例如，这里有一个样品code转换：

For instance, here's a sample code for converting:

// Instantiate the component
Pdf2ImageConverter p2i = new Pdf2ImageConverter(pdfPath);

// Get page count of a PDF file
int pages = p2i.GetPageCount();

// Get size of any page
int width, height;
p2i.GetPageSize(1, out width, out height);

// Convert any page of PDF to image file (preserving aspect ratio)
p2i.GetImage(outputImagePath, pageNumber, resolution, imageFormat);

// Or... convert any page of PDF to image (returns bitmap object)
Bitmap bm = p2i.GetImage(pageNumber, resolution, width, height, imageFormat);
