How to Convert PDF to Image (JPG or PNG) In C# - Accusoft
3 May 2018 ... Create a command line program in C# that can convert a PDF document into a series of images , one for each page of the document. The program will allow the user to select the start and end pages to convert , and what bitmap file format (JPEG, BMP, GIF, and PNG) to save in.

In both instances, the programmer must either know in advance or determine at run time which result type the expression will return. The XPathExpression.ReturnType property returns a value from the XPathResultType enumeration identifying the result type of an expression. This can be used to determine the right method to use or to which type the result should be cast. We discuss the specifics of the Select, Evaluate, and Matches methods in the following sections.

Querying data in the materialized path solution is simple and elegant. For subtree-related requests, the optimizer can always use a clustered or covering index that you create on the path column. If you create a nonclustered, noncovering index on the path column, the optimizer can still use it if the query is selective enough. Let s review typical requests from a tree. For each request, I ll provide a sample query followed by its output. Return the subtree with a given root:

Convert Scanned PDF into Image - MSDN - Microsoft
How can I write a C# program to open the PDF , even as a byte array, ... iTextSharp is supposed to be able to extract images from within a PDF .

This example only scratches the surface of the power of LINQ . LINQ introduces a very streamlined way to make queries on demand from within your project using the language of your project (Visual Basic, C#, and so forth) . You can use the data returned from the queries in any context . In this case, the example shows using the results of a LINQ query in a GridView .

SELECT REPLICATE(' | ', E.lvl - M.lvl) + E.empname FROM dbo.Employees AS E JOIN dbo.Employees AS M ON M.empid = 3 -- root AND E.path LIKE M.path + '%' ORDER BY E.path; Ina | Aaron | | Gabriel | | Rita | | | Emilia | | | Michael | | | Didi

The Select method takes only XPath expressions that result in node sets and returns an instance of XPathNodeIterator. If the XPath expression argument is invalid or doesn't return a node set, XPathNavigator throws an ArgumentException.

The query joins two instances of Employees. One represents the managers (M) and is ltered by the given root employee. The other represents the employees in the subtree (E). The subtree is identi ed using the following logical expression in the join condition, E.path LIKE M.path + % , which identi es a subordinate if it contains the root s path as a pre x. Indentation is achieved by replicating a string ( | ) as many times as the employee s level within the subtree. The output is sorted by the path of the employee. This query generates the execution plan shown in Figure 12-5.
