build — slides to PPTX bytes

Positions are inches from the top-left. A widescreen slide is 13.33×7.5.

import { build } from "@nodetool-ai/sandbox-pptxgen";

const bytes = await build({
  title: "Q3 Review",
  author: "NodeTool",
  slides: [
    {
      background: "#0f172a",
      items: [
        { type: "text", x: 0.5, y: 0.4, w: 12, h: 1, text: "Q3 Review", fontSize: 36, color: "#ffffff", bold: true },
        { type: "shape", shape: "rect", x: 0.5, y: 1.6, w: 4, h: 0.15, fill: "#38bdf8" },
        { type: "image", x: 8, y: 2.5, w: 4, h: 3, data: inputs.chart }
      ]
    }
  ]
});
await workspace.writeBytes("q3.pptx", bytes);
