New plugin: Rhodonea |

Another offshoot of the Parametric curves. Draws rose-like figures.
To get the plugin, go to
http://kmarkku.arkku.net/
follow the link 'Applications', and click the second Download button there. That gives you a .zip file. Unzip it, put the .py file into your Gimp's plug-ins folder, and restart Gimp. The plugin 'Rhodonea' will be in
Filters/Render/Parametric curves/Special cases
If there are any problems, please tell me.

Can only click on some things??? |

For whatever reason only certain buttons are clickable...
I can click 'open new project', and i can move around through the folders in the left side bar, but clicking on any of the images doesn't do anything.
Clicking cancel, or 'X' to close the dialogue box also does nothing.
The only way out of this menu is the 'escape' key or 'alt+f4'
I can select some tools, some simply don't respond to being clicked on, i can't actually use the tools though, the clicks on the open image with a tool selected don't do anything.
i can open images by right clicking them and opening with GIMP just fine, but can't edit them because I can only select some of the tools, and once I do my clicking no longer registers and I need to open a new instance of GIMP...
Any ideas what the heck is going on?
EDIT: I Should add that I've been using the program just fine for some time now, it suddenly decided that half the buttons do nothing just today.
I ran GIMP in verbose mode to try and figure out whats causing it to bork up, and now its working fine again.
after multiple computer resets, opening and closing GIMP 1,000 times not helping at all,
It's suddenly back to normal. ¯\_(ツ)_/¯

New plugin: Spiropath |

I got the feeling that the general-purpose plugins Parameter curves and so on do not raise much enthusiasm. They are mathematical, and my experience is that the mere word mathematics tends to put people off.
So I thought that it might be good to derive from them some specialized plugins. The first one is now available: it draws spirographs.
According to wikipedia, 'spirograph' is a registered trademark. Perhaps I am too sensitive, but I decided to call the plugin 'Spiropath'. It draw spirograph-like curves as Gimp's paths (approximations).
Gimp already includes the plugin SpyroGimp, which I guess comes nowadays automatically when Gimp is installed. But it does not output paths.
I found an old plugin
https://gimper.net/resources/spirograph.624/
that creates paths. But it seems to rely on placing control points densely on the curve. It does allow the user to diminish the number of control points, but then it turns out that between two successive anchors it simply puts a straight line segment.
My plugin outputs a path with a sparse set of anchors, yet it is reasonably accurate. So, it seems that nothing similar exists previously, or am I too optimistic?
To get the plugin, go to
http://kmarkku.arkku.net/
follow the link 'Applications', and click the Download button there. That gives you a .zip file. Unzip it, put the sole .py file into your Gimp's plug-ins folder, and restart Gimp. The plugin 'Spiropath' resides in
Filters/Render/Parametric curves/Special cases
That is a long path, but I don't want to add more items in Render, and I want to separate the special curves from the three general curves. I plan to put there a couple more soon.
A drawback of the plugin is its size: over 5000 lines. I constructed it by putting together most of parametric_curves.py and the example file which draws a spirograph and then developing things a little further.
I hope you will enjoy. At least the curves are pretty.

GEGL Operations Freezing Gimp? |

So here's the problem. When I go to use a GEGL operation like Color to Greyscale Conversion The program ether will do it but will load the preview one block at a time and freeze in between blocks and take several minutes to finish or just freeze entirely and not work depending on the settings I have (and this image is 1500x1000 pixels). Only Gimp stops responding I can still use all other programs.
I've Googled around and people say RAM RAM RAM. Well see I have an i7 6800K and 32Gbs of DDR4 RAM and my tile-cache is set to 26Gbs. I also have a GTX 1080. Oh and it's running on an M.2 NVME SSD.
So I'm trying to figure where the bottleneck is. Gimp? My hardware?
Maybe I'm not understanding the complexity of the operation.
Any help is appreciated.

How to get error messages in plugin registration? |

I am on Windows 10.
I remember having seen how to get error messages from registration of a Python plugin, but I don't find it. (I guess it was on Gimp-Forum.com?)
I am making a plugin. It runs ok in the console. When I try to registrate it, I get no error messages but it does not appear in Gimp's menu. When I feed the registration part (without the main()) in the console, no syntax errors are found. I cannot see any faults in the code.
This situation has happened many times in the past, and every time it takes a long time to find the errors without any help from error messages. So, please, tell me how I can get the error messages, and the simpler the method the better.

How do I edit the ways I can change the size of the tools? |

This is a very difficult question to explain cause I have no idea what the terms are, but basically, you used to have two slider options when changing the size of tools. One where you could slide and it would stay with your pointer, and another where you would slide and it would go at a slower, steadier rate. This was removed in the most recent version of gimp and I was wondering if it's possible to enable it?

Precision: 8, 16 or 32 bit? |

Hi,
I was trying to use the RGB equivalent of a specific CMYK, namely 4,100,95,0 (RGB = 244,8 0,0 12,8; #F5000d).
However, although I selected this color (# F5000d) the result when checked was always #F5000c; RGB 245.0 0.0 12.0
Even at http://paletton.com/#uid=75B0u0kw0vijNCzp8xHytouDMjd when I entered the code #F5000d, the code #F5000c was automatically assumed.
I struggled with this limitation for some time until I finally looked for a solution.
This happened by chance, when doing experiments I changed the precision from 8 bit to 16-bit integer and voilà.
With that precision, I was able to select the color #F5000d and now the Color Picker Tool recognized that color. (Although the RGB slightly different 245.0 0.0 13.0)
I am not aware of this precision issue (Image - Precision - x bit)
Does choosing between 8 bit, 16 or 32 results in some type of higher memory or processor consumption?
Can I select the option 32 bit (or 16 bit) without any fear of any unknown consequences?
In general what reference should I take to find out what is the best precision that best suits my use?
Thanks in advance!
