pdf.Compress(compressionOptions);
pdf.SaveAs("compressed.pdf");

Dim renderer As New ChromePdfRenderer()

Dim pdf As PdfDocument = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Main_Page")

' Define and include additional options if needed

compressionOptions.ShrinkImages = True
compressionOptions.CompressImages = True

' Compress images in the PDF
pdf.Compress(compressionOptions)
pdf.SaveAs("compressed.pdf")

異步和多執行緒

支援異步和多執行緒操作，使大規模文件的PDF生成更快，性能更佳。

學習如何：使用多執行緒處理

using IronPdf;

// Instantiate Renderer

var pdf = await renderer.RenderHtmlAsPdfAsync("<h1>Html with CSS and Images</h1>");

// Export to a file or Stream
pdf.SaveAs("async_example.pdf");

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// All IronPdf Rendering methods have Async equivalents
var pdf = await renderer.RenderHtmlAsPdfAsync("<h1>Html with CSS and Images</h1>");

// Export to a file or Stream
pdf.SaveAs("async_example.pdf");

Imports IronPdf

' Instantiate Renderer
Dim renderer = New ChromePdfRenderer()

' All IronPdf Rendering methods have Async equivalents
Dim pdf = Await renderer.RenderHtmlAsPdfAsync("<h1>Html with CSS and Images</h1>")

' Export to a file or Stream
pdf.SaveAs("async_example.pdf")

自訂日誌記錄

建立自訂日誌以跟蹤PDF生成、修改和轉換過程，實現更好的除錯和性能分析。

了解如何：啟用自訂日誌

IronSoftware.Logger.LoggingMode = IronSoftware.Logger.LoggingModes.Custom;
IronSoftware.Logger.CustomLogger = new CustomLoggerClass("logging");

IronSoftware.Logger.LoggingMode = IronSoftware.Logger.LoggingModes.Custom;
IronSoftware.Logger.CustomLogger = new CustomLoggerClass("logging");

IronSoftware.Logger.LoggingMode = IronSoftware.Logger.LoggingModes.Custom
IronSoftware.Logger.CustomLogger = New CustomLoggerClass("logging")
