The image export functionality has a few issues:

1. The image format is hardcoded to 'png' in scene.mapService.exportMap('png'), ignoring the user's selection from the dropdown. The format variable should be used instead.
2. There are several @ts-ignore comments and a console.log which should be removed from production/example code.
3. The commented-out line // const dataURL = await scene.exportMap(format) suggests the correct method might be on the scene object itself. Please ensure you are using the correct API.

        const format = formatSelect.value as 'png' | 'jpg';
        const dataURL = await scene.mapService.exportMap(format);

The description "修复一些bug" (fix some bugs) is too generic. For better maintainability and clearer release notes, please provide a more specific summary of the bugs that were fixed in this changeset.

Using setTimeout in a loop to check if a layer is rendered is inefficient and can be unreliable. A better approach is to use the inited event on the layer, which signals that it's ready.

  await new Promise<void>((resolve) => {
    pointLayer.once('inited', () => {
      resolve();
    });
  });

The @ts-ignore comment should be avoided. If Scene.addProtocol is a valid method but lacks type definitions, consider casting Scene to any like (Scene as any).addProtocol(...) for clarity. Even better would be to update the type definitions for Scene to include addProtocol if it's part of the public API.

The logic to infer texture dimensions assumes the texture is always square (width = height = Math.sqrt(...)). This is fragile and will fail if the texture data is not from a square texture, as Math.sqrt could produce a non-integer. Consider adding a check to ensure the calculated width is an integer, or refactoring to have width and height passed in as parameters, similar to the createTexture function.

    // 对于 ArrayBuffer 或其他数据类型，需要提供宽度和高度
    const width = Math.sqrt(data.length / 4); // 假设是RGBA格式，每个像素4个值
    if (!Number.isInteger(width)) {
      console.warn('Texture data is not a square, which may cause rendering issues.');
    }
    const height = width;
    gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, width, height, 0, gl.RGBA, gl.UNSIGNED_BYTE, data);

This console.log statement appears to be for debugging and should be removed from the test case.

There are a couple of issues here:

1. A console.log statement has been added, which should be removed.
2. The error message is in Chinese. For consistency with the rest of the codebase, please use English for error messages.

    if (!renderCanvas) {
      throw new Error('Map has not been initialized yet, unable to export image.');
    }
