如何将图像（以字节为单位）转换为没有物理路径的PDF [英] How to convert image (in bytes) to PDF without physical path

问题描述

我需要将图像文件（转换为字节）转换为pdf文件，而不需要物理路径。我正在使用ABCPDF。请帮忙。下面是我当前的代码，但它需要有一个物理路径转换为PDF。



string image = @C：\ Users\osmtft\Desktop\Teemee\NSO_ReportOfBirth2013_h800.jpg;

param.ImageData = System.IO.File.ReadAllBytes（image）;



MemoryStream ms2 = new MemoryStream（）;

ms2.Write （param.ImageData，0，param.ImageData.Length）;



XImage theImg = new XImage（）;

theImg.SetData（ param.ImageData）;



Doc theDoc = new Doc（）;

theDoc.MediaBox.String = theImg.BoundingBox.String;

theDoc.Rect.String = theDoc.MediaBox.String;

theDoc.AddImageObject（theImg，false）;

theDoc.Save（ms2） ;



Doc theDoc2 = new Doc（）;

theDoc2.Read（theDoc.GetData（））;

// theDoc2.Save（newFilename）;



imageBytes = theDoc2.GetData（）;



Doc theDoc3 = new Doc（）;

theDoc3.Read（theDoc.GetData（））;

theDoc3.Save（@C：\ Users \ osmtft \ Desktop\Teemee \helloXXX.pdf）;



我尝试过：



我试过在ABCPDF文档中搜索任何方法。但无济于事。

I am required to convert image files (converted to bytes) into a pdf file without having a physical path. I am using ABCPDF. Please help. Below is my current code but it requires to have a physical path to be converted into PDF.

string image = @"C:\Users\osmtft\Desktop\Teemee\NSO_ReportOfBirth2013_h800.jpg";
param.ImageData = System.IO.File.ReadAllBytes(image);

MemoryStream ms2 = new MemoryStream();
ms2.Write(param.ImageData, 0, param.ImageData.Length);

XImage theImg = new XImage();
theImg.SetData(param.ImageData);

Doc theDoc = new Doc();
theDoc.MediaBox.String = theImg.BoundingBox.String;
theDoc.Rect.String = theDoc.MediaBox.String;
theDoc.AddImageObject(theImg, false);
theDoc.Save(ms2);

Doc theDoc2 = new Doc();
theDoc2.Read(theDoc.GetData());
//theDoc2.Save(newFilename);

imageBytes = theDoc2.GetData();

Doc theDoc3 = new Doc();
theDoc3.Read(theDoc.GetData());
theDoc3.Save(@"C:\Users\osmtft\Desktop\Teemee\helloXXX.pdf");

What I have tried:

I have tried searching for any methods in the ABCPDF documentation. But to no avail.

推荐答案

这取决于以后生成的PDF的使用位置。



如果您不想保存PDF，请使用 Doc GetData函数。将文档保存到内存。 ABCpdf.NET PDF库。 [ ^ ]。返回的字节数组包含原始PDF数据（与写入文件时相同的数据）。在您的应用程序中使用它，例如使用剪贴板将其传递给其他应用程序，或通过网络发送。

It depends on where the generated PDF should be used later.

If you don't want to save the PDF, use the Doc GetData Function. Saves a document to memory. ABCpdf.NET PDF Library.[^]. The returned byte array contains the raw PDF data (same data as when written to a file). Use it within your application, pass it to other applications using the clipboard for example, or send it via network.
