Hi, I'm new to SVG (and not very experienced with Javascript, either) and I've run into a problem trying to integrate my SVG drawing tools into my ASP.NET project.
I'm working on a mapping application. The maps are generated using a third party tool that creates jpg images. The third party tool is contacted and the image URLs are sent to my app using a .NET dll. My SVG drawing tools use the map as a canvas, so I need the image in the SVG file. When the users make changes to the map, a new jpg is generated and I need to update the reference and refresh the image. I can do this in JavaScript, but I can't reference the Javascript function from my app without using a button. I need this to be done transparently -- I can't require the users to click a button every time they make a change. Today I tried putting the SVG in an aspx file and generating the SVG on the fly. This worked great, and then it just stopped working -- I have no idea why. I have an web page file that contains an embed tag: <embed id="embedImage" height="400" width="400" pluginspace="http://www.adobe.com/svg/viewer/install/"; type="image/svg+xml" runat=server></embed> In the code behind of that page, I have this code: strURL = "DefaultMap.jpg" embedImage.Attributes("src") = "http://localhost/svgtest/ImageSVGNew.aspx?url="; & strURL (My plan was to create a little function that accepted the URL and passed it to the src attribute of the embed tag The SVG aspx file contains the following: <%@ Page Language="vb" %> <% dim strResponse as string strResponse = "<?xml version='1.0' encoding='UTF-8' standalone='no'?>" strResponse = strResponse & "<!DOCTYPE svg PUBLIC '-//W3C//DTD SVG 1.0//EN' 'http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd'>" strResponse = strResponse & "<svg xmlns='http://www.w3.org/2000/svg' xmlns:xlink='http://www.w3.org/1999/xlink' width='400' height='400'>" strResponse = strResponse & "<svg>" strResponse = strResponse & "<image id='imgMap' xlink:href='" & Request("url") & "' x='0' y='0' width='100%' height='100%' />" strResponse = strResponse & "</svg>" response.write(strResponse) %> I'm guessing that the problem has to do with the order that things are processed and rendered. I don't understand, though, why that order would change? Does anyone see what I'm doing wrong? Can anyone think of a better way to do this? Thanks, Chris ------------------------ Yahoo!
