Hi
I have this plugin that just runs some other scripts and plugins.
I want to add the first 2 comments lines. Can somebody tell me if this is possible and fill in the required code?
The plugin works but the 2 first comment lines I don't know how to code it.
First I want to add an alpha layer to my image.
Then I want to apply "select by color" tool on a specified pixel (X and Y value of the pixel) and delete the selection from the whole image automatically? Is this possible using code?
Code:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import os
from gimpfu import*
def test(timg, tdrawable):
#how to add alpha layer to my image?
#how to apply "select by color" tool on a specified pixel and delete the selection from the whole image?
#determine the offset values manually
pdb.gimp_drawable_offset(tdrawable, 0, 1, 18, -32)
#the image size is constant and 150x150 crops the border
pdb.gimp_image_crop(timg, 2400, 1200, 150, 150)
#guides using script-fu
pdb.script_fu_grid_guides(timg, 0, 150, 150, 1, 0)
#chop into 150x150 tiles
pdb.python_fu_ofn_guillotine_layer(timg, tdrawable)
#export all layers
pdb.python_fu_ofn_export_layers(timg, os.path.dirname(timg.filename), "{numUp0}.png", "-", 0)
register(
"test",
"test",
"test",
"*",
"*",
"2024",
"<Image>/Tools/test...",
"*",
[],
[],
test
)
main()

Hi
What's wrong with this code and why does it not appear in GIMP?
What needs to be changed to make it work?
Code:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import os
import sys
from gimpfu import*
def test(timg, tdrawable):
print_to_stderr("Hello World")
def print_to_stderr(*a):
print(*a, file=sys.stderr)
register(
"test",
"test",
"test",
"test",
"test",
"2024",
"<Image>/Tools/test...",
"*",
[],
[],
test
)
main()

I want to draw perpendicular lines to a path within a selection. This can be done in gimp by selecting the right brush with the correct settings and then stroking a path with the the paintbrush or pencil. When I try to use the same settings in python-fu the stroked portion simply stays vertical. I have noted that during the manual stroke selection there is an "Emulate brush dynamics" option which is selected. I cannot find a similar setting in the python-fu api.
There might be some other issues in the script since this is my second python-fu script:
Code:
#!/usr/bin/env python
# GIMP Python plug-in template.
from gimpfu import *
def hay_selection(img, layer) :
gimp.progress_init("Finding next tree ring " + layer.name + "...")
# Set up an undo group, so the operation will be undone in one step.
pdb.gimp_undo_push_group_start(img)
# Do stuff here.
pdb.gimp_context_push()
# Base grey color
pdb.gimp_context_set_foreground(gimpcolor.RGB(224,224,224))
pdb.gimp_drawable_edit_fill(layer, FOREGROUND_FILL)
# Path around selection
pdb.plug_in_sel2path(img, layer)
np = pdb.gimp_image_get_active_vectors(img)
pdb.gimp_context_set_foreground(gimpcolor.RGB(0,0,0))
pdb.gimp_context_set_paint_method("gimp-paintbrush")
pdb.gimp_context_set_brush("2. Block 03")
pdb.gimp_context_set_dynamics("Track Direction")
pdb.gimp_context_set_brush_aspect_ratio(-20)
pdb.gimp_context_set_brush_size(15)
pdb.gimp_context_set_brush_angle(0)
pdb.gimp_context_set_brush_spacing(10)
pdb.gimp_context_set_brush_hardness(1)
pdb.gimp_context_set_stroke_method(1)
pdb.gimp_message("Dynamics: " + pdb.gimp_context_get_dynamics())
pdb.gimp_drawable_edit_stroke_item(layer,np)
# Fill interior with Hay Small
pdb.gimp_context_set_pattern("Hay Small")
pdb.gimp_selection_shrink(img,7)
pdb.gimp_drawable_edit_fill(layer, PATTERN_FILL)
# Cleanup
# pdb.gimp_image_remove_vectors(img,np)
pdb.gimp_context_pop()
# Close the undo group.
pdb.gimp_undo_push_group_end(img)
register(
"python_fu_hay_selection",
"Selection to Hay",
"Adds edge and fill to selection for hay.",
"jonker",
"jonker",
"2024",
"<Image>/Python-Fu/Selection to Hay...",
"*", # Alternately use RGB, RGB*, GRAY*, INDEXED etc.

Hi
When I call an existing plugin installed in my own plugin, how can I specify the "current folder", which is the folder the gimp file is in?
See "???"
pdb.python_fu_ofn_export_layers(timg, "???", "{numUp0}.png", "-", 0)

Hi
What exactly can the python console do in gimp and for what do you use it?
Is there any docs?
A small example of its usage would be great!

Good day to everybody...
I'm trying to call a G'MIC pluging from a pyhon-fu plugin with the following line:
pdb.gimp_run_procedure("script_fu_engrave", [image, layer])
The script I'm trying to call is:
(define (script_fu_engrave image drawable)
(plug-in-gmic-qt RUN-NONINTERACTIVE image drawable 0 0 "fx_engrave 0.04,40,0,2,45,-1,1,0,10,1,0,0,0,1,0,50,50")
)
(script-fu-register "script-fu-engrave"
"<Image>/Filters/Custom/Engrave"
"Apply the Engrave filter"
"Your Name"
"Your Name"
"2024"
""
SF-IMAGE "Image" 0
SF-DRAWABLE "Drawable" 0)
Script and plugin are into the right directories but the code return to me the following error:
Traceback (most recent call last):
File "C:\Program Files\GIMP 2\lib\gimp\2.0\python/gimpfu.py", line 741, in response
dialog.res = run_script(params)
File "C:\Program Files\GIMP 2\lib\gimp\2.0\python/gimpfu.py", line 362, in run_script
return apply(function, params)
File "C:\Program Files\GIMP 2\lib\gimp\2.0\plug-ins\GammaCorr1.py", line 66, in python_fu_custom_function
pdb.gimp_run_procedure("script_fu_engrave", [image, layer])
error: procedure not found
I spent a full day to try to fix it and I am very frustrated... Is there someone who kindly help me?

Hi,
I'm a beginner in the field. Please help me solve a problem. I have a 2500x3500px image, which I have uploaded in GIMP, to make part of it transparent. Then I wanted it to be downloaded with 300 DPI. Although I set the "Scale Image" to 300 DPI, when I downloaded it, I only had a 120 DPI image.
I made several attempts but to no avail, GIMP refuse to download the image at 300 DPI.
Where am I going wrong?
Thank you.

Hi
When you make a grid and then do a crop, the selection with the mouse snaps to the grid automatically when you reach a grid line.
Can this be turned off too?
