Thankyou Lyle and B&P I guess I'm a right click person since losing the use of My left arm but I'll adapt and re-educate myself. :yes

You can delete or rename formula_viewer.pyw so it doesn't popup. Plugin will work without it.

without formula viewer the plugin menu does not appear for some reason

It should and does work here without the formula viewer. Just try renaming it and see if it works.

I renamed but no menu appeared, I can close the viewer after menu comes up, but deleting or renaming both formula viewer locations prevents the plugin menu from appearing.

Personally i think having the previewer is pretty nice. Closing and re-opening the vector path dialog over and over to see results would kind of suck after a while.

I've been working on upgrade for Formula Viewer app, and I would like to ask you guys to help me test before I announce it and include in the main download package on my site. So here it is.

Attachment:

Formula Viewer v1.2 Beta.zip [3.21 KiB]
Downloaded 144 times

New features:
Added Name field.
Added Preset selection list box.
- Use Up/Down Arrows to scroll through the items
- hit ENTER to load selected preset [STILL BUGGY]
- auto scroll to item by typing first letter [STILL BUGGY]
Added Load/Delete/Save preset functionality.

if formula_presets.csv doesn't exist, it is created in the same directory as the viewer script.
I am including my presets file for your convenience.

Note:
The vector path plug-in has maximum limit for the number of points - 1000.
However, some complex paths (like the one below) require much more than that.

I will eventually update my code to allow larger number of points, but for the mean time, if you do need this: edit line 217 in the b&p_vector_path.py:

Code: Select all

(PF_SPINNER, "num_points", "Number of points:", 500, (2, 1000, 1)),

to read something like:

Code: Select all

(PF_SPINNER, "num_points", "Number of points:", 500, (2, 1000000, 1)),

Hope for your feedback.

Excellent plugin !
For me, it works very well (Gimp 2.8, Win XP32, Python 2.7.1).
Now it's time to play with the settings ....

Very nice!

Thanks for adding the save presets option to this.

It works excellent for me also in Gimp-2.8-Portable-Windows XP 32 bit OS.

Thanks again!

Testing in Gimp-2.8 install now.

Gimp-2.8 install - running excellent.

I noticed when i save a preset it saves it with the same name as other presets?
I named one Rod's angular diamonds and it saved it as Angular net 1.

Can i just change this in the csv file?

Rod · **Joined:** May 16, 2010 **Posts:** 16011

This actually saved in the csv file as Diamond 2 :lol

Dunno how that happened but it doesn't show as that name in the presets.
This must be that bug you talked about earlier?

Hi Rod, can you share your csv so I can test. yeah, there are a few bugs still.
Thanks

Edit: Never mind, I saw the problem.

B&P thankyou for adding the presets they work a charm :coolthup

Guys, I am working out a few ideas and might add a few features to the script.
Perhaps this is off topic, but I am facing a problem with brush strokes. I am trying to make an animated brush with dual stroke (similar to my example images), but I cannot make it smooth. is it possible at all? Any help would be greatly appreciated.

I used ribbon path by ofnuts to do this

you can get it here http://sourceforge.net/projects/gimp-path-tools/files/scripts/ribbon-path-0.1.py/download

This is easier than creating special brushes

Here is a great tutorial on creating animated brushes using GAP... Gimp Animation Package.
http://www.gimptalk.com/index.php?showtopic=21334

This may help you to create a smoother looking result.
Basically bigger to start is better, then scale it down to the size you actually want. This usually makes for a smoother rotating brush.
If you need the GAP package for 2.8 holler at me via PM.

Thanks for the view update and code change suggestion B&P. Only now getting around to implement this (meant to do so several days ago). Works in 64-bit GIMP 2.8.

Why do you have a 32 folder in there?
GIMP 2\32\lib

I have never seen that before.
Is there also a 64\lib folder?

no - its the 32 bit folder for Gimp 2.8 on Windows 7 64bit
Gimp have it installed

I can use 32bit Plug-Ins and 64bit Plug-Ins

It's a 64-bit GIMP feature Rod. It is what allows 64-bit GIMP to run 32-bit plugins.

It's a 64-bit GIMP feature Rod. It is what allows 64-bit GIMP to run 32-bit plugins.

Is that in the official Gimp.Org installer? Or is that Parthas compiled version?
