THotPDF.OpenLoadedStreamSourceSlice Method

Opens an independent read-only view over the original encoded bytes of an unfiltered loaded stream without materialising the stream

パラメータ

戻り値

Returns True when the stream is unfiltered, source-backed, and a slice was opened

使用上の注意

• The loaded stream must not have a Filter entry because the slice exposes encoded source bytes
• The returned stream owns its file handle and remains valid independently of later lazy-stream materialisation
• Pass the returned slice to HPDFTransferStream to write directly from its mapped file windows without an intermediate byte buffer
• The caller must free the returned stream
