We provide conversion to all image formats supported by .NET framework via System.Drawing. Image class so you are able to export PDF files to BMP,JPG, PNG ... Now you need to deal with the problem of the get_absolute_url() methods. On the Entry model, get_absolute_url() returns a URL with /weblog/ hard-coded into it, and that s no good. Somebody might plug these URLs into a different part of their site s URL layout. The solution is a pair of features in Django: one lets you give names to your URL patterns, and the other lets you specify that a function like get_absolute_url() should actually return a value by looking for URL patterns with particular names. First, you need to make one more change to the weblog URLConf: urlpatterns = patterns('django.views.generic.date_based', (r'^$', 'archive_index', entry_info_dict, 'coltrane_entry_archive_index'), (r'^( P<year>\d{4}/$', 'archive_year', entry_info_dict, 'coltrane_entry_archive_year'), (r'^( P<year>\d{4}/( P<month>\w{3})/$', 'archive_month', entry_info_dict, 'coltrane_entry_archive_month'), (r'^( P<year>\d{4}/( P<month>\w{3})/( P<day>\d{2}/)$', 'archive_day', entry_info_dict, 'coltrane_entry_archive_day'), (r'^( P<year>\d{4}/( P<month>\w{3})/( P<day>\d{2})/( P<slug>[-\w]+)/$', 'object_detail', entry_info_dict, 'coltrane_entry_detail'), ) You ve added a name to each one of these URL patterns. The names are made up of your application s name (to avoid name collisions with URL patterns in other applications) and a description of what the view is for. Now you can rewrite the get_absolute_url() method on the Entry model: def get_absolute_url(self): return ('coltrane_entry_detail', (), { 'year': self.pub_date.strftime("%Y"), 'month': self.pub_date. strftime("%b").lower(), 'day': self.pub_date.strftime("%d"), 'slug': self.slug }) get_absolute_url = models.permalink(get_absolute_url) The get_absolute_url() method now returns a tuple, whose elements are as follows: The name of the URL pattern you want to use A tuple of any positional arguments to be included in the URL (in this case, there aren t any) A dictionary of any keyword arguments to be included in the URL ghostscript pdf to image c#: extract JPEG from PDF by iTextSharp · GitHub pdf to image conversion in c# .NET Convert PDF to Image in Windows and Web Applications ...

Caution At the time of writing, Liferay version 5.1.2 had a few bugs in the Chat application, which were $obj->markClean(); } } As you can see, this is not an abstract class. Instead of itself breaking down into specializations, it uses the PersistenceFactory to ensure that it gets the correct components for the current domain object. Figure 13-11 shows the high-level participants we have built up as we factored out Mapper. The last line is a new concept: a decorator. Decorators are special functions that do nothing on their own but can be used to change the behavior of other functions. The permalink decorator you re using here (which lives in django.db.models) will actually rewrite the get_ absolute_url() function to do a reverse URL lookup. It will scan the project s URLConf to look for the URL pattern with the specified name, then use that pattern s regular expression to create the correct URL string and fill in the proper values for any arguments that need to be embedded in the URL. 1.

Some of the persistence classes developed in this chapter Aside from making the database connection and performing queries, the class manages SelectionFactory and UpdateFactory objects. In the case of selections, it also works either with a Collection class or directly with a DomainObjectFactory to generate return values. From a client s point of view, acquiring a DomainObjectFactory is easy. It s simply a matter of getting the correct concrete PersistenceFactory object: $factory = woo_mapper_PersistenceFactory::getFactory( 'woo_domain_Venue' ); $finder = new woo_mapper_DomainObjectAssembler( $factory ); Although, of course, it would be even easier to add a getFinder() method to the PersistenceFactory itself and transform the previous example into a one-liner like this: $finder = woo_mapper_PersistenceFactory::getFinder( 'woo_domain_Venue' ); I ll leave that to you, however. A client coder might then go on to acquire a collection of Venue objects: $idobj = $factory->getIdentityObject()->field('name') ->eq('The Eyeball Inn'); $collection = $finder->find( $idobj ); foreach ( $collection as $venue ) { print_r( $venue ); } If you do not have multiple machines for testing the Chat application, open another browser (not Tip another window of the same browser type) on your local machine. For example, if you re using Netscape, use Internet Explorer or Google Chrome for the second login. Now log on to the Liferay portal with some other account using this second browser. After you get connected to the portal, you will see that the number of Chat users has changed from zero to one. c# pdf image preview Windows 8 How to Convert PDF to Jpeg Image in C# sample in C# ...
