VB Graphics

Richard Newcombe takes a look at Bitmap Animations in VB.NET. VB6 made extensive use of API's to load and initialize large quantities of smaller images. .NET has the GDI+ dynamic library, with a large selection of graphic classes and functions, which means that we no longer require API's to manipulate images.

Discover how to Interact with the objects on a playing field. The article uses a game as a base for the code.

Discover how to render an image directly from a database using an IHttpHandler and how to modify the image on its way to the client using GDI+.

Round those corners and make your user interfaces a little jazzier with a rounded rectangle Panel control; a fun chunk of code to incorporate into your application.

Discover how to update the VB6 Asteroids project to run in VB.NET.

This time, you look at animating bitmap images and write a simple platform game. You also find out how to load images directly into memory without setting up a picturebox in design time.

Look at doing a simple stick figure animations, and then use similar methods to create a simple, fast-paced 2D vector animated game.

Discover a utility for quickly obtaining and managing rectangles within rectangles. The rectangles then can be used to do things such as manage the layout of dynamically generated forms or visualize LINQ queries.

There's no need to store file system paths in a database. Just store images in your database and then directly load them to your ASP.NET pages.

With this article, you will learn how to Crop, Zoom, and Rotate images. You also will learn how to make an Eyedropper, how to draw text, and how to make a moveable Selection.

You've learned how to render graphics with GDI+ and ASP.NET. Take the next step and learn how to dynamically update images with AJAX.

With Part 3, we add shapes like hearts, rounded rectangles, spirals, stars. We also experiment with different brushes to fill our shapes more nicely.

Web forms do not have a canvas, so you can't ask a Web form for its Graphics object. But, you can simulate this behavior by rendering graphics in ASP.NET—with some help from GDI+.

Given an image and a quadralateral, Aaform will fit the image onto the quadraleteral passed using geometry.

Rotate images using geometry.

Learn how to use Zip and Unzip compatible methods with VB5 or VB6. All the code is contained in class modules that can either be compiled into an ActiveX or dropped into an existing project. The Zip/Unzip functionality is handled by the FreeWare InfoZip components from (http://www.cdrom.com/pub/infozip ) - these DLL's are included in the download.
