问题 Hi I have been using itextSharp for all pdf related projects in dot.net. I came across a requirement where I need to convert PDF pages to images. I could not find any sample of such a thing. I found that another tool ghostscript is able to do it the problem with that is I am on a shared hosting & I don't think ghostscript will run on server as in my local machine I had to manually copy ghost script dlls to system32 folder which is not possible in a shared hosting. 回答1: Ok I searched all over
