Hi newwahm
I'll be happy to answer as best I can and hopefully others
will chime in to fill in what I'm unable/unqualified to answer. You
didn't say which RoboFlavor you are planning on using (RoboHelp for
Word or RoboHelp HTML) so please know that my answers are related
specifically to RoboHelp HTML.
1) The ability to create text on top of a graphic?
This is possible, but may not work as you would think. When I
think of placing text on a graphic, I think of opening the graphic
image in an image editing application such as Microsoft Paint or
Adobe Photoshop or Fireworks. Then placing the text where I want it
and saving the modified image where the text is actually part of
the image. But you actually *CAN* accomplish this by using
Positioned Text Boxes in RoboHelp HTML.
2) The ability to add comments to the output file?
Using a workaround and some "outside the box" thinking, sure!
But there is nothing in the RoboHelp application that would
directly facilitate this.
3) The ability to merge changes from different users to the
same output file?
Hmmm, this won't be possible if you are talking about the
RoboHelp output file(s). But if you are talking about the source
files used to create the output, you could accomplish it by either
using manual source control or a source control application.
RoboSource Control ships with RoboHelp and you could also acquire
Microsoft Visual Source Safe (VSS) separately.
4) The ability to go from one page displaying in Protrait,
the next in Landscape, and then back again to Portrait, all within
the same document?
I'll have to defer that one. It sounds like you are referring
to creating printed output. I tend to avoid creating printed output
if I can. I take the stance that it's called "On-Line Help" for a
reason. And, there's that silly notion about actually liking trees.
5) Templates or Style Sheets to work from?
RoboHelp HTML supplies a few pre-defined style sheets you may
use. You are also free to import or create your own! As for
templates, these are easy to create using RoboHelp. However, there
aren't any pre-defined templates I'm aware of.
6) The ability to do conditional text, or tagging, for
specific versions?
Ab-so-freakin-lute-ly! In the most recent version, conditions
may be applied to entire topics, text, images and objects inside
topics, TOC nodes or Index terms. And to go even further, version 6
also offers variables, which can reduce (and in some cases
eliiminate entirely) any need for conditions.
What is the learning curve for the software?
Personally, I think the learning curve is pretty easy.
RoboHelp handles all the heavy lifting for you and shields you from
having to know any coding that is needed behind the scenes.
If you are interested in training, I'm also an Adobe
Certified RoboHelp and Captivate instructor. I'd be happy to try
and hook you up with some formal training.
Hopefully this was helpful... Rick
