A while ago I needed to store some images within a database as part of a project. As a 2nd task I also wanted to create thumnails of the stored image data at varying sizes for an ASP .NET application that was part of my overall project. This article will demonstrate how to store and retrieve image data from a SQL database, and shall also demonstrate how to create thumnail images of this SQL database stored image data.... |

In ‘ MAC-UI Suite ' project (a rich library of more than 60 UI controls with MAC style for .NET), we think about a 3D button that is similar to or even nicer than button of MAC. We may think about 2 ways:
(A) Draw the button by Code.
(B) Using a Picture.
The way (A) has 2 limitations:
- Slower: because we have to draw the button each time of Painting. It's very hard with a complex drawing.
- Difficult to be a Nice Button: as you know, this is not easy even drawing by hand with Pho... |

The HTML Report Engine is a .NET class library which helps in generating well formatted HTML reports. It can take any DataSet as its report source. Reports can have sectional data contents and bar charts.
Crystal Reports is a reporting tool that comes along with VS.NET, but designing and deploying a Crystal Reports report in your application is a bit complex. Though this HTML report engine utility has only limited number of features, it can produce awesome reports with no complex designing an... |

Binary images are images whose pixels have only two possible intensity values. They are normally displayed as black and white. Numerically, the two values are often 0 for black, and either 1 or 255 for white. Binary images are often produced by thresholding a grayscale or color image, in order to separate an object in the image from the background. The color of the object (usually white) is referred to as the foreground color. The rest (usually black) is referred to as the background color. Howe... |

The histogram in the context of image processing is the operation by which the occurrences of each intensity value in the image is shown. Normally, the histogram is a graph showing the number of pixels in an image at each different intensity value found in that image. For an 8-bit grayscale image there are 256 different possible intensities, and so the histogram will graphically display 256 numbers showing the distribution of pixels amongst those grayscale values.... |

The Gaussian smoothing operator is a 2-D convolution operator that is used to `blur' images and remove detail and noise. In this sense it is similar to the mean filter, but it uses a different kernel that represents the shape of a Gaussian (`bell-shaped') hump. This kernel has some special properties which are detailed below.... |

This is my second article that I have written for CodeProject, so I hope some of you find it useful or at least fun. One day, my daughter asked me if we could get Yahtzee for the computer. I thought instead of buying something, why not write it. She has beta tested it quite well, so hopefully most of the bugs have been ironed out in the process. This has took me a while to write, and if you want to see the history of how I got to where the program is now, you can see this on my website. This is ... |

The System.Drawing namespace, which contains types that help you with drawing, plays an important role in Windows programming. You need its members to draw a custom control user interface and for sending text and graphics to a printer. Even when you are only using standard controls on your form, you have used some of its members, probably without realizing it. Understanding the System.Drawing namespace enables you to write better -- and probably faster -- code. Here is a 10-minute crash course t... |

I recently returned from doing voluntary work in East Africa [^], a trip which should have been for a year but which was sadly curtailed after six months by a rather nasty poisonous spider bite. As a result I found myself back in the UK with a large hole in my leg, a stack of photographs and a good deal of time on my hands, so I sat down and wrote Simple Slide Show [^], which is a no-frills slide-show script and display utility offered as “charityware” – donations are invited to Project African ... |

It can detect human emotion from image. First it take an image, then by skin color segmentation it detect human skin color then it detect human face. Then it separate the eyes & lip from the face. Then it draw bezier curve for eyes & lips. Then it compare the bezier curve of eyes and lips to the bezier curves of eyes & lips that are stored in the data base. Then it find the nearest bezier curse from the data base & give that data base stored bezier curve emotion as this image emotion.... |

Sooner or later, you will find the need of handling image in your code, especially when you're working with a database. So in this article, I share with you some useful methods that I find myself using frequently. They include: saving image in a folder, getting thumbnail from the original image, converting image to binary for saving in database, and converting binary data back to image.... |

With the release of the GDI+ API, Microsoft significantly increased the power and flexibility of its graphics API, while at the same time increasing the complexity and surface-area of an already obfuscated GDI API. Fortunately, the .NET Framework provides the System.Drawing namespace hierarchy, wrapping much of the GDI+ API in a (somewhat) manageable facade. Unfortunately, much complexity remains, and consequently many simple image manipulation tasks, such as resizing a bitmap, cropping a regio... |

Hello readers. As we all know, enough said about Design Patterns till now, my intent while writing this article was clear from very start. This article is not going to add another set of ‘black & white’ few MBs of digital text in the huge pile of Design Patterns material already available on the Internet. By saying this, be positive while criticizing me :-)... |

There are two classes and an xml file that are key to each new menu you want. The two classes are Menu.cs and MenuItem.cs. To use the classes you must first create a menu xml file. To create a menu you must create a folder in the Content part of your game project called Menus. Within that create an xml file with the following structure:... |

If you’ve been working long enough in application development like me I’m sure your aware of the benefits of incorporating a good logging mechanism within your application.
Recently I was designing an SOA based enterprise platform. There were a number of services and applications that required some serious logging and honestly I wouldn't have given it much thought and just included some third party component such as log4net or Microsoft Enterprise Application Logging Block that would lo... |

A graphics adapter is a video card that fits into the video slot or interface on a computer motherboard. Video interfaces have evolved over the years, most recently from Advanced Graphics Port (AGP) and all its flavors, to Peripheral Component Interconnect Express, or PCI Express (PCIe). The newer interface allows for faster rendering of images to meet standards that are becoming increasingly demanding.... |
