[Unfinished plugins]

This plugin allows you to write text along a curve.
There are only four control points.
The plugin is located in Effects -> Text Formations.

As usual, you need the two OptionBasedLibrary v0.7.9.dlc and OptionBasedLibrary v0.7.9.dll files.

I used with slight modifications the method that @Pixey indicated.
It is an example of a fast execution without tweaks. For example, the tie shows the flower petal in the original image.
Sure you can save the image without any problem, but I think it's best to process it yourself.

 

[Moving People In Photos Closer Together]

You need something like that?

[Background removal]

I always use this method:

 

 

[Effect Dialog Window in Center of Screen (Resolved)]

On the plugins created with OptionBasedLibrary it is allowed to remember the location where the window is displayed:
Menu -> Remember Location
Too bad the development of this library has been abandoned.

The code below provides information about the object on the canvas.
It seems to work correctly in all situations where the object is on a transparent layer and even if the layer is full of color.
However, if I have an filled area of 10000x7500px and even for smaller values of the surface containing a transparent vertical strip as in the image below, the error 'A new guard page for the stack cannot be created' appears and Pdn crashes.
I can't figure out how to solve this.

[2 point perspective text?]

You must to split the text in 2 section before run Trail.
1. Run Text Distortion into one empty layer an type ..........KAT (10 dots before)
    the setings is:
]

2. Run Text Distortion into another one empty layer an type LEEN..........(10 dots after)
    the setings is:

3. Cut the dots into the both layers using Rectangle Select tool
4. Outline the text 1 pixel
5. Run Trail plugin in the KAT text layer with default settings and uncheck Fade out
6. Run Trail plugin in the LEEN text layer, change direction to 180 degree and uncheck Fade out
7. Merge layer down

I updated the Align + plugin. See the first post.

[Unfinished plugins]

Okay, I understand that people don't really use the official version (Align Object) because it's in the Object submenu.
So, I changed the name of the .dll

[Unfinished plugins]

@Seerose, to answer you I need more information.  Be more specific.

[Unfinished plugins]

That shouldn't happen.

For testing I placed it in the Object submenu.
In my case, the new plugin does not overwrite the existing one.
You probably have a different version of Align Object than the official one.

 

[Unfinished plugins]

This is an experimental plugin.
You need the two OptionBasedLibrary v0.7.9 files.

You can place it where you want by editing the Align+.dlc file.
In order to do that you need to change the extension to .txt

Open it with Notepad and edit the line:
AlignEffectPlugin.SubmenuName=your choise
Save and change the extension to .dlc

You can try Kris Vandermotten plugins.

What a shame. I liked the new features of renaming the AmountX variables.
I wonder if it's possible to do the same thing with the RadioButtonList or DropDownList options so that using 'switch variableX' we can use 'case variableX.name:' instead of 'case 0 :, case 1:' etc.
