It’s a sample point. Use the move tool and drag it off the image canvas.

[Gimp-user] gimp-drawable-invert parameters

[HeyJC]

Hello,

I am attempting to update the Saul Goode version of the Create Luminosity Masks
Script-Fu script, sg-luminosity-masks. It works fine in GIMP 2.8, but I have
just updated to GIMP 2.9.8 to take advantage of the automatic link to darktable
for importing RAW images.

When I first ran the script it ended with an error based on the use of
deprecated functions in the script. I replaced the function names with the newer
versions and the script starts to work but I eventually get the following error
message:

Execution error for 'Luminosity Masks (saulgoode)':
Error: Invalid number of arguments for gimp-drawable-invert (expected 2 but
received 1)

I have looked for a function reference for the gimp functions called in
Script-Fu without finding anything. I've also searched for the proper parameters
for gimp-drawable-invert but am also coming up blank.

Can anyone help with either a current function reference or the parameters for
gimp-drawable-invert. I've attached the original script for reference.

Thank you!

[Gimp-user] Arrays in Python

That's one of Python's strongest points, though. Just import everything you
don't want to deal with yourself.

They should already be able to call the code by running ".plugin.main()" from
the module. right?
*tests*
Nope. NVM. Don't have access to the image/drawable variables if called from
within another script. Will make main() a separate function instead of part of
the class. The GUI already doesn't call it directly, so it should be easy to
fix.

Ok. Enter Key works. Thanks.

though having to press the enter key.

I too, often receive  bursts of 'late' messages but today[April 10, 2018] is

dated March 15, 2018 with the subject line 'How to print'. Ironically, this is

I made their web site install by just typing "make", basically. So now I 
wonder if it is a clog in the approval filter which is perhaps on

Re: [Gimp-user] Arrays in Python

[Joao S. O. Bueno]

It is just Python -

Just use on the calee script an inner function - one to be publicly
exposed on the PDB taking user arguments, and
another one internal meant to be called from other Python functions .

On this, simply use a Python list.

You can manipulate `sys.path` in order to be able to import other
installed GIMP scripts PY files.

Just don't expect the Procedural Database way of calling parameters,
essentially created more than
20 years ago with Scheme/lisp in mind to be able to handle the
flexibility one have in modern Python
parameter passing.

If you need the user to feed in several numbers on the UI, and wants
to use GIMP-FU,  (and not
design your own custom GTK UI), my suggestion is to use a string, and
tell the user to separate the nubmers by spaces
or commas  - on the Python side, you just split and convert the argument.

Other than that, yes, GIMp-Fu should be able to handle these PDB
arrays as arguments - despite
the workarounds I just described.
Could you can fill a bug in bugzilla about that?

Regards,

   js

I use a Wacom Intuous Small (CTL480). I think it was around 60 EUR when 
I got it a few years ago. It works perfectly with GIMP (on Debian

My only complaint is that it doesn't work after I wake up the computer

The user already can. I wrote a custom system for making GTK configuration

that just stacks all the widgets into a grand tower of Babel.
Where the enums come into play is allowing other scripts to call this one via
the PDB. Not really a problem right now since the registry's dead and therefore
it won't end up in the hands of others for a while (right?). I'm just

Guess for now I'll refactor it to make the PDB method take i32's & floats

they'll just have to import the class.


If anyone else knows a way or has other inquiries, I'll stay subbed to this
thread.





Or maybe your array can be pixels values in a layer (these are easy to
get in Python) in which case the user would just specify a second
layer.

You say that, but I was entirely unable to get proper pixel info in one of my
past scripts. I could get standard 8-bit info, but no 32-bit floating point info
that everything apparently uses now (2.10 RC-1).
Unless I'm completely missing it, the python-fu docs are patchy at best. Most of
my knowledge comes from trying to interpret the auto-generated pydoc stuff,
incomplete docs from like 4 years ago, or reverse engineering other over-the-top
scripts like LayerFX.

I have rarely seen  a Python script use another, most people would just 
copy the code they need to avoid the dependency. And you can factor you 
code to have a class that does the work and a registration facade, so 
that other Pythin script can import you code and call the useful code 
directly.
