First of all, in Python s regular-expression syntax, a set of parentheses whose contents begin with P, followed by a name in brackets and a pattern, matches a named group. That is, any text that matches one of these parts of the URL will go into a dictionary, where the keys are the bracketed names and the values are the parts of the text that matched. So this URL is looking for four named groups: year, month, day, and slug. The actual patterns used in these named groups are fairly simple once that hurdle is cleared: The \d{4} for year will match four consecutive digits. The \w{3} for month will match three consecutive letters: the %b formatter you used in the get_absolute_url() method will return the month as a three-letter string like oct or jun. The \d{2} for day will match two consecutive digits. The [-\w]+ for slug is somewhat tricky. It will match any sequence of consecutive characters where each character is either a letter, a number, or a hyphen. This is precisely the same set of characters Django allows in a SlugField. c# convert pdf to image itextsharp: iText - Convert PDF to Image pdf to image conversion in c# How to use Ghostscript for converting PDF to Image - Stack Overflow

We have already encountered a situation in which the Mapper class displays a natural fault line. The createObject() method is used internally by Mapper, of course, but Collection objects also need it to create domain objects on demand. This requires us to pass along a Mapper reference when creating a Collection object. While there s nothing wrong with allowing callbacks (as we do in the Visitor and Observer patterns, among others), it s neater to move responsibility for domain object creation into its own type. This can then be shared by Mapper and Collection classes alike. The Domain Object Factory is described in Data Access Patterns. Liferay version 5.1.1 comes with the Mail application, but version 5.1.2 (the current version at the time of this writing) does not. So you ll need to download this mail-client application from the Liferay web site. c# pdf to image convert How to convert " PDF TO IMAGE " in c# ? - C# Corner

When a URL matches this pattern, Django will pass the named groups to the specified view function as keyword arguments. This means the entry_detail view will receive keyword arguments called year, month, day, and slug, which will make the process of looking up the entry much simpler. Let s look at how that works by writing the entry_detail view: def entry_detail(request, year, month, day, slug): import datetime, time date_stamp = time.strptime(year+month+day, "%Y%b%d") pub_date = datetime.date(*date_stamp[:3]) return render_to_response('coltrane/entry_detail.html', { 'entry': Entry.objects.get(pub_date__year= pub_date.year, pub_date__month=pub_date.month, pub_date__day=pub_date.day, slug=slug) }) The only complex bit here is parsing the date. First you use the strptime function in Python s standard time module. This function takes a string representing a date or time, as well as a format string like the one passed to strftime(), and parses the result into a time tuple. All you need to do, then, is concatenate the year, month, and day together and supply the same format string used in the get_absolute_url() method. Then you can pass the first three items of that result into datetime.date to get a date object. Imagine a set of Mapper classes, broadly organized so that each faces its own domain object. The Domain Object Factory pattern simply requires that you extract the createObject() method from each Mapper and place it in its own class in a parallel hierarchy. Figure 13-7 shows these new classes: Figure 13-7. Domain Object Factory classes Domain Object Factory classes have a single core responsibility, and as such, they tend to be simple: abstract class woo_mapper_DomainObjectFactory { abstract function createObject( array $array ); } Here s a concrete implementation: class woo_mapper_VenueObjectFactory extends woo_mapper_DomainObjectFactory { function createObject( array $array ) { $obj = new woo_domain_Venue( $array['id'] ); $obj->setname( $array['name'] ); return $obj; } } Of course, you might also want to cache objects to prevent duplication and prevent unnecessary trips to the database as I did within the Mapper class. You could move the addToMap() and getFromMap() methods here, or you could build an observer relationship between the ObjectWatcher and your createObject() methods. I ll leave the details up to you. Just remember, it s up to you to prevent clones of your domain objects running amok in your system! To add the Mail application, follow these steps: 1. Log in as Administrator to your ISI portal. 2. Create a new page called Collaboration. You ll use this page to add and test all the applications I ll discuss in this chapter. c# split pdf into images how to convert pdf files to image - Stack Overflow
