我希望使用simpleitk读取dicom图片,将其转换为位图,然后在pictureBox中显示结果。但是当我尝试这样做时,会抛出ArgumentException异常。我该如何解决?
以下是我的代码:
以下是我的代码:
OpenFileDialog dialog = new OpenFileDialog();
dialog.Title = "Open";
dialog.Filter = "DICOM Files (*.dcm;*.dic)|*.dcm;*.dic|All Files (*.*)|*.*";
dialog.ShowDialog();
if (dialog.FileName != "")
{
using (sitk.ImageFileReader reader = new sitk.ImageFileReader())
{
reader.SetFileName(dialog.FileName);
reader.SetOutputPixelType(sitk.PixelIDValueEnum.sitkFloat32);
sitk.Image image = reader.Execute();
var castedImage = sitk.SimpleITK.Cast(image,
sitk.PixelIDValueEnum.sitkFloat32);
var size = castedImage.GetSize();
int length = size.Aggregate(1, (current, i) => current * (int)i);
IntPtr buffer = castedImage.GetBufferAsFloat();
// Declare an array to hold the bytes of the bitmap.
byte[] rgbValues = new byte[length];
// Copy the RGB values into the array.
Marshal.Copy(buffer, rgbValues, 0, length);
Stream stream = new MemoryStream(rgbValues);
Bitmap newBitmap = new Bitmap(stream);
//I have tried in this way, but it generated ArgumentException too
//Bitmap newBitmap = new Bitmap((int)image.GetWidth(), (int)image.GetHeight(), (int)image.GetDepth(), PixelFormat.Format8bppIndexed, buffer);
Obraz.pic.Image = newBitmap;
}
}
if (dialog.ShowDialog() == DialogResult.OK){ }
另外,错误出现在哪一行?你使用了调试器吗?你是否搜索过关于任何位图转换函数的信息等? - MethodManfloat[]
而不是byte[]
