调研方向

首先运行提供的模块脚本并检查 lib/index.js,尤其是 mapToNewConfig、setOptions、initExport 和 startExport。将生成的图像与提供的图表选项进行比较,并跟踪导出过程中注释的处理方式。导出的图像包含两个注释即表示完成。

由索引模型根据 Issue 内容生成。

Reproduction steps

### here is js code used

import { writeFileSync } from 'fs';
import exporter from '../../lib/index.js';
// Export settings with the old options structure (PhantomJS)
// Will be mapped appropriately to the new structure with the mapToNewConfig utility
const exportSettings = {
  type: 'png',
  constr: 'chart',
  outfile: './samples/module/options_phantom.jpeg',
  logLevel: 4,
  scale: 1,
  workers: 1,
  options: {
    chart: {
      type: "column",
      backgroundColor: "#FFFFFF",
    },
    title: {
      text: "Monthly Revenue",
    },
    xAxis: {

            text: "Year-End Peak",
          },
        ],
      },
    ],
  }
};
const start = async () => {
  try {
    // Map to fit the new options structure
    const mappedOptions = exporter.mapToNewConfig(exportSettings);
    // Set the new options
    const options = exporter.setOptions(mappedOptions);
    // Init a pool for one export
    await exporter.initExport(options);
    // Perform an export
    await exporter.startExport(options, async (error, info) => {
      // Exit process and display error
      if (error) {
        throw error;
      }
      const { outfile, type } = info.options.export;
      // Save the base64 from a buffer to a correct image file
      writeFileSync(
        outfile,
        type !== 'svg' ? Buffer.from(info.result, 'base64') : info.result
      );
      // Kill the pool
      await exporter.killPool();
    });
  } catch (error) {
    // Log the error with stack
    exporter.logWithStack(1, error);
    // Gracefully shut down the process
    await exporter.shutdownCleanUp(1);
  }
};
start();
