THotPDF.BeginLoadedPageProgressiveRender Method

パラメータ

戻り値

Returns a caller-owned THPDFLoadedPageRenderSession that retains the partial bitmap and render state

使用上の注意

• Keep the loaded THotPDF instance and any explicit token alive until the session is freed
• Call ContinueRender with an elapsed-time budget, an operator-count budget, or both until the session completes or is cancelled
• Bitmap exposes the live partial image and TakeBitmap transfers the terminal image without copying
