使用方框打印位图

标签: c# colors bitmap

我想构建一个用x行和y列打印的位图,使每个框的大小为10 x 10像素。

现在,当我通过时:

private void printBitmap(rows, columns, numOfWhites, numOfblack, numOf(green or brown)) {
// i want to be able to build a bitmap with rows and columns with White to top right, 
// black to bottom right, if green or brown fill the box with green or brown 
// except the area with white or black 
// how do i do this in C# ?
}

我们不是来做你的工作,所以这里有一个启动者的提示:

然后画线:

哇超级难啊! :d

当然!

private void printBitmap(rows, columns, numOfWhites, numOfblack /*, numOf... */) {
    Bitmap bmp = new Bitmap(rows * 10, columns * 10);
    Graphics g = Graphics.FromImage(bmp);
    SolidBrush bWhite = new SolidBrush(Color.White);
    SolidBrush bBlack = new SolidBrush(Color.Black);
    // ...SolidBrush bColor = new SolidBrush(Color.AnyColor);
    // ...
    int countNumOfWhites = 0;
    int countNumOfBlacks = 0;
    // int countNumOf... = 0;
    // ...
    for(int c = 0; c < columns; c++)
    {
        for(int r = 0; r < rows; r++)
        {
            if(countNumOfWhites < numOfWhites)
            {
                g.FillRectangle(bWhite, new Rectangle(r * 10, c * 10, (r + 1) * 10, (c + 1) * 10);
                countNumOfWhites++; 
            }
            else if(countNumOfBlacks < numOfBlacks)
            {
                g.FillRectangle(bBlack, new Rectangle(r * 10, c * 10, (r + 1) * 10, (c + 1) * 10);
                countNumOfBlacks++;
            }
            //else if(countNumOf... < numOf...)
            //{
            //    g.FillRectangle(b..., new Rectangle(r * 10, c * 10, (r + 1) * 10, (c + 1) * 10);
            //    countNumOf...++;
            //}
        }
    }
    bmp.Save("printedbitmap.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
}

这只是一个片段,所以我没有测试我的代码。

我希望我可以提供帮助。
