Usage

SVG Requirements

Your SVG file should:

1. Have text elements with id attributes like text1, text2, etc., for text replacement
2. Have <image> elements for image replacement
3. Use UTF-8 encoding (especially important for Chinese text)

Example SVG structure:

<svg xmlns="http://www.w3.org/2000/svg" width="800" height="600">
    <text id="text1">Replaceable Text 1</text>
    <text id="text2">替换文本2</text>
    <image x="10" y="10" width="200" height="200" />
</svg>

Nodes

The extension provides two main nodes:

1. SVG Uploader

   • Allows SVG file upload
   • Provides real-time canvas preview
   • Outputs SVG content to SVG Editor

2. SVG Editor

   • Accepts SVG file input from SVG Uploader
   • Has optional inputs for 3 images and 10 text replacements
   • Outputs the final PNG image

Workflow Example

1. Add SVG Uploader node
2. Add SVG Editor node
3. Connect SVG Uploader's output to SVG Editor's input
4. Upload your SVG file using the SVG Uploader
5. Connect your images to SVG Editor's image inputs (optional)
6. Input text replacements in SVG Editor (optional)
7. Run the workflow to get your final image

Example Workflow

    A[SVG Uploader] -->|SVG File| B[SVG Editor]
    C[Image 1] -->|Optional| B
    D[Image 2] -->|Optional| B
    E[Image 3] -->|Optional| B
    B -->|Final Image| F[Output]

Loading

Font Support
