time-consuming process. Now, the Codia AI VectorMagic plugin, utilizing advanced AI technology, offers a new solution for Figma users. It can convert PNG images into SVG format full-color vector graphics, greatly simplifying this process. This article will delve into the technical details and AI capabilities behind this conversion process.

2. Introduction to PNG and SVG Formats

PNG (Portable Network Graphics) is a lossless compression bitmap image format widely used in web design. It supports transparent backgrounds but pixelates when the image is enlarged.

SVG (Scalable Vector Graphics) is an XML-based vector graphic format that describes information such as the shape and color of graphics. SVG graphics can be scaled infinitely without distortion, are small in file size, and are easy to modify and animate.

3. Conversion Process

The conversion process of the Codia AI VectorMagic plugin can be divided into the following steps:

1. Image Preprocessing: First, the plugin preprocesses the input PNG image, including resizing, denoising, and edge enhancement.

2. Feature Extraction: Then, the AI algorithm extracts key features from the image, such as edges, corners, and texture areas. This step uses deep learning technology to recognize and understand the visual elements in the image.

3. Vector Reconstruction: Next, AI reconstructs the vector representation of the image based on the extracted features. This involves converting pixel points into vector graphic elements like Bézier curves. The AI algorithm optimizes the control points of the curves to minimize differences from the original image.

4. Color Preservation: To preserve the original image's colors, the plugin uses color quantization techniques to map pixel colors to a finite set of colors. This helps maintain the visual appearance of the image while reducing the complexity of the vector graphics.

5. Optimization and Simplification: Finally, AI optimizes and simplifies the generated vector graphics to improve performance and editability. This includes removing redundant nodes, merging similar paths, and applying compression algorithms.

4. AI Capabilities

The AI capabilities of the Codia AI VectorMagic plugin are mainly reflected in the following aspects:

1. Image Preprocessing:

   • Denoising: Denoising the PNG image to eliminate random noise that may have been introduced during image capture or transmission.
   • Contrast Enhancement: Enhancing the image's contrast makes edges clearer, facilitating subsequent edge detection.
   • Color Correction: To ensure color accuracy during the conversion process, color correction adjusts color balance and saturation to match the color representation of the SVG format.

2. Shape Recognition and Edge Detection:

   • Deep Learning Models: AI identifies shapes and edges in the image. These models learn to extract target shapes from complex backgrounds through training on a large amount of annotated data.
   • Element Recognition: The plugin uses deep neural networks to recognize and understand visual elements in the image, allowing it to handle complex images and retain important visual features.
   • Feature Extraction: Through multi-level feature extraction, it can identify different levels of image features, from simple edges and textures to complex objects and shapes.
   • Edge Detection Algorithms: Algorithms such as the Sobel operator and Canny edge detection can be used to further accurately determine the edge positions in the image.

3. Color Analysis:

   • Color Quantization: The AI system reduces the number of colors in the image through color quantization, which helps simplify the SVG file and reduce file size. Color quantization typically uses clustering algorithms, such as K-means, to achieve this.
   • Color Space Conversion: Since the SVG format may use different color spaces, it is necessary to convert the color space of the PNG image to an SVG-compatible color space, such as RGB or HSL.

4. Path Generation:

   • Bézier Curve Parameter Calculation: Converting detected edges into smooth paths by calculating the control points and endpoints of Bézier curves.
   • Path Optimization: To reduce the complexity of the SVG file, the AI system optimizes the generated paths, merging similar paths, deleting unnecessary points, and simplifying overly complex curves.

5. SVG Assembly:

   • Adaptive Vectorization: Automatically adjust the parameters of vectorization based on the content and complexity of the image. This allows the plugin to handle various types of images, from simple icons to complex illustrations.
   • Assembling Path Data: Combining optimized path data with color information to generate the structure of the SVG.
   • Adding Features: Adding unique attributes of SVG, such as gradients, filters, and animations, to enrich the final graphic's expressiveness.

6. Performance Optimization:
   AI optimizes and simplifies the generated vector graphics to improve performance and editability. This includes applying compression algorithms and removing unnecessary details while maintaining the visual quality of the image.
