如何在itextSharp中使用C#Image对象 [英] How to use a c# Image object in itextSharp

问题描述

有什么解决方案可以将c#图像对象转换为iTextSharp兼容图像，以便在pdf中使用.

Is there any solution to convert a c# Image object to an iTextSharp compatible image to be used inside the pdf.

推荐答案

是.类iTextSharp.text.Image具有一个名为GetInstance()的方法，该方法具有18个重载，其中3个重载接受System.Drawing.Image.

Yes. The class iTextSharp.text.Image has a method called GetInstance() that has 18 overloads, 3 of which accept a System.Drawing.Image.

iTextSharp.text.Image.GetInstance(System.Drawing.Image, iTextSharp.text.BaseColor);

iTextSharp.text.Image.GetInstance(System.Drawing.Image, iTextSharp.text.BaseColor, Bool);

iTextSharp.text.Image.GetInstance(System.Drawing.Image, System.Drawing.Imaging.ImageFormat);

几乎在每种情况下，您都需要第一个参数，而只需将null传递给第二个参数(除非您希望将透明像素强制为某种颜色).

In almost every case you want the first one and you can just pass null for the second parameter (unless you want to force transparent pixels to be a certain color).
