DataGridView中绘制晶片图 [英] Datagridview to draw wafer map

问题描述

目前我使用的是C＃的datagridview绘制晶圆图，其中包含> 500行和> 700列。

Currently I'm using C# datagridview to draw a wafer map which contains >500 rows and >700 columns.

然而，有几个问题：

1. 降低性能。因为我需要调整列宽，我不得不遍历和单独分配。

1. Slow performance. As i need to adjust the column width, I have to loop through and assign individually.

for (int i = 0; i < this.dgvCompleteMapGrid.Columns.Count; i++)
{
  this.dgvCompleteMapGrid.Columns[i].Width = 8;
}

我只需要绘制单元格边框的细胞值作为晶圆图有一个近圆形的形状。我使用cellpainting事件：

I only need to draw the cell border for cells with value as a wafer map has an almost round shape. I'm using cellpainting event:

 if (e.Value != null) {
        if (e.Value.ToString() == "")
        {
         e.AdvancedBorderStyle.All = DataGridViewAdvancedCellBorderStyle.None;                    
        }
        else
        {                    
            if (e.Value.ToString() == "1")
            {
                e.CellStyle.BackColor = Color.Lime;
            }
            else
            {
                e.CellStyle.BackColor = Color.Red;
            }

            //check if the top border set None for neighbor empty value cell
            if (e.AdvancedBorderStyle.Top.ToString() == "None")
            {

       e.AdvancedBorderStyle.Top = DataGridViewAdvancedCellBorderStyle.Single;
            }   
            //repeat the same for left right and bottom
        }
    }

不过，现在看来似乎将绘制多个边界复制的大多数细胞。

However, it seems like it will draw multiple border duplicate for most of the cells.

时的datagridview的建议？我试着画一个矩形面板上的表现更差。

Is Datagridview recommended? I tried to draw rectangle on a panel and the performance is even worse.

推荐答案

下面是我的图片框，允许像素化调整大小（与插值）。例如。类似于在Microsoft画图图片放大

Here's my Picturebox that allows for pixellated resizing (versus interpolated). E.g. similar to zooming in on a Microsoft Paint picture.

using System.Windows.Forms;

namespace WireWorld
{
    public class ZoomablePicturebox : PictureBox
    {
        public ZoomablePicturebox()
        {
        }

        protected override void OnPaint(PaintEventArgs pe)
        {
            pe.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.None;
            pe.Graphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.NearestNeighbor;
            pe.Graphics.CompositingMode = System.Drawing.Drawing2D.CompositingMode.SourceCopy;
            pe.Graphics.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighSpeed;
            base.OnPaint(pe);
        }
    }
}

要生成位图，我用的是这样的：

To generate the bitmap, I use something like this:

// Pick width and height for your case
Bitmap MyBitmap = new Bitmap(width, height);
using (var g = Graphics.FromImage(retVal))
    g.Clear(BackColor); // Pick a background fill color
// Draw your points, whatever your loop needs to be and your point definition is
foreach (MyPointDef point in _Points)
{
    MyBitmap.SetPixel(point.X, point.Y, point.Color);
}

然后，我把一个图片框在一个面板上我的形式。面板则提供了滚动。我可以设置图片和缩放如下：

Then I put a picture box in a panel on my form. The panel then provides the scrolling. I can set the picture and zoom as follows:

canvasPB.SizeMode = PictureBoxSizeMode.Zoom; // Ensures picture is resized as we resize picturebox
canvasPB.Image = MyBitmap;
canvasPB.Height = canvasPB.Image.Height * Zoom; // Zoom is 1, 2, 3, etc, for 1X, 2X, ...
canvasPB.Width = canvasPB.Image.Width * Zoom;

canvasPB作为图片框的名字我的形式我想为我的画布使用。

canvasPB being the name of the Picturebox on my form I'm trying to use as my canvas.
