Request: Point of origin = center

[Hellfire010]

I was wondering if it is at all possible to make the center of your picture x=0, y=0, and it goes out from there. I would find it much easier to draw things on an entire coordinate plane than just the one quadrant. This is simply for the little x/y indicator on the bottom right. just a little favor, I hope it can be done.

[Picc84]

How would you label diagnal form the center?

[Hellfire010]

What do you mean? like (5, 5), (-5, 5), (5, -5), and (-5, -5) (for example)? Just like that.

Its basically the same thing as it has now, but it would just make find distances from the center a lot easier.

[Illnab1024]

No, this is the way it has always been in image processing, and it ain't changing.

[crosswalker]

um...Illnab, I understand your point, and you're probably right, but just because something's "always been" doesn't mean that it always will be.

[Illnab1024]

It is the most universally understood method of defining it, and the most logical. I'm just saying...and I meant it ain't changing on PdN, I'm pretty sure...

[Hellfire010]

My suggestion was a possible change, as in an ability to toggle between the two. At the very least, a plugin to make it so. Doesn't have to be officially with PDN.

*crosses fingers*

[TommyCarlier]

I actually like the idea. Makes it a lot easier to align stuff, to find the center of the image. And not only for the x/y indicator on the bottom right, but also for the rulers.

Remember Paint.NET can be used for other stuff than just photo editing.

[Hellfire010]

Yeah, forgot about the rulers

And also, Illnab1024, I was suggesting it as an addition, not a change. I guess that's better wording for it.

[Rick Brewster]

Sorry, this won't be happening. And it is not possible with a plugin.

[RaveN]

If I am not mistaken, there is an option to put in a grid for it, or always make a new layer, and set the line to 1 pixel, and map out the quadrants.

[Hellfire010]

Well I'd be better off finding the center than mapping it out every time. Thanks anywho...

[RaveN]

Make documents that are like 450 x 150 and so on, and it is quite easy to find the center..

[Hellfire010]

Not just the center I need, but yeah... doesn't matter now.

MAYBE there can be an option to "Center selection horizonatlly" and "Center selection vertically" ???

[RaveN]

Artisticly speaking ( you caught one of my rare typos where I dont know how it is spelled ), the concepts of design and composition of good art isn't originating at the center.

Make a tic tac toe grid, the middle 4 corners are the points of focus

Where the red dots are located are the focus points, or they can make an

L , _ , or | and be aligned like so, other shapes can be made, like that, but you see what I mean hopefully.

Just a tiny quick art lesson for you.

With your sig, I would say the main focus is the mans arm and bow, which lie across the bottom line of focus, and the bow goes up the right vertical line of focus....Which is elequently composed, I like it.

[Hellfire010]

Thanks

But, the reason I may want to center something, for example, is if I would like to use a radial blur to round up a circle, or something of that sort. Another solution is having the ability to use the center of your selection to be the center of an effect. Currently, no matter what you have selected the center is always the center of the entire piece.

If you need help making grids, here is a codelab script:

void Render(Surface dst, Surface src, Rectangle rect)
{
   int GridSize = 10;
   bool AlphaOnly = false;
   bool ForegroundOnly = false;
   bool SwapColors = false;

   PdnRegion selectionRegion = EnvironmentParameters.GetSelection(src.Bounds);
   Rectangle selection = this.EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt();
   ColorBgra CurrentPixel;
   ColorBgra PrimaryColor;
   ColorBgra SecondaryColor;
   if (SwapColors) {
       PrimaryColor = (ColorBgra)EnvironmentParameters.SecondaryColor;
       SecondaryColor = (ColorBgra)EnvironmentParameters.PrimaryColor;
   } else {
       PrimaryColor = (ColorBgra)EnvironmentParameters.PrimaryColor;
       SecondaryColor = (ColorBgra)EnvironmentParameters.SecondaryColor;
   }
   for(int y = rect.Top; y     {
       for (int x = rect.Left; x         {
           if (selectionRegion.IsVisible(x, y))
           {
               CurrentPixel = src[x,y];
               if ( ((x % GridSize) == 0) || ((y % GridSize) == 0)) 
               {
                   if (!AlphaOnly)
                   {
                       CurrentPixel.R = (byte)PrimaryColor.R;
                       CurrentPixel.G = (byte)PrimaryColor.G;
                       CurrentPixel.B = (byte)PrimaryColor.B;
                   }
                   CurrentPixel.A = (byte)PrimaryColor.A;
               } 
               else 
               {
                   if (!ForegroundOnly)
                   {
                       if (!AlphaOnly)
                       {
                           CurrentPixel.R = (byte)SecondaryColor.R;
                           CurrentPixel.G = (byte)SecondaryColor.G;
                           CurrentPixel.B = (byte)SecondaryColor.B;
                       }
                       CurrentPixel.A = (byte)SecondaryColor.A;
                   }
               }
               dst[x,y] = CurrentPixel;
           }
       }
   }
}

Thanks but... I don't need help making grids.

Idk how to use the codelab anywho.

[BoltBait]

Well, if you ask nicely, Illnab1024 will put a UI on it and make it REALLY easy to use.

[Hellfire010]

Illnab1024

*puppy dog eyes*

(wait... what's a UI, lol)

[BoltBait]

UI = User Interface.

Basically, it is the dialog box that asks you questions like, grid size, etc. then applys the effect when you press the OK button.

It also includes things like the icon and name you see in the effects menu.

EDIT: OK, Illnab1024 finished putting the polish on it. You can download the effects dll here: http://paintdotnet.12.forumer.com/viewtopic.php?t=2302

[Hellfire010]

Alright, thanks to the both of you.

Edit:

WOW its perfect, THANKS! xD
