Re: [mapguide-users] trouble replicating interstate symbol definition

Thu, 07 Aug 2008 08:40:15 -0700

I have been using Studio to create my symbol definitions, and in its current form, your symbol gave an error. However, removing the <SimpleSymbol> and <RenderingPass> tags allowed me to save the symbol definition. Yet, I got the same result with this--nothing showed up on screen when I created the line. So, I tried substituting this into a <CompoundSymbolDefinition> along with some lines drawn representing a road, and only the road lines showed up on screen.
I have tried encoding my image as well, using a site I found that converts a file to base64, and that hasn't worked for me either. One question though: when I encoded my image, the base64 string was a lot longer, probably 10x or more as long. Does that seem normal? The image itself is under 6k. 

Thanks for your help.

I encode the image directly in the XML.  Try substituting your symbol

Has anyone else tried to implement interstate signs?
 
Thanks.

    only get the text to show up. Here's what I did:


     


    -downloaded image of highway badges

    -cropped image to one I needed

    -uploaded to symbol library through studio 2008

    -copy/pasted code for symbol definition and changed path

    -tried creating layer using pointing to symbol


     


    I first tried only the highway badge. But after that, I tried a

    CompoundSymbolDefinition that included 2 paths to draw the road in


        


yellow

  


    and black. Everything but the badge showed up. I thought maybe editing


        


the

  


    image caused some issues, but I was able to use the image as a W2D


        


stream in

  


    a PointSymbolization2D layer.


     


    Can anyone help me determine what I have done wrong here? My setup is


        


MGOS

  


    1.2, win XP, apache + php.


     


    I am including the files that I used to go through this process.
