Answer 3

For Word documents, you need a solution that can understand and take a picture. You can use TxTextControl or some Word printer driver, such as Easy PDF Creator.

Once you have the PDF file ready, you can use Super Pdf2Image Converter.NET . It is available for both 32 and 64 bit and is very cheap and efficient.

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

For example, here is a sample code for conversion:

 // 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);
