We have a requirement to create a number of Graphs as PNG files and return them directly to user's browser as PNGs.

When you SAVE or HOLD the graph you get just the PNG file but when PCHOLDing the graph you get the PNG along with a HTML page that included the Image Map.

We could potentially consume the HTML page and extract the PNG file but what we really want to do is to just return the PNG file directly without the overhead of the MAP.

Anyone ever done this? I'm hoping it is just a SET command but haven't found the right one yet.

Cheers

Stu

Have you tried setting HTMLFORMTYPE to PNG and use -HTMLFORM {ddname} pointing to the PNG file.

May not work, but .....

Thanks Tony and Waz,

I had tried -HTMLFORM and that was going to the last resort as it still wraps extra HTML code around the image itself.

Fortunately EX EDAGET send the raw PNG without any extra baggage to be stripped of.

One note for the curious, if you are running this through WF8 content area then change EX to EXEC or add -MRNOEDIT before EX EDAGET.

Thanks

Stu

Yes, anything in the content area is scanned for -INCLUDE or EX, because it wants to find all fexes to ship to the WebFOCUS server for execution.
