definition order issue
The DCI Image node was returning None because the
_translate_to_original function was being called before it was
defined, causing a NameError that prevented the node from
executing properly.
Root cause:
- _translate_to_original function was called on line 119 for
palette type conversion
- Function definition was located on line 158, after the call
- This caused a NameError during execution, resulting in None output
Fix:
1. Moved _translate_to_original function definition to before
its first usage (before palette type conversion)
2. Removed duplicate function definition that appeared later
in the code
3. Maintained all existing functionality and translation logic
Testing:
- Created comprehensive test script to verify fix
- Tested with various parameter combinations
- Confirmed proper DCI image data generation
- Verified all required fields are present in output
- Validated image content generation and metadata
Result:
- DCI Image node now properly returns DCI_IMAGE_DATA tuple
- All translation functionality works correctly
- Generated proper DCI paths and image content
- Node executes without errors in all test scenarios
修复DCI图像节点因函数定义顺序问题返回None
DCI图像节点返回None是因为_translate_to_original函数在定义
之前被调用，导致NameError阻止节点正常执行。
问题根源：
- _translate_to_original函数在第119行被调用用于调色板类型转换
- 函数定义位于第158行，在调用之后
- 这导致执行时出现NameError，结果返回None
修复方案：
1. 将_translate_to_original函数定义移到首次使用之前
2. 删除代码中后面出现的重复函数定义
3. 保持所有现有功能和翻译逻辑
测试验证：
- 创建全面的测试脚本验证修复
- 测试各种参数组合
- 确认正确的DCI图像数据生成
- 验证输出中包含所有必需字段
- 验证图像内容生成和元数据
修复结果：
- DCI图像节点现在正确返回DCI_IMAGE_DATA元组
- 所有翻译功能正常工作
- 生成正确的DCI路径和图像内容
- 节点在所有测试场景中无错误执行
