Instructions

Use the dropdown boxes below to change Web Graphical Text properties. Click the Update button to apply the changes to both Web Graphical Text s (streamed and filed).

Note that these properties represent only a small subset of the available properties.

 

How does the  Web Graphical Text work?

When a Web Graphical Text is set to function as a file, the image is created and saved as a file. Then the Web Graphical Text 's ImageUrl property (inherited from the Image web control class) is set to this file.

'The following is from the Web Shape code:
baseBitmap.Save(imgFile, Me.ImageFileFormat)
Me.ImageUrl = imgFile

When a Web Graphical Text  is set to work as a stream, the image is first saved as a MemoryStream and then written to the screen:

'The following is from the Web Shape code:
Dim memory As New MemoryStream()
baseBitmap.Save(memory, Me.ImageFileFormat)
memory.WriteTo(Page.Response.OutputStream)

What's going on with the 'streamed' Web Graphical Text  in this demo?

The streamed Web Graphical Text  is on its own form (streaming.aspx). That form is shown in an Image object (Image1) on this form (WebGTextDemoPage1.aspx).
