I am concerned that the Qt subset of html is not expressive enough to produce decent layouts beyond simple tables. To get an idea what people’s paper divelogs look like in the wild, do a google image search for “dive log template”. Compared to what we have now, we need much better control over spacing (inclunding whitespace, there we currently waste far too much precious room on the paper), fields for which we don’t have information should in many cases not be displayed and the room be used for what we actually have etc. For me, for example, beyond the very basic information (date, depth, time, location, buddy), the notes are by far the most important textual element and should occupy sufficient room (in a decent font size).

TMK there are a couple of engines. there is one which is used by
QTextDocument, which is a HTML subset and lacks at certain areas like
CSS, and the other one is the WebKit engine which is like the backend
of a full-blown modern browser.

like i said in the previous email, i'm pretty sure we are going to
need WebKit, because QTextDocument is going to soon become sub-par for
our needs, which opens two questions:
- how fast is the WebKit rendering to QPicture / QPixmap?
- do we care that the Windows package is going to inflate 30+MB for
the release build (also it's probably going to require ICU which is
another 20+MB unless there is a way to use WebKit without ICU)?
