将对齐的段落转换为图像
我需要将一段文本转换为图像。将文本转换为图像是没有问题的。我有代码可以做到这一点。但文本必须显示为每行居中的段落。那是个问题！
目前，我可以将文本转换为左对齐段落，因为文本字符串中有回车符。我想它可以用字符串中的空格居中对齐，但很难计算所需的空格。一定有更简单的方法。
我需要的是某种方法将文本格式化为段落，然后将其转换回字符串，并保留空格。对于 ASP.NET Web 应用程序，这需要在 VB.NET 中完成。
有什么想法吗？我可以使该段落以富文本格式对齐，但我不知道是否可以将其转换回字符串，并保留空格。创建 PDF 是另一种可能性。
从文本创建的图像需要为 300 DPI，且背景透明。我使用 Graphics 对象的 DrawString 方法来创建图像。
I need to convert a paragraph of text into an image. Converting the text into an image is no problem. I have the code to do that. But the text must be shown as a paragraph with each line centered. That is a problem!
Currently I can convert the text into a left justified paragraph because there are carriage returns in the text string. I suppose it could be center justified with spaces in the string but it would be hard to calculate the required spaces. There must be an easier way.
What I need is some way to format the text into a paragraph and then convert it back into a string, preserving spaces. This needs to be done in VB.NET for an ASP.NET web application.
Any ideas? I could get the paragraph justified in Rich Text Format but I don't know if it can be converted back into a string, preserving spaces. Creating a PDF is another possibility.
The image created from the text needs to be 300 DPI with a transparent background. I'm using the DrawString method of a Graphics object to create the image.
