计算图像中的总像素 [英] calculate total pixels in an image

问题描述

有人可以告诉我如何使用c#

can somebody tell me how to calculate total number of pixels in an image using c#

推荐答案

位图中的像素总数是和PixelWidth 属性.有关详细信息，请参见位图和像素位 [

The total amount of pixels in a bitmap is the product of PixelHeight and PixelWidth properties. More about this is explained at Bitmaps And Pixel Bits[^].

尝试一下

仅与.Net FW 4兼容.确保您拥有

Try this

Only compatible with .Net FW 4 . Insure that you have that

Bitmap image1;

private void Button1_Click(System.Object sender, System.EventArgs e)
{

    try
    {
        // Retrieve the image.
        image1 = new Bitmap(@"C:\Documents and Settings\All Users\" 
            + @"Documents\My Music\music.bmp", true);

        int x, y;

        // Loop through the images pixels to reset color.
        for(x=0; x<image1.width;>        {
            for(y=0; y<image1.height;>            {
                Color pixelColor = image1.GetPixel(x, y);
                Color newColor = Color.FromArgb(pixelColor.R, 0, 0);
                image1.SetPixel(x, y, newColor);
            }
        }

        // Set the PictureBox to display the image.
        PictureBox1.Image = image1;

        // Display the pixel format in Label1.
        Label1.Text = "Pixel format: "+image1.PixelFormat.ToString();

    }
    catch(ArgumentException)
    {
        MessageBox.Show("There was an error." +
            "Check the path to the image file.");
    }
}
