The cut pieces can then be assembled into a complete poster by gluing the edges together. PosteRazor also takes a Raster image as an input file and cuts it into pieces that can be printed out using a standard sized printer. Poster lovers can check out a very early MakeUseOf HowTo: Free & Huge Custom Poster For Your Wall article that shows how to print out sections of a large image on standard size paper, and assemble it all as a huge poster. PosteRazor is open source and a really small download at 484KB. All that you need is an idea, the PosteRazor freeware and a standard color printer. PosteRazor is a free software that easily helps you make your own posters at home. The ink and paper costs are there but the software does the poster personalization. We didn't have the tools for the job that could help us make our own posters. But thanks to software, now stitching together a poster is only about getting the image right. I also managed to create a few self made ones, but they were more of collages, a glued up motley of my favorite images. (And remember, just because a specification of your project says your code does not have to run on Linux, it does not mean it does never have to run on Linux.Growing up, I had to buy my posters and the larger the size, the higher went the costs. To be portable, better use runtime_error. The runtime_error class has a constructor taking arguments ( char*) on both platforms, Windows and Linux. Microsoft C++ has a constructor taking arguments in the exception class, but this is not standard. There are, of course, alternative ways to structure that hierarchy, which might be more appropriate in your design.Īs Loki Astari and unixman83 noted in their answer and comments below, the constructor of the exception class does not take any arguments according to C++ standard. As you see, they decided to split all exception types into "runtime errors" and "logic errors" and let you proceed from there with your own exception types. What you see in standard C++ library is one possible approach, offered to you by the authors of the language. Designing a useful exception class hierarchy (that would let you catch only the exception types you are interested in at each point of your code) is a non-trivial task. For example, catch (std::runtime_error& e) will catch all exceptions from std::runtime_error subtree, letting all others to pass through (and fly further up the call stack). Since 'catch' clause can catch polymorphic exceptions, the user can write 'catch' clauses that can catch exception types from a specific subtree of the exception hierarchy. The point of having this hierarchy is to give user the opportunity to use the full power of C++ exception handling mechanism. Just like std::runtime_error, standard library contains std::logic_error, also descending from std::exception. You can define your own exception classes descending from std::runtime_error, as well as you can define your own exception classes descending from std::exception. It can be thrown by itself, or it can serve as a base class to various even more specialized types of runtime error exceptions, such as std::range_error, std::overflow_error etc. Std::runtime_error is a more specialized class, descending from std::exception, intended to be thrown in case of various runtime errors. In other words, conceptually it is an abstract class (even though it is not defined as abstract class in C++ meaning of the term). Print your document to a new 'virtual printer' and a preview dialog lets you enlarge to create a poster or print as normal. Allows you to create a poster from ANY document that you can print from ANY application. Std::exception is the class whose only purpose is to serve as the base class in the exception hierarchy. Designed for splitting large maps for easier printing on A4 papers.
