解決IronPDF中的渲染超時問題

Curtis Chau

Updated: 2025年9月11日

IronPDF的預設渲染超時是60秒。如果渲染過程在此期間未完成，將拋出超時運行時異常。

對於圖像資產較多或需要額外時間渲染的輸入，建議調整RenderDelay時間。這允許資產在產生PDF之前完整地虛擬渲染。若未這樣做，可能會導致PDF文件中缺少資產甚至空白PDF。

要覆蓋預設設定，請在RenderDelay方法中指定延遲時間。

範例

// Create a new instance of ChromePdfRenderOptions
ChromePdfRenderOptions renderOptions = new ChromePdfRenderOptions();

// Increase the timeout for the rendering process to 120 seconds
renderOptions.Timeout = 120; // seconds

// Increase the delay before rendering to ensure all assets are fully loaded
renderOptions.WaitFor.RenderDelay(3000); // milliseconds (3 seconds)

// Create a new instance of ChromePdfRenderOptions
ChromePdfRenderOptions renderOptions = new ChromePdfRenderOptions();

// Increase the timeout for the rendering process to 120 seconds
renderOptions.Timeout = 120; // seconds

// Increase the delay before rendering to ensure all assets are fully loaded
renderOptions.WaitFor.RenderDelay(3000); // milliseconds (3 seconds)

' Create a new instance of ChromePdfRenderOptions
Dim renderOptions As New ChromePdfRenderOptions()

' Increase the timeout for the rendering process to 120 seconds
renderOptions.Timeout = 120 ' seconds

' Increase the delay before rendering to ensure all assets are fully loaded
renderOptions.WaitFor.RenderDelay(3000) ' milliseconds (3 seconds)

' Create a new instance of ChromePdfRenderOptions
Dim renderOptions As New ChromePdfRenderOptions()

' Increase the timeout for the rendering process to 120 seconds
renderOptions.Timeout = 120 ' seconds

' Increase the delay before rendering to ensure all assets are fully loaded
renderOptions.WaitFor.RenderDelay(3000) ' milliseconds (3 seconds)
