Function iconFromFile

iconFromFile(filePath: string, options?: IconFromFileOptions): Icon
Create an Icon object from a local image file.

Reads the file, converts it to a base64 data URI, and returns an Icon object ready for use in createApp configuration.

Size limit: Files must be under 1MB. For larger images, host them externally and use a URL instead. Consider using SVG for logos (smaller size, scalable).
Parameters
- filePath: string
  Path to the image file (absolute or relative to cwd)
- options: IconFromFileOptions = {}
  Optional icon configuration (sizes, theme, mimeType override)
Returns Icon
Icon object with base64 data URI
Example: Basic usage
```
import { createApp, iconFromFile } from "@mcp-apps-kit/core";

const app = createApp({
  name: "my-app",
  version: "1.0.0",
  icons: [iconFromFile("./assets/icon.png")],
  tools: { ... }
});
```
Example: With options
```
const app = createApp({
  name: "my-app",
  version: "1.0.0",
  icons: [
    iconFromFile("./assets/icon-48.png", { sizes: ["48x48"] }),
    iconFromFile("./assets/icon-dark.png", { theme: "dark" }),
    iconFromFile("./assets/icon.svg", { sizes: ["any"] }),
  ],
  tools: { ... }
});
```
Throws
Error if the file cannot be read, exceeds size limit, or has an unsupported extension
