伙计们

我被要求解决一个问题-与此处发布的问题相同；

Hi Guys

I have been asked to solve an issue - same as the one posted here;
http://social.msdn.microsoft.com/Forums/da-DK/csharpgeneral/thread/e285e4d9-c43d-4482-a2e7-c8d1861657e0[^]

I have managed to get the rectangles up and displaying, the problem i am having is when i try to get them all on one touching and NOT overlapping -
if i manually add 3 RANDOM rectangles i can get 2 of them to look perfect, the last will appear in random and overlapping.

If i manually set the properties of the rectangles, i can accomplish what i am wanting - hence, the confusion;

The below code works;

rectangles = new List<rectangle>();
            Rectangle rect4 = new Rectangle(10, 160, 100, 100);
            Rectangle rect5 = new Rectangle(rect4.X + rect4.Width, 160, 120, 120);
            Rectangle rect6 = new Rectangle(rect5.X + rect5.Width, 160, 100, 140);
            Rectangle rect7 = new Rectangle(rect6.X + rect6.Width, 160, 100, 80);
            rectangles.Add(rect4);
            rectangles.Add(rect5);
            rectangles.Add(rect6);
            rectangles.Add(rect7);
            
            graphics.DrawRectangles(pen1,rectangles.ToArray());

但是以下循环不会；

Yet the following loop doesn''t;

Rectangle foo = GetRandomRectangle(rng);
            Rectangle bar = GetRandomRectangle(rng);
            Rectangle car = GetRandomRectangle(rng);
            List<rectangle> rectangles = new List<rectangle>();
            rectangles.Add(foo);
            rectangles.Add(bar);
            rectangles.Add(car);

foreach (Rectangle rect in rectangles)
{
if (rect.Height > TallestRectangle) { TallestRectangle = rect.Height; }
}
foreach (Rectangle rect in rectangles)
{
if (PreviousRectangleX + PreviousRectangleWidth == 0)
{
graphics.DrawRectangle(pen1, new Rectangle(rect.X, (TallestRectangle - rect.Height), rect.Width, rect.Height));
}
else
{
graphics.DrawRectangle(pen1, new Rectangle((PreviousRectangleX + PreviousRectangleWidth), (TallestRectangle - rect.Height), rect.Width, rect.Height));
}
PreviousRectangleX = rect.X;
PreviousRectangleWidth = rect.Width;
}

函数GetRandomRectagle;

Function GetRandomRectagle;

private Rectangle GetRandomRectangle(Random rnd)
        {
            int x = rnd.Next(4, 110);
            int y = rnd.Next(4, 110);
            int width = rnd.Next(4, 110);
            int height = rnd.Next(4, 110);
            Rectangle rec = new Rectangle(x, y, width, height);
            return rec
        };

任何帮助将不胜感激?

问候

Any help would be greatly appreciated?

推荐答案

您似乎没有将TallestRectangle设置为任何值-我会尝试在外循环之外将其初始化为负值.

You don''t appear to set TallestRectangle to anything - I would try initializing it outside the outer loop to a negative value.

更新:
我设法按需要绘制了矩形，我现在正在为它们全部实现循环，这样可以随时通知您.
谢谢.

Update:
I have managed to get the rectangles to draw as wanted, i am now in the process of implementing a loop for them all, will keep you posted.
Thanks.

跟上这篇文章，我一直在思考实现这一目标的最佳方法；
生成所需数量的矩形并将其写入文件(以人类可读的方式.)
从上述步骤中生成的文件中读取随机生成的输入矩形"

我已经使用bmp/jpg文件完成了第一步(即，我保存了矩形的图像)，并且想知道是否有更好的方法可以立即读取此文件(用于下一步)，或者我应该保存矩形是否不同?

我用来将矩形保存到文件的代码；

位图bmp =新位图(this.Width-100，this.Height-100，图形);
使用(Graphics g = Graphics.FromImage(bmp))
{
g.Clear(Color.White);
g.DrawRectangles(pen1，squares.ToArray());
graphics.DrawRectangles(pen1，squares.ToArray());
}
bmp.Save(Application.StartupPath +"\\ Rectangle_Image.jpg"，System.Drawing.Imaging.ImageFormat.Jpeg);


非常感谢您的帮助.

谢谢

Hi Guys

Keeping with this post, i was thinking of the best way to achieve this;
"Generate the requested amount of rectangles and write them to file (in a human readable).
Read the randomly generated input rectangles from the file generated from the above step"

I have done the first step using a bmp / jpg file (i.e. i save the image of the rectangles) and was wondering if there might be a better way to read this file back now (for the next step) or alternatively, should i be saving the rectangles differently?

Code i use to save the rectangles to file;

Bitmap bmp = new Bitmap(this.Width-100, this.Height-100 , graphics);
using (Graphics g = Graphics.FromImage(bmp))
{
g.Clear(Color.White);
g.DrawRectangles(pen1, rectangles.ToArray());
graphics.DrawRectangles(pen1, rectangles.ToArray());
}
bmp.Save(Application.StartupPath + "\\Rectangle_Image.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);


Any help is much appreciated.

Thanks
