Hi Rich,
I did a quick test with Flex - see my code below for Flex version,
just change the image source to try it out...
The problem is that I am using an Image component - this is where it
differs from Flash because I tried dynamically loading an image with
Loader in Flash and that was okay too.
Anyway, in Flex it appears I have to call UIComponent.validateNow()
to make sure any changes to the properties that affect drawing / layout
are done immediately - Grrrr, so much for simplicity and Flash = Flex as
far as AS3 code is concerned.
So, your code works fine, I guess mine was probably nearly okay and
that's another flippin' gotcha.
Thanks
Glen

Again, quick experiment.
If I do all my scaling of the image when it is loaded, rather than inside
the started printjob, it works, so I think the problem is with Flex / Flash
Player not updating my sprites / images on stage in time for them to be
printed.
No, I now think even more that it's the post-calculation rect. See my other
email and let me know if I'm right.
I did notice a bug, however, which may be in the Flash Player. Or, I'm too
rushed to notice how to fix it. Only when the orientation is changed to
landscape does the sprite scale and not restore. See my comments. I'm
looking for info and will log a bug.
Incidentally FlexPrintJob will do all the scaling for you, but this
results in it printing more pages than I want for a 2 page spread (6), so I
still have to scale my image, which makes the FlexPrintJob class redundant.
Good. I feel better. Heh.
