  • Watermarking the easy way

    March 01, 2010 | Tags: Morgan, Image Library, C#, Snippet
    This post will show how easy it is to do a bit of watermarking using the open source C# Image Library.

    What we'll do
    Watermarks can appear in many different ways. This sample will show how to create the following in just a couple of lines:

    Step by step

    Preparations
    First of all, head over to http://code.google.com/p/imagelibrary/ and download the latest DLL (or source code if you want to compile it yourself).

    Secondly, you'll need a watermark to apply to your images. Create a PNG image with very transparent layers in both black and white. The one I've created has black texts in a layer of 10% opacity as well as a white outline also with 10% opacity. (Please note that the watermark will be tiled, in other words used x * y times to cover the image you want to mark.)
    This is my watermark.png (applied on a gray background):


    Finally lets do some coding!
     Create a new project and add the C# Image library  you just downloaded (either the DLL or the project). Enter the following lines (in the appropriate place, depending of what type of project you're developing).
    using Kaliko.ImageLibrary;

    //...

    // Open the image you want to watermark
    KalikoImage image = new KalikoImage("c:\\MyImage.jpg");

    // Apply your watermark PNG image
    image.BlitFill("c:\\Watermark.png");

    // Save new marked image as high-quality jpeg
    image.SaveJPG("c:\\Marked.jpg", 99);

    That wasn't so hard, was it? :) The C# Image library is developed to ease common graphical tasks as this.

  • Get correct week number in .NET

    November 20, 2009 | Tags: Morgan, ASP.NET, C#, Snippet
    A nice piece of code submitted by Morgan Johansson for getting the correct week number for your region (in this sample code Sweden ("se-SE"):
    public int GetWeekNo(DateTime date) {
    System.Globalization.CultureInfo cult_info = System.Globalization.CultureInfo.CreateSpecificCulture("se-SE");
    System.Globalization.Calendar cal = cult_info.Calendar;
    int weekNo = cal.GetWeekOfYear(date, cult_info.DateTimeFormat.CalendarWeekRule, cult_info.DateTimeFormat.FirstDayOfWeek);
    return weekNo;
    }
