ASP Image Usage Example

Using the Aspimage component requires only the following steps: Build an Object Set several properties Calling the SaveImage method The following code gives an example of how to use the Aspimage component in VBScript, in which we create a text picture that is progressively populated with the words "Welcome to": 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 we text info is and set the "to" size Remthis has to being 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 Remnote:you should gen the filename dynamically for multiuser usage Image.filename = "D:inetpubwwwrootimagesmsg1.jpg" If Image.saveimage Then REM The image is saved so write the tag out for the browser to pick up Response.Write "<br>" Else Rem Something happened and we couldn ' t save the image so just use an HTML header Remwe need to debug the script and find out what went wrong Response.Write "End If By using the SaveImage method, we can tell if the picture has been saved correctly. Generally, the reason why the picture is not saved correctly is that the picture's save path is not valid or does not have permission to write to the path. GIF Animations Pictures can be loaded or processed, and you can save them to an animation in an active order by calling the AddImage method.
