| Troubleshooting Python plugin to load an XCF file |
|

In connection with troubleshooting my bigger project (thread here: https://www.gimp-forum.net/Thread-Gimp-P...d-question) I'm trying to create a really simple plugin to open an XCF file in the GUI. Eventually I will make this non-interactive and make it a wrapper to launch my other function, but for now I just want it to open the GUI and use pdb.gimp_xcf_load to open my XCF.
I know definitions are not completely needed, but having them seems to make it easier to call a function from the command line, so I have a definition for now.
The command line opens the Gimp UI, but doesn't open my XCF, and throws some errors. Any idea what I'm doing wrong here in this very simple plugin?
Command line argument:
Code:
gimp --batch-interpreter python-fu-eval -b '(python_fu_open_xcf "/Users/TimB/Desktop/template.xcf")'
Plugin:
Code:
#!/usr/bin/env python
#
# Script to open .XCF file
from gimpfu import *
def open_xcf(file):
try:
# Open XCF file
image = pdb.gimp_xcf_load(file, file)
layer = pdb.gimp_image_get_active_layer(image)
except Exception as err:
gimp.message("Unexpected error: " + str(err))
register(
"python_fu_open_xcf",
"Add image to layer",
"Add image to layer and flatten.",
"TCB",
"TCB",
"2021",
"<Image>/Filters/Tim/Open XCF",
"*",
[
(PF_FILE, "file", "XCF file to open", ""),
],
[],
open_xcf)
main()
Terminal output:
Code:

| Gimp Python script file load question |

I have a working Gimp plugin that takes an open XCF, adds a new layer to it, positions the new layer, and then exports a JPG.
However, the plugin only works if I'm in the Gimp UI and the XCF file is already open. I want to run it from the command line and some how call pdb.gimp_xcf_load somewhere top open the XCF, but I can't get the file open or command line to work.
What is the best way to do this? Should I have a wrapper script that opens the XCF and then calls my working script? Or can I both open the XCF and the JPEG in a single plugin? Is there a best practice?

| Removing alpha channel |

I've recently had some issues with GIMP generating alpha channels after editing images when using layers. Upon exporting to .png, the alphas get left in. I'm being told by an ace programmer that this is a ridiculous thing that GIMP should not do. I really, really like GIMP, and would rather continue using it. Is there an update that deals with this without a plugin? And btw, I haven't seen a good plugin that even does decent batch alpha removal.

| Wrapping Text Question |

For some reason there is no POST THREAD button in GIMP 2.10 section. Therefore I posted here.
I can wrap text around a circle using TEXT ALONG PATH tool. I even know how to make my text taller by turning the text into a path and scaling the path. What I wanna do is take my text, make it taller, then wrap around the circle. After editing the text to make it taller, I cannot seem to figure out how to make the new later wrap around the circle as it is no longer actual text and there is no text to path option.
So how can I make the text taller then wrap on a circle?
