与分离器样式的Texturebrush

Question

需要一个Method来返回一个变量Texturebrush。该方法需要重载：

Size AreaSize,
int HorizontalSeperatorCount,
int VerticalSeperatorCount,
int SeperatorWidth,
Brush Seperatorbackground,
Brush Rectanglebackground,

矩形的大小将自动计算

这些示例具有以下值

Size AreaSize = new Size(100, 100),
int HorizontalSeperatorCount = 1,
int VerticalSeperatorCount = 1,
int SeperatorWidth = 10,
Brush Seperatorbackground = Brushes.Grey,
Brush Rectanglebackground = Brushes.Red

---

第二个示例具有不同的VerticalSeperatorCount

Size AreaSize = new Size(100, 100),
int HorizontalSeperatorCount = 1,
int VerticalSeperatorCount = 3,
int SeperatorWidth = 10,
Brush Seperatorbackground = Brushes.Grey,
Brush Rectanglebackground = Brushes.Red

---

方法的签名

public static TextureBrush GetTextureBrush(Size areaSize, int horizontalSeperator, int verticalSeperatorCount, int seperatorWidth, Brush seperatorBackground, Brush rectangleBackground)

Texturebrush将用于填充窗口

我不是最好的画画。 我对解决方案非常满意。

public static TextureBrush GetSeperatorBrush(Size areaSize,
    int horizontalSeperatorCount,
    int verticalSeperatorCount,
    int seperatorWidth,
    Brush rectangleBackground)
{
    var horizontalRectangleCount = horizontalSeperatorCount + 1.0f;
    var verticalRectangleCount = verticalSeperatorCount + 1.0f;

    var horizontalSeperatorBreadths = (horizontalSeperatorCount + 2.0f) * seperatorWidth;
    var verticalSeperatorBreadths = (verticalSeperatorCount + 2.0f) * seperatorWidth;

    var rectangleWidth = (areaSize.Width - verticalSeperatorBreadths) / verticalRectangleCount;
    var rectangleHeight = (areaSize.Height - horizontalSeperatorBreadths) / horizontalRectangleCount;

    var bitmap = new Bitmap((int)Math.Ceiling(rectangleWidth + seperatorWidth), (int)Math.Ceiling(rectangleHeight + seperatorWidth));
    var graphics = Graphics.FromImage(bitmap);

    var rectanglePoints = new[] { new PointF(seperatorWidth, seperatorWidth), 
        new PointF(seperatorWidth + rectangleWidth, seperatorWidth), 
        new PointF(seperatorWidth + rectangleWidth, seperatorWidth + rectangleHeight), 
        new PointF(seperatorWidth, seperatorWidth + rectangleHeight),
        new PointF(seperatorWidth, seperatorWidth)};

    graphics.FillPolygon(rectangleBackground, rectanglePoints);
    graphics.Dispose();

    var textureBrush = new TextureBrush(bitmap, System.Drawing.Drawing2D.WrapMode.Tile);
    return textureBrush;
}

因为四舍五入而对多个分隔符造成一些麻烦。对我来说没关系。
