Why not use the grid maker plugin: http://forums.getpaint.net/index.php?showtopic=4175
- on a transparent layer with foreground only checked. Then use it as a guide to line up your objects?
I think a snap to grid plugin could be very decieving as the anti-aliased pixels around an object mean that edges are not always where they seem to be. So for it to look correct you would need a fine adjustment - so you may as well do it the long way I've suggested and decide if it 'looks' correct.
Have you tried the align object plugin ? : http://forums.getpaint.net/index.php?showtopic=4193 -
Hello NMD,
There are many that do something similar - did you mean this one?

That looks interesting Midora, particularly 'Tabs'.
'LabelMin' and 'LabelMax' would certainly make it easier to align the words correctly and I like the option to show units too.
I have a few ideas that may or may not be sensible (I simply don't have the knowledge yet to know how difficult or practical these things are to do using a customU.I.).
1. I find the 'reset to default' buttons for the trackbars very useful. There doesn't appear to be this function for the checkboxes, drop-down lists or radio buttons - perhaps there could be one 'reset all to default' button for all the controls?
Aha! - I've just noticed you have included this for checkboxes in your example.
2. I find the drop-down lists very useful as they save a lot of space on the U.I compared to radio buttons. I wonder if there could be a drop-down list of ckeckboxes too?
3. Possibly an 'Info' button to show a message box where the plugin author can write basic instuctions?
Just thought I would suggest these in case they have not already been considered.
The OptionBased library looks very promising! - thanks for posting the example.

Perhaps this may be relevant too?

^^Wow! - thanks
- and many thanks to Null54 for making it possible too! 
And Pixey - I think I used to have a 'candlewick' bedspread with that texture - (all duvets these days) - thanks for posting.
-
Trackbar labels: - Yes, much as EER says.
I do try to make the UI tidy and logical, but explaining the function to the user takes precedence. Also, personally, I find breaking up the visually uniform look of a 'wall' of trackbar sliders makes it quicker to find the one I want. -
Daniels - please do - I find simply 'playing' with plugins the best way to learn and discover new techniques.
EER - I should nominate that to the Galeria (but there could be copyright issues) - it does make me chuckle!
YM - stunning! - great use of the plugin and the image itself is a pleasure - great colours & textures!
Dug - looking forward to seeing what surreal uses you find for it.
Pixey - That looks great! - original use of Furblur for the icicles. 'Clever' - I wish! (Null54 is the clever one for getting it working).
Helen - you can hug me anytime! - looking forward to seeing your results - perhaps some candyfloss trees for your candy house?
Good to see what you're all creating.-

Thank you!
I think I will be refering to your explanation many times;-) -

Hi Null54,
Imagine a preset called say 'very large curls' created on a standard 800 by 600 canvas.
The user next uses this preset on a 1600 by 1200 canvas and eventually sees a very small curly texture.
The effect the user sees is very dependant upon the selection size.
I think the presets idea would be more relevant for a 'Render' effect where the size, especially line width, can be related to the selection size. If FurBlur had used GDI+ to draw the lines it would have been relatively easy to change the line width based on selection size. But then it would be a different effect.
Thanks for the example XML - I can see presets being useful for other effects but not really convinced it is needed for this one.
Do I understand correctly, XML presets could only be used with a Windows Forms based effect (or the 'OptionBasedLibrary' in the future) but are not possible with the current IndirectUI?
Sorry for my confusing explanations!

Aaaah - too many people to thank - you're posting fasting than I can type!
TR - Thanks for the support on this one and brilliant images too!
BB - Thanks - it started life in codelab!
EER - Thanks for all the VS tips and encouragement too.
doughty - glad you reposted the prevoius 2 and the furryworm is great!
BBQ - hope you are getting decent results now.
WB - love the Obama one!
Drew' - Thanks for reposting Fircraft and hairy target and adding the clipwarped one too.
Oceana - That's given me vertigo!
NN - Cheers - you know me too well!
Should be ok to use on layer after 'Curly Line' - If using Furblur repeatedly on the same object layer you may need to lower the 'Start object transparency' slider a little. That's because it is a blur and mixes the opaque object with the transparent surrounding pixels.
To all - many thanks all who tested and have reposted or added new examples. Glad you seem to be having fun with it and many thanks to Null54 for getting it to work!-

Midora - the OptionBasedLibrary sounds very promising!
TR - Thanks for the example code and .dll - I can just about get the idea of how it works. It could be a useful technique for future plugins. (Update: Midora has just posted - so, still interesting but looks like the long way is best - many thanks anyway)
Regarding presets or user saveable settings for FurBlur, I'm not sure it would make the effect any easier to use or understand. Because it is a blur on a pixel size scale, any preset would look very different on different selection sizes. If it was a GDI+ based render effect, then the preset sizes could take selection size into account - and presets would be a better idea.
I have used a drop-down list and switch block before, to make presets that change the way the control values are used (or ignore them). (e.g. 'Highlight' and 'Object2colour'). - Haven't tried anything saveable though.
I tend to think some users will want a plugin to work perfectly with the default values and others are happy to explore all the controls to get the effect they want. I'm not sure the first type would be bothered to create and save settings and the second type possibly wouldn't need to?
For Effects more generally, I tend to either use an effect with different settings each time or consecutively run the same effect with same 'auto-remembered' settings. If I really need to record exact settings for a plugin I write them down - (useful equations for 3D Object plugin for example).
So, I don't intend to add presets to Furblur but will consider it for future plugins. Many thanks for all the suggestions and info though. Some of it will sink in eventually!

Furblur update 30th July 2014
A versatile blur/trail effect. Useful for Fur, false beards and grass textures and also for paper textures, watercolour effects and 'scribbled' drawing effects.
Found under: Effects/Blurs/FurBlur Dll name = FurBlur.
An updated version is in my V10 Plugin pack hereRed ochre v10 plugin pack
I would like thank 'Null54' who made this plugin possible. I spent days trying to get it to work and he solved the problem in hours! - greatly indebted. I would also like to thank EER, without whose diplomatic skills I would have left the forum months ago. Finally I must thank the many people who tested this for me over on developers central - the difficulty with random effects is that the bugs can be quite random too, it appears. So many people testing has been very useful.
I am updating Furblur. It still works in much the same way on default settings, but I have added some more 'fun' stuff.
Changes:
1. I wanted to make some feathers and needed more control over the curl direction, so have added this.
2. Started running out of U.I. space, so put these new curl choices in a drop-down list with the direction choices.
3. Took the liberty of removing some of the titles to the drop-down boxes - again to save space.
4. Have removed the colouring choice - now it only colours along the fur. (The fur can easily be recoloured later if the 'only keep fur' box is checked).
5. Have improved the antialiasing.
6. Have slightly increased the speed.
7. The fun bit - have included 12 new curl shapes.
8. Changed the icon pussycat colour to ginger - so you can easily tell which version you have!
HistoryHidden Content:v1 = 459 downloads
As before, best to experiment as described below - the UI has changed but all the previous examples are still possible.
Here is the new U.I. and example curl shapes:
How to use:
Be very wary of using the plugin on large selections with large 'reps' or 'length' as it will be very slow!
I suggest you try the plugin out in the following way, just to get an idea of how it works.
1. New image 800 * 600 - make background black.
2. New layer (transparent)
3. Draw 10 pix wiggly lines. nice bright colours
4. Possibly select around these lines with the lasso tool (leave plenty of room for the effect!)
5. Effects/Blurs/Furblur - lower the 'rep' slider and increase the 'length' slider to start.
6. Try each slider seperately to see what they do.
Hopefully the following images will give you some ideas. Please feel free to post your FurBlur images in this thread and any tips you have discovered. Enjoy!

Nice work Oceana! - glad the instructions helped.
EER - just about to publish - perhaps we can work on the XML idea for future updates.
All - you've made some good images here - please feel free to repost them on the published FurBlur thread. Thanks for testing!
-
TR - love it!
EER - That is a good idea - I must admit I haven't got a clue where to start though and have never used that Shape3D option. If you would like to help me, I/we can either delay publication or add this as an update later?
I would favour publishing sooner - so people have a proper thread to show all these great images.
YM - great fun!
BBQ - I hope you are getting decent results now - if not, please post back. I am useless at explaining things (not great at understanding sometimes either!).
WB - I'm hoping this will be useful for textures and chromatography/watercolour type effects as well as photo-manips (which are great fun!).

^^ Haven't yet - have seen the trailers - waiting till it comes on the TV! (too 'tight' to buy)
Tiger on a boat - they love to swim! + how are they at navigation?

- Just typed a long reply BBQ - then bashed the mouse and I've got to type it all again!
Ok. Best not to use on all of a large canvas to start with.
The calculations are run single threadedly - so none of the speed advantages of a powerful machine.
I suspect the little lines are the effect - it operates on a pixel size scale so may be hard to see on a huge canvas.
Suggest to test:
1. New image 800 * 600 - make background black.
2. New layer (transparent)
3. Draw 10 pix wiggly lines. nice bright colours
4. Possibly select around these lines with the lasso tool (leave plenty of room for the effect!)
5. Effects/Blurs/Furblur - lower the 'rep' slider and increase the 'length' slider to start.
6. Try each slider seperately to see what they do.
If still no joy report back please!
I am working on getting some examples together at the moment with screenshots.

No crashes yet then ? good! - thanks all for testing and positive feedback. I will publish it properly soon.
doughty - I really like that one. Interesting 'grunge' texture + the 'curve variation' slider way up = looks good!
Drew - another good result! - that aeroplane needs a shave! - thanks for checking this one out.
TR - Thanks for the compliment - knowing your programming skills I am very flattered!
Regarding presets: I don't intend to add them - partly due to my laziness and also because I would rather users 'play' with all the controls to get an idea of what this can do. I generally like to give users as many options as practical but I know this can sometimes make the U.I. a bit intimidating. I will include some example settings and results in the publishing thread but hopefully users will experiment and come up with new uses.
That tiger has walked a long way!

I am attaching the newest version of Furblur for testing. I've added quite a lot including the circular option for the curve, which gives much better results. However, I like the previous, slightly dotted (spiral) version as it can look like grass seeds, so am keeping that option.
Now doesn't mix the colour with the transparent white!
Added a slider to choose the transparency threshold of an 'object'. At around 250 will only put fur on 'objects', at 0 will work on whole selection (only seen if colour turned up).
Speeded up slightly too.
Changed radio buttons to checkboxes to save space.
I would be grateful if you can give it try and report any crashes. There shouldn't be any - but I thought that with the last one! - Many thanks

I see you are all coming up with good uses for this! Thanks for the encouragement and enthusiasm.
Cool image Drew.
Love the ZZtop one Sasha - I think the drummer is called Frank Beard too!
TR - Grass effects are definitely one of the uses I had in mind for this one.
I'm still working on this one - the 'beta' above will crash occassionally (sorry) - so, if testing, always save everything before running it. Thanks Welshy and Doughty for testing.
Hopefully I will get a better (stable) version finished soon.
Cheers all
(just seen Doughty's American gothic - subtle but funny! - good work)
Sorry Mottoman - Only just seen yours too - good work - I think we should have a bearded lady comp once this plugin is finished!
A few of my tests:

Hi Welshy,
Thanks for reporting that - It happened to me just now - I think I've fixed it (hopefully) - It uses a lot of random numbers between a maximum and minimum, and somewhere the minimum was larger than the max - computer says no!
Also working on varying the amount of curvature randomly and blending in the Primary Color in a more interesting way + some other ideas.
Nice pic!
Have got some good results just running it on a 20pix paintbrush line (on transparent layer) with 'Only keep fur' checked.
@ Null54 - thanks for that tip - I may be changing some of the controls - will bear this in mind.
@ EER - thanks!
@ Pdnnoob - monsters are great!
-
That's cheating! - I rely on 'lucky' words.
I find maths far more interesting if I can see what it's doing - I'm actually starting to understand some of the maths I was supposed to have learnt 30 odd years ago.
It's also good to see how much can be achieved with so few lines of code. -
Nice work - how do you write them so fast?!
-
I love my furry balls too!
It's going to be difficult steering away from the inuendo when I publish! - trouble is it sounds even worse as hairy spheres?

Hi Pixey - nice work on the new sig!
Love the grapes, vine leaves, apple and mouse.
(- bit confused as to what that is behind the mouses head in front of the apple - tail? tendril?)
Rest of it looks great though, and your gallery works perfectly and loads quickly too!
(often a problem on other galleries - with my sluggish broadband).
