Note that the Doom engine uses a 768-color palette (256 colors for each one of red, green, and blue). The palette is read from the game file, along with a gamma table (used to apply a brightness factor to each color). With this information, the palette is filled and kept in memory for later use. The final change to i_video.c is the function that does the actual rendering, I_FinishUpdate (see Listing 7-24). This function uses the width and height of the screen to create an array of pixels (each one representing an Android packed ARGB color). It then loops through the array and uses the byte value from the screen buffer to look up the color from the palette: byte b = screens[0].data[i]; // Video buffer byte XColor color = colours[b]; // Palette color for that byte It then constructs a 32-bit pixel using the RGB values of color: pixels[i] = (0xFF << 24) | (color.red << 16) | (color.green << 8) | color.blue Note that 0xFF << 24 represents the alpha (opacity) value of the pixel fully visible in this case. how to upload only pdf file in asp.net c# PDF Viewer ASP .

This function is responsible for building a query that returns data from the requested page It s an overloaded method, so you can call it with or without any parameters GetPagedQuery uses two parameters named currentPage and itemsPerPage, which help determine which page of data to return You can specify this by calling GetPagedQuery and passing the current page and items per page in as parameters, or you can set the CurrentPage and ItemsPerPage properties on the SqlQuery object and call GetPagedQuery without any parameters The parameterless version of the function simply calls the parameterized version and passes in the property values The first couple of lines in the method ensure that there are valid values for the currentPage and itemsPerPage parameters If either one of the values is invalid, it s assigned a valid value You can also throw an exception here if you want to. c# pdf viewer free Filling PDF Form using iText PDF Library - CodeProject

Using iTextSharp's PdfReader class to extract the deflated content of every page, I use a simple function ExtractTextFromPDFBytes to extract the text contents ... GetPagedQuery then calls BuildQuery(False,True), which tells BuildQuery to return a paged query and stores that paged query in the PagedQuery variable If the requested page is the first page, then no more work needs to be done because the TOP value returns the correct amount of data for the first page On subsequent pages, however, a bit more work needs to be done to hack off the extraneous data returned at the beginning of the result set To get rid of that data, GetPagedQuery wraps the query in PagedQuery in another SELECT statement that operates on the data returned by PagedQuery Remember, the data in PagedQuery contains a column named RowNum that identifies the rows returned by the query in sequential order Also remember that the BuildQuery method limits the amount of data returned for a paged query using the TOP keyword. free pdf viewer c# .net Export Crystal Reports to PDF in C# - C# Corner

So, to get the right data, the second SELECT statement only selects rows whose RowNum value is higher than _ItemsPerPage * (_CurrentPage - 1) Here s an example Say you are trying to get data for page 6 of a query, and you are showing 10 items per page This means that you are trying to display row numbers 51 60 BuildQuery ensures that only 60 rows of data come back, so you only have to worry about getting rid of the extraneous data before row 51 So, the outer SELECT statement created by GetPagedQuery selects rows whose RowNum values are greater than 50 You acquire this value using the equation _ItemsPerPage * (_CurrentPage - 1) = 10 * (6-1) = 10 * 5 = 50 And that s how the SqlQuery class builds normal and paged queries Next, you ll learn how to use the SqlQuery class in code.. Log4j supports logger hierarchy. The loggers are organized in a parent-child relationship. For example, a logger named com.foo is the parent logger of the logger com.foo.bar. In the logger hierarchy, the child logger inherits the properties and the logger components from its immediate parent. In short, this means that all the logging events captured by the child logger will be processed by the child logger itself and also by its parent logger. This may also mean that logging messages will appear twice if both the child and parent logger use the same logging destinations, which may be undesirable. Of course, in log4j, we can turn off the use of the parent logger in the hierarchy. You can do so via setAdditivity(false); or via the configuration file, add this line: log4j.logger.[logger name].additivity=false c# open pdf adobe reader How to Open PDF Files in Web Brower Using ASP.NET - C# Corner
