Example

Saving the first page of a dicom document to jpeg using different window levels.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.dcm", false);
 
    // Read the dicom properties.
    float windowWidth = gdpictureImaging.DicomGetDefaultWindowWidth(imageID);
    float windowLevel = gdpictureImaging.DicomGetMinWindowLevel(imageID);
    float maxWindowLevel = gdpictureImaging.DicomGetMaxWindowLevel(imageID);
 
    // Save different views as jpeg.
    float step = (maxWindowLevel - windowLevel) / 10;
    while (windowLevel <= maxWindowLevel)
    {
        gdpictureImaging.DicomSetWindowLevel(imageID, windowWidth, windowLevel);
        gdpictureImaging.SaveAsJPEG(imageID, "image" + windowLevel.ToString() + ".jpg", 75);
        windowLevel += step;
    }
 
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
