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

graph TD
    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]

Font Support

To use custom fonts (especially for Chinese text):

  1. Place your .ttf or .otf font files in the font directory
  2. The fonts will be automatically detected and used for rendering

Known Limitations

  • Maximum 3 image replacements per SVG
  • Maximum 10 text replacements per SVG
  • SVG animations are not supported
  • External images in SVG must be base64 encoded
