Answer 1

(Disclaimer I worked on this component at Software Siglo XXI)

If you don't want to mess with Ghostscript API and need a quick working solution to convert PDF documents to raster images (PNG, JPG, ...), you could use Super Pdf2Image Converter .NET. It's available for both 32 and 64 bit and is very cheap and effective.

You can take a look here: http://softwaresigloxxi.com/SuperPdf2ImageConverter.html

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);
