In this iText 5 example, we need to switch between different styles in the same document: The best way to do this in iText 5, is to create a convenience method that creates a Chunk in the style that needs to be used frequently; see the createBgChunk() method: public Chunk createBgChunk(String s,...

In this iText 7 example, we need to switch between different styles in the same document: The best way to achieve this in iText 7, is to create a Style object, and to apply that Style to a Text object: public void createPdf(String dest) throws IOException { PdfDocument pdf = new PdfDocument...

There are many ways to communicate with servers using Unity as the client (some methodologies are better than others depending on your purpose). First, one must determine the need of the server to be able to effectively send operations to and from the server. For this example, we will send a few pie...

In this example, we'll create the following table using iText 5: We need the PdfPTable and PdfPCell class to achieve this: public void createPdf(String dest) throws IOException, DocumentException { Document document = new Document(); PdfWriter.getInstance(document, new FileOutputStream...

In this example, we'll create the following table using iText 7: We'll need the Table and Cell class to achieve this: public void createPdf(String dest) throws IOException { PdfDocument pdf = new PdfDocument(new PdfWriter(dest)); try (Document document = new Document(pdf)) { T...

Suppose that we have the following text file: jekyll_hyde.txt How do we convert it to a PDF that looks like this: Note the blue border that is added to the titles, and the page number at the bottom of each page. In iText 5, these elements are added using page events: class MyPageEvents extends ...

Suppose that you have the following text file: jekyll_hyde.txt How do we convert it to a PDF that looks like this: Note the page numbers at the bottom of each page. These are added using an IEventHandler implementation: protected class Footer implements IEventHandler { @Override pub...

Suppose that you have the following text file: jekyll_hyde.txt How do we convert it to a PDF that looks like this: Note that this is very similar to what we had before, but the border of the titles now has rounded corners. We created a custom ParagraphRenderer to achieve this, and we created a T...

Suppose that we want to create a simple Hello World document: In iText 5, this would be done like this: public void createPdf(String dest) throws DocumentException, IOException { Document document = new Document(); PdfWriter.getInstance( document, new FileOutputStream(des...

Suppose that we wanted to create a simple Hello World document: In iText 7, we could do that like this: public void createPdf(String dest) throws IOException { PdfDocument pdf = new PdfDocument(new PdfWriter(dest)); Document document = new Document(pdf); document.add(new Paragraph...

A session is simply an array consisting of the following user information: The user's unique Session ID (this is a statistically random string with very strong entropy, hashed with MD5 for portability, and regenerated (by default) every five minutes) The user's IP Address The user's User Agent ...

In the .bashrc or .bash_profile, adding: export MYSQL_PS1="\u@\h [\d]>" make the MySQL client PROMPT show current user@host [database].

Objective-C NSPredicate *predicate = [NSPredicate predicateWithBlock:^BOOL(id item, NSDictionary *bindings) { return [item isKindOfClass:[UILabel class]]; }]; Swift let predicate = NSPredicate { (item, bindings) -> Bool...

Objective-C NSPredicate *predicate = [NSPredicate predicateWithFormat: @"self[SIZE] = %d", 5)]; Swift let predicate = NSPredicate(format: "self[SIZE] >= %d", 5) In this example, the predicate will match items that are arrays with length of at least 5.

An NSPredicate can use substitution variables to allow values to be bound on the fly. Objective-C NSPredicate *template = [NSPredicate predicateWithFormat: @"self BEGINSWITH $letter"]; NSDictionary *variables = @{ @"letter": @"r" }; NSPredicate *beginsWithR = [templ...
