If my image uses the 3857 projection and contains data for a specific region (e.g., [40, 0, 120, 60] as minX, minY, maxX, maxY), and I am implementing it using a Mapbox GL custom layer, how should the matrix be used in the vertex shader?

If my image uses the 3857 projection and contains data for a specific region (e.g., [40, 0, 120, 60] as minX, minY, maxX, maxY), and I am implementing it using a Mapbox GL custom layer, how should the matrix parameter in the render method be used in the vertex shader?
Thanks！
