Things should always work the way
users expect, but sometimes implementation gets in
the way.
The output side of the operator is
calculated by the algorithm, it is the true size that the effect will produce
given its input parameters. The Resize node is just a different UI on the
transform 3D, so when you put an exact pixel value what it does is in fact
figure out the right numbers to poke in a transform matrix to produce the
output. The image size produced is the result of that matrix transform,
not the number you entered you entered in the PPG. It must work this way
because I need to stamp out any time that the results are not correct, and not
hide the bugs by forcing the output to exact pixel. Which would give an
image the right size, but with some aliasing garbage or missing lines.
I'd like to have clear repro steps on
how to have it not work right, so we can address any remain
issue.
Note that you need to try this with a
scene created at least in XSI 4.2, because the resize node checks the scene
version and emulates old bugs in order to maintain compatibility. If you
worked around a bug, for example by adding 1 to the desired size, I must
maintain that behaviour in existing scenes. Cuz I'm that nice of a
guy.

Re: resize node in FX tree
There was that old one - where absolute pixel
sizes were 1 pixel wrong, but I haven't seen it recently.
In fact, I always wondered how you got rounding
errors on pixels. Aren't they always integers?

I have a code defect logged by
Kris Rivel against the Resize node, but we couldn't reproduce it. No
doubt this would be a simple math rounding error, so
it must be specific to some source image size.

Did you also checked Apply Crop in Output Crop [720
486]?

Transform3d doesn't work I don't think. How do you set it
to 720x486? I tried adjusting the y scale to a value of .8 which it
says is 720x486 but clearly its now too
squashed.

So what is the result at the end when you go through Resize or Transform3D?
Do you get visual problems, fragments or is the color depth of the original
input messed up?
When I try here I don't see any problems I know from Tint here ...

No floating support unfortunately.

Talking about that... it doesnt handle floating point images right?
i loaded an hdr image resized it and boom i had an ldr.
am i right or im missing something.
sorry to hijack the thread. v 4.2 btw

Any chance the resize node in the FX Tree could be fixed!!! That
thing is
driving us nuts for the past few versions of XSI.
