| dynamics not working in gimp-drawable-edit-stroke-item |

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)

"python_fu_hay_selection",

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?

Hello all and thank in advance for your help with this unusual issue! I have been using Gimp for a very long time with no issues but recently whenever I create a selection using the fuzzy select tool and use the delete key to rub it out, I find that the remaining parts of the layer go semi-transparent. Can anybody tell me how to prevent this please?
Thanks!

I use ofn-export-layers a lot. Super useful plugin!
I noticed a very strange thing in windows 10 , GIMP 2.10.36
When ofn-export-layers is running (writing files) and I enter text anywhere on my computer, it adds characters I don't enter on my
keyboard like: ~ and ' and many more. So if I write "test", it adds random character in "test" which I dont really enter...
When ofn-export-layers has finished, this strange thing dissapears and I can enter text normally
Also ofn-export-layers runs very slow. Is this related to this?
I wanted to ask if the developer can tell me what this problem could be and if ofn-export-layers can be made faster (if possible).
So I need to wait to enter text anywhere until ofn-export-layers finished his work.
