将图像转换为像素格式 - c#

我对下面的代码有问题。我能够将图像转换为我想要的像素格式。但问题是，当我将位图用于图片框时，它只是黑色。

sourceImage = new Bitmap(sourceImage.Width, sourceImage.Height,
System.Drawing.Imaging.PixelFormat.Format24bppRgb);

pictureBoxCurrency.Image = sourceImage;

I have a problem with the code below. I was able to convert the image into the pixel format I want. But the problem is that when I use the bitmap for my picturebox, its just black.

sourceImage = new Bitmap(sourceImage.Width, sourceImage.Height,
System.Drawing.Imaging.PixelFormat.Format24bppRgb);

pictureBoxCurrency.Image = sourceImage;

您已经创建了新的位图，但您需要将图像从原始图像绘制（传输）到新图像。

Bitmap newBitmap = new Bitmap(sourceImage.Size.Width, sourceImage.Size.Height, System.Drawing.Imaging.PixelFormat.Format24bppRgb);
Graphics g = Graphics.FromImage(newBitmap);
g.DrawImage(sourceImage, new Point(0, 0));
g.Dispose();

pictureBoxCurrency.Image = sourceImage;

You have created the new bitmap, but you need to paint the image (transfer) from the original one to the new one.

Bitmap newBitmap = new Bitmap(sourceImage.Size.Width, sourceImage.Size.Height, System.Drawing.Imaging.PixelFormat.Format24bppRgb);
Graphics g = Graphics.FromImage(newBitmap);
g.DrawImage(sourceImage, new Point(0, 0));
g.Dispose();

pictureBoxCurrency.Image = sourceImage;
