Dividing a jpeg into a checkerboard of smaller ones?

[stevec]

I need to take two identically sized and shaped images (they happen to be labels) and divide them both into 48 smaller square pieces -- a grid 8 across and 6 down. I tried manually cutting the image(s) into rectangles and cutting and pasting, but its real hard to get the pieces to be the same size and I haven't even tried it for the second image! Please to help!

Thanks a lot.

1) Add a new layer.

2) Run this codelab script.

void Render(Surface dst, Surface src, Rectangle rect)
{

           PdnRegion selectionRegion = EnvironmentParameters.GetSelection(src.Bounds);
           Rectangle selection = this.EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt();
           int GridSizeX = selection.Width/8;
           int GridSizeY = selection.Height/6;
           ColorBgra CurrentPixel;
           ColorBgra PrimaryColor = (ColorBgra)EnvironmentParameters.PrimaryColor;
           ColorBgra SecondaryColor = (ColorBgra)EnvironmentParameters.SecondaryColor;
           bool Odd = false;
               for (int y = rect.Top; y < rect.Bottom; y++)
               {
                   for (int x = rect.Left; x < rect.Right; x++)
                   {
                       if (selectionRegion.IsVisible(x, y))
                       {
                           CurrentPixel = src[x, y];
                                   Odd = true;
                                   if (((x / GridSizeX) % 2) == 0) Odd = false;
                                   if (((y / GridSizeY) % 2) == 0) Odd = !Odd;
                                   if (Odd)
                                   {
                                       CurrentPixel.R = (byte)PrimaryColor.R;
                                       CurrentPixel.G = (byte)PrimaryColor.G;
                                       CurrentPixel.B = (byte)PrimaryColor.B;
                                       CurrentPixel.A = (byte)PrimaryColor.A;
                                   }
                                   else
                                   {

                                           CurrentPixel.R = (byte)SecondaryColor.R;
                                           CurrentPixel.G = (byte)SecondaryColor.G;
                                           CurrentPixel.B = (byte)SecondaryColor.B;
                                           CurrentPixel.A = (byte)SecondaryColor.A;

                                   }
                           dst[x, y] = CurrentPixel;
                       }
                   }
               }
}

3) Use the magic wand to draw a selection for one of the squares.

4) Crop to selection.

5) Delete the top layer.

6) File > Save as... to the filename of your choice.

7) Undo until the end of step 2 and repeat the process for the next rectangle - repeat until finished

Thanks a lot --but I do have to state my probable inability to carry this out. While I am 100% certain that this would work, and I greatly appreciate the quick reply, I wouldn't know where to begin entering these commands! My experience with Paint.net is limited to pretty basic cutting, cropping, resizing, a little bit of retouching and the like.....The common stuff on the menu bars....

So any further hints would be so helpful. I'm willing to learn -- just need a bit of help about where to start...

Thanks again,

Steve

Not sure if i can figure it out eider. But here are two useful links if you don’t know CodeLab.
