To use this ASP component move the DLL into a subdirectory
(like \winnt\system32 for NT or \windows\system for Win95). Please use the version of
regsvr32 that is included with this component or the version that comes with Microsoft ASP
(they are the same version).
To register the component on the system change to the directory
where you installed the DLL and type:
Simple Image Example
Using the component is as simple as
- Creating the object
- Setting a few properties
- Calling the SaveImage method
The following code demonstrates how to use ASPImage from VBScript.
In this example we'll create a text image that say's "Welcome to" with a
Set Image = Server.CreateObject("AspImage.Image")
rem Set various font parameters
Image.FontColor = vbBlack
Image.Italic = True
Image.Bold = True
Image.FontName = "Arial"
Image.FontSize = 12
Image.PadSize = 10
rem Calculate how big our text info is and set the image to this size
rem This has to be done since we want to fill the area with a gradient
strMessage = "Welcome to"
Image.MaxX = Image.TextWidth (strMessage)
Image.MaxY = Image.TextHeight (strMessage)
rem Create a one way gradient
Image.GradientOneWay vbRed, vbWhite, 0
rem Print our string to the image
Image.TextOut strMessage, Image.X, Image.Y, false
rem Set the filename and save
Image.FileName = "d:\inetpub\wwwroot\images\msg1.jpg"
if Image.SaveImage then
rem The image was saved so write the <img src> tag out for the browser to pick up
Response.Write "<img src=""/images/msg1.jpg""><br>"
rem Something happened and we couldn't save the image so just use an HTML header
rem We need to debug the script and find out what went wrong. See Image.Error for details
Response.Write "<h2>Welcome to</h2>"
By testing the result of the SaveImage method we can determine if
the image save was successful or not. If something happened that causes the image not to
be saved it probably means the script is saving the image to an invalid directory or a
directory where write rights do not exist.
Images can be loaded or manipulated and then as these modifications
occur you can save them to an animated sequence using the call AddImageToAnimation. A
simple example of GIF animation can be found in soianim.asp which is included with the
eval zip file for AspImage.

Failures reading and/or writing image files.
Check directory security and make sure that the IIS user (authenticated and/or anonymous)
has security permissions that allow read/write to the directories in question. The same
problem may occur when using the AddImage method. If this fails make sure the image file
is valid and that proper security permissions have been granted for the component to
access the file.
