THotPDF.ResolveLoadedStream Method
将给定的 PDF 对象解析为流对象，自动跟踪间接引用并返回最终的 THPDFStreamObject，适用于访问已加载文档中的内容流或嵌入式资源
Declaration
function ResolveLoadedStream(Obj: THPDFObject): THPDFStreamObject;Unit
HPDFDoc
Parameters
| Name | Purpose |
|---|---|
Obj | The PDF object to be parsed, which can be a direct stream object or an indirect reference to a stream |
Return value
若解析成功，返回对应的 THPDFStreamObject；若传入对象不是流类型或解析失败，则返回 nil
Usage notes
- 传入对象若为间接引用，方法会自动追踪引用链直至找到流对象，无需调用方手动解引用
- 返回值为
nil时，说明目标对象并非流类型，调用前应通过类型检查确认对象类别 - The returned stream object reference is managed by the document, and the caller must not free it; the reference becomes immediately invalid after the document is closed
