將網頁和HTML轉換為PDF時 GrabzIt的ASP.NET API 提供以下有助於幫助的功能 integrate GrabzIt into您的系統盡可能地容易。 但是,在開始之前,請記住 URLToPDF, HTMLToPDF or FileToPDF 方法 Save or SaveTo 必須調用方法來獲取PDF屏幕截圖。
PDF屏幕截圖將捕獲整個網頁,並將創建與原始網頁相同長度的PDF文檔。 只需一個參數即可轉換網頁 intpdf文檔或 將HTML轉換為PDF 如下圖所示。
grabzIt.URLToPDF("https://www.tesla.com"); //Then call the Save or SaveTo method
grabzIt.HTMLToPDF("<html><body><h1>Hello World!</h1></body></html>"); //Then call the Save or SaveTo method
grabzIt.FileToPDF("example.html"); //Then call the Save or SaveTo method
您可以將自定義標識符傳遞給 PDF 方法,如下所示,此值然後返回到您的GrabzIt ASP.NET處理程序。 例如,該自定義標識符可以是數據庫標識符,從而允許將屏幕截圖與特定數據庫記錄相關聯。
GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret"); PDFOptions options = new PDFOptions(); options.CustomId = "123456"; grabzIt.URLToPDF("https://www.tesla.com", options); //Then call the Save method grabzIt.Save("http://www.example.com/Home/Handler");
GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret"); PDFOptions options = new PDFOptions(); options.CustomId = "123456"; grabzIt.HTMLToPDF("<html><body><h1>Hello World!</h1></body></html>", options); //Then call the Save method grabzIt.Save("http://www.example.com/Home/Handler");
GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret"); PDFOptions options = new PDFOptions(); options.CustomId = "123456"; grabzIt.FileToPDF("example.html", options); //Then call the Save method grabzIt.Save("http://www.example.com/Home/Handler");
創建PDF屏幕截圖時,您可以聲明要應用特定的 模板 到生成的PDF。 該模板必須預先創建,並將定義頁眉和頁腳的內容以及任何特殊變量。 在下面的示例代碼中,用戶正在應用PDF模板“我的模板”。
如果頁眉或頁腳分別沒有足夠大的頂部或底部邊距,則它將不會出現在PDF中。 在下面的示例中,我們將頂部和底部邊距設置為20以提供足夠的空間。
GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret"); PDFOptions options = new PDFOptions(); options.MarginTop = 20; options.MarginBottom = 20; options.TemplateId = "my template"; grabzIt.URLToPDF("https://www.tesla.com", options); //Then call the Save or SaveTo method grabzIt.SaveTo("result.pdf");
GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret"); PDFOptions options = new PDFOptions(); options.MarginTop = 20; options.MarginBottom = 20; options.TemplateId = "my template"; grabzIt.HTMLToPDF("<html><body><h1>Hello World!</h1></body></html>", options); //Then call the Save or SaveTo method grabzIt.SaveTo("result.pdf");
GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret"); PDFOptions options = new PDFOptions(); options.MarginTop = 20; options.MarginBottom = 20; options.TemplateId = "my template"; grabzIt.FileToPDF("example.html", options); //Then call the Save or SaveTo method grabzIt.SaveTo("result.pdf");
如果只想直接轉換div或span等HTML元素 int您可以使用GrabzIt的ASP.NET庫獲得PDF文檔。 您必須通過 CSS選擇器 您希望轉換為HTML元素的 TargetElement
參數。
... <span id="Article"> <p>This is the content I am interested in.</p> <img src="myimage.jpg"> </span> ...
在此示例中,我們希望捕獲跨度中ID為的所有內容 Article
,因此我們將其傳遞給GrabzIt,如下所示。
GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret"); PDFOptions options = new PDFOptions(); options.TargetElement = "#Article"; grabzIt.URLToPDF("http://www.bbc.co.uk/news", options); //Then call the Save or SaveTo method grabzIt.SaveTo("result.pdf");
