before asking the list, I have tried quite some time - but I'm at my
I want to create a LARGE background image which is a sort of gutter. I
think I can do this by creating a picture, but I don't find out how to
draw lines of patterns in a picture under script control.
If I have this background image, it's very easy to group it so I can
use scrollbars to scroll it. Once I have it...
Next I want to draw object son top of it. Ok, that's easy, once I know
how to draw...
Then I want to replace parts of the picture, because the user must be
able to move a virtual object by dragging it somewhere else. In RB this
is quite simple - but how can I tell Rev to redraw patterns only in a
specified rectangle (a sort of CliptRect)?
Back in the good old days of Pascal, I declared the CliptRect, painted
the whole picture, and I was sure that only the ClitpRect was painted -
performance was excellent event on a 68000. There was something as easy
as lineTo - but what is the equivalent in Rev? It must be there,
because I can use the paint tool to draw lines, patterns and so forth -
but how to do it under script control?
Thank you for giving me some hints!
