Abcpdf 可复制/可选择文本
我正在使用 websupergoos abcpdf 通过 addimageurl 将 html 页面转换为 pdf。
效果很好,但生成的 pdf 不允许用户选择文本和复制。一切都是一个“图像”。
可以这样做吗?要使用哪些设置?
这是我当前的代码。评论的“扁平化”似乎没有做任何相关的事情。 HttpStream 只是将 pdf 作为文档转发给用户。
var doc = new Doc();
doc.HtmlOptions.UseScript = true;
doc.Units = "mm";
doc.MediaBox.String = "0 0 210 297";
doc.Rect.String = doc.MediaBox.String;
doc.Rect.Inset(10.0, 10.0);
doc.SetInfo(0, "License", abcpdfkey);
doc.HtmlOptions.UseScript = true;
doc.HtmlOptions.AddMovies = true;
doc.HtmlOptions.RetryCount = 0;
doc.HtmlOptions.ContentCount = 1;
doc.Page = doc.AddPage();
for (int i = doc.AddImageUrl(url); doc.Chainable(i); i = doc.AddImageToChain(i))
{
doc.Page = doc.AddPage();
}
int pageCount = doc.PageCount;
for (int j = 1; j <= pageCount; j++)
{
doc.PageNumber = j;
// doc.Flatten();
}
this.HttpStream(doc.GetData(), filename);
i'm using websupergoos abcpdf to convert html pages to pdf via addimageurl.
Works great, but the resulting pdf does not allow the user to select text and copy. All is one 'image'.
Is it possible to do this? Which are the settings to use?
This is my current code. The commented "flatten" does not seem to do anything relevant. The HttpStream simply forewards the pdf to users as a doc.
var doc = new Doc();
doc.HtmlOptions.UseScript = true;
doc.Units = "mm";
doc.MediaBox.String = "0 0 210 297";
doc.Rect.String = doc.MediaBox.String;
doc.Rect.Inset(10.0, 10.0);
doc.SetInfo(0, "License", abcpdfkey);
doc.HtmlOptions.UseScript = true;
doc.HtmlOptions.AddMovies = true;
doc.HtmlOptions.RetryCount = 0;
doc.HtmlOptions.ContentCount = 1;
doc.Page = doc.AddPage();
for (int i = doc.AddImageUrl(url); doc.Chainable(i); i = doc.AddImageToChain(i))
{
doc.Page = doc.AddPage();
}
int pageCount = doc.PageCount;
for (int j = 1; j <= pageCount; j++)
{
doc.PageNumber = j;
// doc.Flatten();
}
this.HttpStream(doc.GetData(), filename);

在将 PDF 发送到 HTTP 流之前,您可以设置加密属性
CanCopy 属性设置用户是否可以从 PDF 复制文本
要设置它,请添加以下代码:
您可能还需要设置 doc.Encryption.CanExtract
Before sending the PDF to the HTTP stream, you can set the encryption properties
The CanCopy Property sets if the user can copy text from the PDF
To set it add the following code:
You may need to set doc.Encryption.CanExtract as well
