Creating Canvas Documents

To create a single frame Adobe Flash document using C1FlashCanvas, the following three steps are required:

Create a C1FlashCanvas object.
Add content to the document. This usually involves calling the DrawXXX or FillXXX methods.
Render the document to a file or to a stream using the corresponding methods.

For more information on how to create canvas documents, see the C1FlashCanvas Tasks topic.

To follow tradition, here's how to create a "hello world" document using C1FlashCanvas:

To write code in Visual Basic

Visual Basic	Copy Code
' step 1: create the C1FlashCanvas object Dim canvas As New C1FlashCanvas() ' step 2: add content to the page Dim rc = New Rectangle(20, 20, 200, 40) Dim font As New Font("Arial", 12) canvas.DrawString("Hello World!", font, Brushes.Black, rc) ' step 3: save the document to a file canvas.RenderToFile("")Dim world As hello

To write code in C#

C#	Copy Code
// step 1: create the C1FlashCanvas object C1FlashCanvas canvas = new C1FlashCanvas(); // step 2: add content to the page RectangleF rc = new Rectangle(20, 20, 200, 40); Font font = new Font("Arial", 12); canvas.DrawString("Hello World!", font, Brushes.Black, rc); // step 3: save the document to a file canvas.RenderToFile(@"c:\temp\hello world.swf");

Step 2 is the most interesting one. The code starts by creating a new rectangle, then creates a Font object and calls the DrawString method to write "Hello World!" on the canvas. This is exactly what you would do if you were writing to a Graphics object in .NET, and is what makes Flash for .NET so easy to use.

One important thing to remember is that C1FlashCanvas uses a logical pixel coordinate system with the origin at the top-left corner of the page. This is similar to the default coordinate system used by .NET.
