Yes, but perhaps not in the way you would expect.
If you are creating an HTML output (HTML Help, WebHelp) you can set a
background image to the topic body. Find the image you want and assign
it to the BODY. You then have a watermark on every page that uses that
Hopefully Willam won't mind my offering a teensy bit of clarification here. Note what he said about pages using that "style sheet".
To amplify that a bit, I'll spell it out because it's a wee bit on the tricksy side to locate exactly how to make the edit.
Look in your Project Manager pod to find your Style Sheet.
Double-click your style sheet to open it up in RoboHelp's Style Sheet editor.
Expand to the Other category, then click to select Background+Text(BODY)
Now in the lower left corner, click the Format button and choose Borders and Shading.
Then click the Shading tab
Thanks William and Rick. Your sugesstions were really helpful.
Your answer works like a charm for display in RoboHelp 9 program, but when I compile with WebHelp the "watermark" image does not display in the finished help screen. If I "Control-W" while in RoboHelp on that page the "watermark" displays, but it will not print with the topic. Am I doing something wrong on both of these issues?
With print to the topic, do you mean printing from a website? That is default behaviour as browsers disable that by default. There is no way to force this from a web site, though some browsers allow users to select adding background images.
Unfortunately, I don't have a good workaround for this either. If a watermark is important for content review etc. I would opt for a secured PDF. A web page simply isn't secure.
Thanks William. That's exactly what I meant - and I should have remembered that browsers, by default, don't print background images.
So, what am I doing wrong that the "watermark" won't display in my finished product when compiling with WebHelp? I see it fine in RoboHelp and if I press Control+W it displays fine - but after running the compiler I don't see it in the browser. Is there a step I'm missing?
Interesting. Are you certain the CSS specified in the project is the same one as assigned in the output? Does the CSS perhaps get rewritten on creating an output? If you open the developer console (F12) and select the body element, is the background image applied according to the developer options?
In past versions of RoboHelp, there was a little bug whereby if a watermark image was only referenced by the CSS, RoboHelp failed to note and include it.
Who knows, perhaps that bug returned?
To overcome it, we would add the desired image as a Baggage File.
