Examples
Create a multi-page Dicom image.
[C#]
using (DicomImage image = (DicomImage)Image.Create(
new DicomOptions() { Source = new StreamSource(new MemoryStream()) },
100,
100))
{
// Draw something using vector graphics
Graphics graphics = new Graphics(image);
graphics.FillRectangle(new SolidBrush(Color.BlueViolet), image.Bounds);
graphics.FillRectangle(new SolidBrush(Color.Aqua), 10, 20, 50, 20);
graphics.FillEllipse(new SolidBrush(Color.Orange), 30, 50, 70, 30);
// Save the pixels of the drawn image. They are now on the first page of the Dicom image.
int[] pixels = image.LoadArgb32Pixels(image.Bounds);
// Add a few pages after, making them darker
for (int i = 1; i < 5; i++)
{
DicomPage page = image.AddPage();
page.SaveArgb32Pixels(page.Bounds, pixels);
page.AdjustBrightness(i * 30);
}
// Add a few pages in front of the main page, making them brighter
for (int i = 1; i < 5; i++)
{
DicomPage page = image.InsertPage(0);
page.SaveArgb32Pixels(page.Bounds, pixels);
page.AdjustBrightness(-i * 30);
}
// Save the created multi-page image to the output file
image.Save("MultiPage.dcm");
