The ColorGram class itself is nothing more than a data structure. I have constructed it such that the combination of any target ColorGram is the function of all the colors in this form: x * red + y * green + z * blue + c, where red, green, and blue are the colors of a pixel, and x, y, z, and c are the values of the ColorGram. The function isMatch() just checks the current pixel color to see if it s in the range of the ColorGram s minimum and maximum values. When it is, it returns true. The very last method of the class is clone(). Here I m creating an exact copy of the ColorGram. Later in this section, I ll continuously modify and optimize a ColorGram object, but right now I just want to optimize the value of the ColorGram, so by cloning it I can get an exact copy without making changes to its reference. See Example 6-20. Example 6-20.

If you think about how you interact with objects in real life, you often receive messages in response to an event that has occurred. For example, when the sandwich vendor comes into the building, a message is issued over the intercom informing employees that the event has occurred. This type of messaging is referred to as broadcast messaging. The server issues the message, and the clients decide to ignore or respond to the message. Another way this event message could be issued is by the receptionist issuing an e-mail to interested employees when the sandwich vendor shows up. In this case, the interested employees would subscribe to receive the event message with the receptionist. This type of messaging is often referred to as subscription-based messaging. Applications built with the .NET Framework are object-oriented, event-driven programs. If you trace the client/server processing chains that occur in your applications, you can identify the event that kicked off the processing. In the case of Windows applications, the user interacting with a GUI usually initiates the event. For example, a user might initiate the process of saving data to a database by clicking a button. Classes in applications can also initiate events. A security class could broadcast an event message when an invalid login is detected. You can also subscribe to external events. You could create a web service that would issue an event notification when a change occurs in the stock market. You could write an application that subscribes to the service and responds to the event notification. private int getColor(Color c, int index) { int out = (int) (c.getRed() * colorGram[index] + c.getGreen() * colorGram[index + 1] + c.getBlue() * colorGram[index + 2] + colorGram[index + 3]); extract data from pdf c# Fill in PDF Form Fields Using the Open Source iTextSharp DLL
