In this place we would like to post unfinished plugins made with CodeLab but which could be a source of inspiration for beginners.
I'll start with a fun(?) plug-in that can be further developed by those who want to do it.

Is there a way of formatting numbers so that unneeded zeros can be suppressed?
For example, the 0.0000 number to be displayed as 0 or 1.0000 to be displayed as 1.
Below I posted the code I'm working on.

This is an object alignment plugin made with CodeLab.
It's very slow for big canvases because of the algorithm.

It's very slow for big canvases because of the algorithm.

 

It could be made more efficient by determining the centering values only once.

  

bool firstTime = true;
int x1, x2, y1, y2;
void Render(Surface dst, Surface src, Rectangle rect)
{
	if (firstTime)
	{
		// find centering variables, x1, x2, y1, y2.
			.
			.
			.
		firstTime = false;
	}
		.
		.
		.
}

If the centering variables were possibly modified while being computed  (set to one value then another), I'd rewrite it or store them in local variables until the end, at which point I'd assign them to the "global" variables. E.g.:

  

	if (firstTime)
	{
		int locX1;

		locX1 = sLeft;
		if (locX1 > 100)
			locX1 = 100;

		x1 = locX1;
		firstTime = false;
	}

 

I don't think that's absolutely necessary, but it's the safe way. The reason is, it would still work if you take off the firstTime test. Otherwise with multiple processors, a thread could access a variable during the time a different thread had set it to the non-final value. The basic rule is that a "global" (class-level, really) variable must be the same for every thread, and can never be assigned anything except its final value.

 

BTW, what's with the dst[0, 0] =  dst[0, 0]? I don't see what it's for, but in any case, it seems wrong to assign to a pixel outside the ROI. I think it could conceivably cause a problem, also (assuming it's not optimized out).  A thread could load the 0,0 pixel just before the thread assigned to that ROI updates it, then store back the old value over the updated value.

I'd completely forgotten about this thread.

 

Here's something for y'all to play with. It's a little map generator.

 

Sorry about the long data section. I used to have more than one palette in there.

 

Note: Render it over a black background. If you want to exclude areas of the canvas, make them blue (you can soften the edge by blurring the blue edge).

 

This became the base of my RPG world maps;

 

DMs version (lots of extra info in the layers)

world_Map_A3.jpg

 

The version the adventurers get

Here's how the plugin UI looks, and a sample output....

The code....

@xod This plugin is very promissing. I just tested it and I liked it. 

 

There is one feature that I like and can be a great feature for this effect.

 

Look at my example : I made a "Top left" alignment for the apple at the top. Then I selected another area in the canvas and repeated the alignment (Ctrl +F) and the apple was correctly aligned in the new selection.

 

I wonder if the "Repeat alignment"  could be applied to several selections so that the apple would be placed in several selected areas and not just one. (the grid layer is just for a guideline).

I understand xod. Thanks anyway.

 

But if someone could figure it out would be a great addition to the alignment effects. When I need to align an object inside a selection I usually use MJW's  "Paste from clipboard" effect which will align whatever is in the clipboard. It does center the object inside a selection but it does not have other types of alignments though the object can be moved around.

Thanks @MadJik for compiling @Ego Eram Reputo 's mapper plugin.  Thanks for sharing the plugin EER!   :)

 

Can be used to create quick planets, also.  I left the original color, but the color could be changed easily.

I saw your reply & gave you +1 ;) I have no issues with you passing on the dll.

 

@lynxster4 This little mapper became the base for Planetoid - so what you're doing with it is exactly how I intended it to be used:  2D and 3D mapping.

This is my first plugin based on the Visual Studio Template provided by EER.

 

Its beautiful. I really like this. Well done xod.

 

Enhancements:

 

1. Any chance you could add some tool tips? I feel any control that doesn't explain its function with a text label should have a tooltip.

 

aligntooltip.png

 

2. Change the icon to gray with blue arrows, so it looks like your UI.

 

3. Add this into a new file called PDNSupport.cs (obviously change the red details to your own) 

using System;
using PaintDotNet;
using System.Reflection;

namespace TileWorld
{

    public class PluginSupportInfo : IPluginSupportInfo
    {
        public string Author
        {
            get
            {
                return "Scott Stringer aka Ego Eram Reputo";
            }
        }
        public string Copyright
        {
            get
            {
                return "© 2017 Scott Stringer";
            }
        }

        public string DisplayName
        {
            get
            {
                return "TileWorld";
            }
        }

        public Version Version
        {
            get
            {
                return base.GetType().Assembly.GetName().Version;
            }
        }

        public Uri WebsiteUri
        {
            get
            {
                return new Uri("http://www.getpaint.net/redirect/plugins.html");
            }
        }
    }

}

^^ That adds your plugin data to the tooltip when you hover on it in the pdn menu. At the moment nothing shows up.

 

This is an omission I've been meaning to add to the template. I've got it added, but haven't rolled it out yet.

 

To get it to work, you need to add a reference in your Align.cs file. Immediately following the namespace, add the new line... 

namespace Align
{
    [PluginSupportInfo(typeof(PluginSupportInfo), DisplayName = "Align")]

 

Results:

Technically, it goes on the line preceding the Effect class, as it's an Attribute decoration of that class.

 

Also, you don't need to use the constructor with DisplayName in it, as it can just get that from your implementation of IPluginSupportInfo. No need to type the name twice. :P

[PluginSupportInfo(typeof(PluginSupportInfo))]
class MyEffect: Effect
{

@Eli, you're right, but this plugin has a lot of problems.

 

1. If you use Magic Wand and select the entire canvas less the object and run an alignment the object is basically copied although nothing should happen.

 

2. If there are two objects per layer and one selection is created for one object and then a alignment is run, the other object will be brought in the selection.

I think the approach has to be completely changed and the code has to be rewritten from scratch.

 

EER, thank you for your suggestions and information.

@toe_head2001 - thanks for the info. I'll update the template. I might actually get to roll it out over my Christmas holidays.

Corner cases. Everyone misses them when they're starting out :mrgreen:

You need to blit the relocated selection object onto a copy of the source layer which has had the selection object erased. What you're describing sounds like you're moving the entire layer based on the location of the target object.
