示例1: Render
public void Render(Image image, Drawable drawable, bool preview)
{
int size = GetValue<int>("size");
image.UndoGroupStart();
var procedure = new Procedure("plug_in_pixelize");
procedure.Run(image, drawable, size);
var palette = new MinisteckPalette();
image.ConvertIndexed(ConvertDitherType.No, ConvertPaletteType.Custom,
0, false, false, "Ministeck");
palette.Delete();
image.ConvertRgb();
image.UndoGroupEnd();
// And finally calculate the Ministeck pieces
using (var painter = new Painter(drawable, size, GetValue<RGB>("color")))
{
Shape.Painter = painter;
int width = drawable.Width / size;
int height = drawable.Height / size;
var A = new BoolMatrix(width, height);
// Fill in shapes
bool limit = GetValue<bool>("limit");
var shapes = new ShapeSet();
shapes.Add((limit) ? 2 : 1, new TwoByTwoShape());
shapes.Add((limit) ? 8 : 1, new ThreeByOneShape());
shapes.Add((limit) ? 3 : 1, new TwoByOneShape());
shapes.Add((limit) ? 2 : 1, new CornerShape());

Action<int> update = null;
if (!preview)
{
var progress = new Progress(_("Ministeck..."));

}
var generator =
new CoordinateGenerator(new Rectangle(0, 0, width, height), update);
generator.ForEach(c => {if (!A.Get(c)) shapes.Fits(A, c);});
}
drawable.Flush();

}示例2: Save
protected override bool Save(Image image, Drawable drawable,
string filename)

writer.Write((byte) 0); // Fixed header
writer.Write(EncodeInteger(width));
writer.Write(EncodeInteger(height));
image.Flatten();
var rgn = new PixelRgn(drawable, true, false);
var wbmpImage = new byte[(width + 7) / 8 * height];
var buf = rgn.GetRect(0, 0, width, height);
for (int row = 0; row < height; row++)
{
for (int col = 0; col < width; col++)
{
int offset = col / 8 + row * ((width + 7) / 8);
if (buf[row * width + col] != 0)
{
wbmpImage[offset] |= (byte)(1 << (7 - col % 8));
}
else
{

}

if (((col + 1) % 8 == 0) || ((col + 1) == width))
{
writer.Write(wbmpImage[offset]);
}
}
}
writer.Close();
return true;
