Salut
This seems to work fine for me
blur = nuke.createNode(Blur)
checker = nuke.createNode(CheckerBoard2)
format_name = blur.format().name()
checker['format'].setValue(format_name)

Salut Hugo,
Thanks for the tip. Yes, this works for me too. However this will fail if
the current format of 'blur' is not named (for example by inheriting a
format created by a Read node loading some random image).

Hey everyone,
I'm bumping up this old thread because I'm not sure what's the current
'best practice' to link the format of a
checkerboard/constant/colorwheel/colorbars to the format of some other
random node that doesn't have a format knob (like, say, a Blur node).
This works:

I need to create a checkerboard inside a gizmo or group that inherits the
format of Input1. Anyone know how to do this easily? I know I'm missing
something simple here...
Thanks,

This is how I like to do it within my tools...
set cut_paste_input [stack 0]
version 6.1 v2
CheckerBoard2 {
inputs 0
name CheckerBoard1
selected true
xpos -625
ypos -613
}
Crop {
box {0 0 {Gather_Input_Data.myWidth i} {Gather_Input_Data.myHeight i}}
reformat true
crop false
name
thanks for this - I'm doing something similar right now (just with reformat
nodes... and it works), but I'm trying to get the checkerboard to get drawn
initially at the proper res without having to filter it. Any ideas?

OK, anyone: is there a way to call up in an expression the current format of
a node? Not the height and width, but the whole format?

I've tried to link pulldown knobs before in nodes like CheckerBoard using
setExpression() without success.The only way I have ever figured out how to
make this work is through a knobChanged callback. The approach is similar
whether it's a group or gizmo. Here are some examples to try in your
Hi Ron,
just trying to match the width and height of the node with the width and
height of one of the formats:
def getFormat(node):
w,h = int(node.width()), int(node.height())
for format in nuke.formats():
if w == format.width() and h == format.height():
print
this works on a label:
[python {[format.name() for format in nuke.formats() if
nuke.thisNode().width() == format.width() and nuke.thisNode().height() ==
format.height()]}]
don't know how to write that in tcl

I can't get it to work in a format expression panel myself.

AFAIK, you can't expression link certain types of pulldown knobs in Nuke.
Some work, some don't.
This doesn't work:
checkerboard_linked['format'].setExpression('checkerboard_master.format')
But this does:
nuke.toNode('Blur_linked')['filter'].setExpression('Blur_master.filter')
-E
set
FYI, there is now a node.format() method that returns the a format object.
Can't remember when it was introduced, but it's fairly recent (6.1v5?)
So you can do something like:
[python nuke.thisNode().format().name()]
...if you just want the name. Or...
[python nuke.thisNode().format().width()]
Hmmm...
Shame.
The main problem here is that the format property's expression panel isn't
like other expression panels. It doesn't accept any scripting, TCL or
Python. Only expressions.
Guess it's really down to one of those Python solutions.

Format knobs are the only ones you can't expression link (up until 6.2).
Other enumerations, including channel knobs , filter knobs, etc. were fine.
Pre 6.2, a knobChanged callback was the best (only?) way to make a format
knob drive changes to another format knob.
In 6.2, though, you can set an

Correct, Ivan.
But if you look at other types of properties, you can type python and tcl
commands in the expression panel instead of writing an expression. The
format enumeration doesn't allow for that, which makes the solution for
Julian's problem a much more difficult one.

Ah, cool. I'm on 6.1 so that makes sense. Nice to see this is fixed in 6.2.

I'm on 6.2... and next to every format pulldown in checkerboards and pulls
downs there's a little '=' button that allows me to 'set-link' I figured this
has got to solve my problem, but entering what I would expect to be the normal
solution... i.e.
'Input1.format'
returns nothing...

Julian, that's what I was trying to figure out for you, by using the
expression panel (that's what comes up by choosing the set link).
Seems like it's no use in this case though.

So from what you guys have said, if you're on 6.2, this is the expression to
use, Julian:
parent.input0.format
But Ron says that setting the format knob through the interface isn't
working, so I would try through python:
g = nuke.toNode('mygroup')
g.begin()
c = nuke.toNode('myCheckerboard')
thanks for the help guys got it working with that... It's so close to what
I was doing before :)
cheers,

Ivan,
of course you're right. The test I was doing had a format knob in the
input, so it worked. But actually we want a format object rather than a
knob.
