Design Patterns: Elements of Reusable Object-Oriented Software (Addison-Wesley, 1995), by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, is the cornerstone book on interaction mechanism types. It is very thorough and detailed, including about the meaning and uses of individual mechanism types. It also includes at least one fairly detailed code example for each, in C++ or Smalltalk. The interaction algebra examples in Four can also serve as a quick detailed catalog for the entire book, and each formula is actually a map for the corresponding code example. (There are also other Design Patterns books, by other authors, that have morespecialized interaction mechanism types.) For the most effective reading of Design Patterns, it s helpful to keep in mind that: Its successive sections of an explanation often use differing names for the same entity. Some sections don t note some parameters. Some examples are spread over multiple sections. Each benefits and consequences section doesn t identify which is which. The book just barely predates UML, so its diagrams are not quite standard, but it does explain them inside the back cover. Refactoring: Improving the Design of Existing Code (Addison-Wesley, 1999), by Martin Fowler, addresses sound practices for the design optimization process. It is a pointed cross-check for other areas of designing that provides a very good feeling for the spectrum of class usages. And Modern C++ Design: Generic Programming and Design Patterns Applied (AddisonWesley, 2001), by Andrei Alexandrescu, is the book that introduces the template-based, low-level designing technique. It is intense. convert pdf to jpg using itext in java: Convert PDF to Image in Java : JPG PNG TIFF BMP | PDFTron convert pdf to jpg using itext in java PDF to image using Java - Stack Overflow

The books listed here serve that purpose for Java. All of these are O Reilly books. Each of the in a Nutshell series books is mostly a reference to the standard classes just the declaration of their data items and functions preceded by a brief description of their common usages. While that treatment is beneficial as an introduction only at a high level, it does provide a fairly quick detailed view of the scope of functions that the packages address. pdf to image converter example in java: PDF Conversions in Java | Baeldung convert pdf to jpg using itext in java How to convert Pdf file into image file in java using iText sharp ...

In this tutorial, we will write a standalong Java Class that will convert a JPG file into ... to convert a JPG image to PDF file using Java iText API is provided below; a graphical context to work. We ll talk about contexts more in chapter 13; for now, keep in mind that a graphical context is a destination you re drawing to, like a window, a PDF file, or a printer. On the iPhone and iPad, UIViews automatically create a graphical context as part of their CALayer, which is a Core Animation layer associated with each UIView. You can access this layer by writing a drawRect: method for the UIView (or rather, for a new subclass that you ve created). You usually have to capture a special context variable to do this type of work, but the UIView methods take care of this for you, to keep things simple. Here s how to collage together a few pictures using this method: - (void)drawRect:(CGRect)rect { UIImage *myImage1 = [UIImage imageNamed:@"sproul1.jpg"]; UIImage *myImage2 = [UIImage imageNamed:@"sproul2.jpg"]; UIImage *myImage3 = [UIImage imageNamed:@"sproul3.jpg"]; [myImage1 drawAtPoint:CGPointMake(0,0) blendMode:kCGBlendModeNormal alpha:.5]; [myImage2 drawInRect:CGRectMake(10, 10, 140, 210)]; [myImage3 drawInRect:CGRectMake(170, 240, 140, 210)]; } java pdf to jpg Convert an image to a PDF using iText library for java · GitHub

Note that the drawAtPoint: method gives you access to more complex possibilities, such as blending your pictures (using Photoshop-like options such as color dodge and hard light) and making them partially transparent. Here you re using a normal blend, but only 50 percent transparency (hence the use of the drawAtPoint: method). Using singular draw commands is simpler than going through the effort of creating multiple UIImageView objects. There s still a lot that you can t do until we dive fully into the Core Graphics framework; but for now you have some control, which should be sufficient for most common media needs. If you need more control, skip right ahead to chapter 13. We ve talked a lot about images, and we ve presumed so far that you re loading them from your project s bundle. But what if you want to let a user select photographs That s the topic of the next section. JavaServer Faces (O Reilly, 2004), by Hans Bergsten, is a very thorough and wellthought-out explanation of the module-based approach to browser application development. It also addresses various compatibilities and conflicts with other technologies. JavaServer Pages, Third Edition (O Reilly, 2003), also by Hans Bergsten, is a similar explanation of the technology that JavaServer Faces is an extension of. As such, it includes further details of that technology. The third edition is for JSP 2.0. Java in a Nutshell, Fifth Edition (O Reilly, 2005), by David Flanagan, is dedicated to the more-basic global language functions. Java Foundation Classes in a Nutshell (O Reilly, 1999), also by David Flanagan, covers the functions related to development of user interfaces. Java Enterprise in a Nutshell, Second Edition (O Reilly, 2002), by Jim Farley, William Crawford, and David Flanagan, extends to the functions for servers and very large distributed applications. java pdf to jpg Convert PDF to an Image - iText
