Several image file formats enable you to store metadata along with an image. Metadata is information about an image, for example, title, width, camera model, and artist. Microsoft Windows GDI+ provides a uniform way of storing and retrieving metadata from image files in the Tagged Image File Format (TIFF), JPEG, Portable Network Graphics (PNG), and Exchangeable Image File (EXIF) formats. In GDI+, a piece of metadata is called a property item, and an individual property item is identified by a nu...

We can use GDI+ to draw chart components in C# or VB.NET language in memory and once the components are drawn in memory, we can save the drawing in an image on the Web server. Once the image is saved, we can display this image in an ASP.NET page using any Image tag or image control....

jThermometer is a class for creating thermometer charts of the type used generally to show progress toward a fund raising goal. It arose out of my involvement in a charity walkathon. The organizer wanted to have a thermometer-type chart on a the walkathon's home page to indicate progress toward fund raising goals. I was unable to find anything free that seemed appropriate for the site so I decided to create my own and share it here on Code Project.

The chart uses GDI+ to compose an image ...

Have you ever had the need to generate images on the fly in your ASP.NET applications? You could use GDI.NET to do this directly, but we think we have an easier way. Enter ImageTemplate.NET. ImageTemplate.NET lets you configure an image template in an XML file and then change the image that is generated by passing parameters in the URL.

This is great for dynamically generating images based on database content. ImageTemplate.NET can help you: -

* Rotate Images

Create Snazzy Web Charts and Graphics On the Fly with the .NET Framework

Knowledge workers can understand data more effectively when raw numbers are presented in a graphical format. This is especially true when displaying database information on a Web page, where a simple chart can make the difference between a dry presentation and a vivid data source. In the past, creating dynamic, data-based charts on the fly in ASP required purchasing a third-party, image-generating COM component. Now with ASP.NET, developers can access the .NET Framework's drawing classes directl...

Building Dazzling Charts With Office Web Components

Any time you need to add killer 3D charts to your web application you probably jump online and start looking for component vendors. Or you open up an issue of the MSDN Magazine (which looks more like a JC Penney catalog these days, no less) and do the same. I think charting components are way overpriced and overrated. I'd like to know how many people actually use triple nested datagrids? No, really? I'm not talking about MSDN articles which do it for show-and-tell. I mean real-life solutions. Be...

The .NET framework has made working with bitmaps very easy, but it can be a puzzle if you are still thinking in terms of GDI or VB6 graphics. The basic operations that we all need to master are how to load an image, how to scale and crop it, and finally how to rotate it.
Start a new VB Windows form project and place a button and two PictureBoxes on the form. All of the code described in the rest of this article can be placed in the button’s click event handler for testing....

Voice recognition technology has arrived; it's stable, it's standardized, it works, and there's demand for it. In this article, we will take you step-by-step through the process of building a demo application called "Commerce Voice."

When you think of the phrase "charting on the Web", you probably think of COM components, .NET assemblies, or extensions (like Office Web Extensions). While these are great ways to chart your data, they do put a strain on the system when you need to chart data for thousands of concurrent users. They also come with installation hassles and high-priced licensing policies. You might also think of plain "nested-table" HTML charts, but these don't really make a very big impact on the end-user....

Creating Graphics On-the-Fly in ASP.NET

Creating graphic for use in your web page is a snap in .NET. In this example I will be using VB.NET to create a graphic file for use in a page. Since this graphic will be hosted in an Image server control you will have full access to placement, sizing and other properties.
This example will persist the graphic out as a temp file. I know, I know, my first thought was "And now we will have server space issues dues to 1000's of temp files!" In the next tutorial in this series I will present a si...

This article examines a custom ASP.NET server control I developed to make using the Google Maps API easier for .NET developers. This article assumes you are somewhat familiar with Google Maps (or are at least somewhat curious). If you're not familiar with Google Maps or its sweet API, for the lowdown. You may see references throughout the article to "my control, my GoogleMaps control, my GMap control, and so forth." I did not create the Google Maps API; I merely used C#, XML, and XSL to create a...

This article will show you how you can easily make your custom controls skinned by deriving from a new control class that we will call SkinControl. SkinControl is an abstract class and derives from Control class, and introduces a new property and a few methods. These methods and the property is what will actually build the skin – one of the methods, Initialize, needs to be overridden by each control you want to be skinned. This must be done because it is in this method where you initialize all t...

By default the JPEG files that GDI+ outputs can sometimes look a little crummy. This is because they are not output at the highest possible quality. While this can be frustrating if outputting something that requires clean lines, such as text, you rarely notice much with photographs. But what about if you need your picture to look crisp but can not use an alternative format such as GIF or PNG?...

One of the things I love about ASP.NET is the fact that the entire Microsoft .NET framework is at your fingertips. Third-party components or extremely convoluted ASP code (for seemingly simple tasks, such as uploading a file) no longer constrain you. Now you can handle almost any issue thrown your way with amazing grace and power....
