Neodynamic ImageDraw for ASP.NET is a .NET server control which generates real time on-fly images for ASP.NET Web Applications. ImageDraw allows you to use all the potential of GDI+ in your ASP.NET Web Applications. You can use ImageDraw to deliver real time dynamically generated images such as charts, diagrams or any other graphical application.
The Image WebControl built-in .NET Framewrok is useful to render static image files, but suppose you need to convert the original image into another image format, resize it in a given size, add your own captions on it, convert it to grayscale version, and so on. In those cases you can use Neodynamic ImageDraw WebControl.
　
Renders Static Images
If you have an image file (gif, jpg/jpeg, exif, tiff, ico, bmp, or png) specify it into ImageDraw's ImageUrl property. Specify the Image Format (gif, jpg/jpeg, bmp, or png) to render and you are done.

Renders Dynamic Images
With ImageDraw you can render an image object using all the potential of GDI+. For example you could render a statitics chart. Specify the Image Format (gif, jpg/jpeg, bmp, or png) to render and you are done.

Image Formats supported
ImageDraw can render all raster images (also called bitmaps) supported by .NET Framework through the GDI+ Bitmap Object. These image formats include: BMP, GIF, JPEG/JPG, EXIF, PNG, TIFF, and ICO.

• ImageDraw for ASP.NET supports some built-in effects such as:
  • Stretch (Size Effect): When you resize the image on your WebForm at design-time, the image is stretched to the new dimensions.
  • Scale (Size Effect): When you resize the image on your WebForm at design-time, the image is scaled to the new dimensions.
  • Grayscale (Image Effect): Convert the image to gray scale.
  • Negative (Image Effect): Convert the image to negative.


• In the following table you can see which image formats ImageDraw accepts as input and which image formats it can render.

Visual Studio design-time support
ImageDraw for ASP.NET presents a powerful designer and utilities. When you drag & drop ImageDraw from Visual Studio Toolbox, the ImageDraw Designer shows you the output image that ImageDraw will render at runtime.

• ImageDraw for ASP.NET works in most popular and modern .NET Development Tools including:
  • Microsoft Visual Studio .NET 2002
  • Microsoft Visual Studio .NET 2003
  • Microsoft Visual Studio 2005
  • Microsoft Visual Web Developer 2005 Express Edition


• ImageDraw takes full advantage of the new design improvements within Visual Studio 2005 including a useful Smart Tag associated to it as is shown in the following figure.
