c# itextsharp add image to pdf

Adding an image to a PDF using iTextSharp and scale it properly ...
I solved it using the following: foreach (var image in images) { iTextSharp.text.Image pic = iTextSharp.text.Image.GetInstance(image, System.

When you think about it, it s pretty obvious that for a person to perceive an interactive product as considerate and smart, that product must have some knowledge about the person and be capable of learning from their behavior. Looking through the characteristics of considerate products presented earlier reinforces this fact: For a product to be truly helpful and considerate it must remember important things about the people interacting with it. Quite often, software is difficult to use because it operates according to rational, logical assumptions that, unfortunately, are very wrong. Programmers and designers often assume that the behavior of users is random and unpredictable, and that users must be continually interrogated to determine the proper course of

Required input validation: Checks to make sure some value was put in to a specific control, without making a judgment about whether it is an appropriate value at the UI level Input range validation: Checks the input value against a range of acceptable values Input comparison validation: Compares the values in two or more input controls and ensures that they all have the same value Input pattern validation: Checks the input to ensure it complies with some textual pattern, such as a Social Security Number or phone number having dashes in the right place, a string having the appropriate case or length, and so on You can easily perform that kind of checking using the power of regular expressions

action Although human behavior certainly isn t deterministic like that of a digital computer, it is rarely random, and asking silly questions is predictably frustrating for users If your application, Web site, or device could predict what a user is going to do next, couldn t it provide a better interaction If your application could know which selections the user will make in a particular dialog box or form, couldn t that part of the interface be skipped Wouldn t you consider advance knowledge of what actions your users take to be an awesome secret weapon of interface design Well, you can predict what your users will do.

The amount of radiation energy per unit frequency interval and per unit volume is w(v) = N(v)EIV. Hence,

81rhv 3 (J.1.E )3/2 w(v) = ehv/KT _ 1

You can build a sixth sense into your application that will tell it with uncanny accuracy exactly what the user will do next! All those billions of wasted processor cycles can be put to great use: All you need to do is give your interface a memory When we use the term memory in this context, we don t mean RAM, but rather a facility for tracking and responding to user actions over multiple sessions If your application simply remembers what the user did the last several times (and how), it can use that as a guide to how it should behave the next time If we enable our products with an awareness of user behavior, a memory, and the flexibility to present information and functionality based upon previous user actions, we can realize great advantages in user efficiency and satisfaction.

To compute radiation intensity, consider a slab of area A and infinitesimal thickness d. Such a volume would contain radiation energy
