CloseGraphics(VintasoftImage) Метод (VintasoftImageGdiExtensions)
Этот метод генерирует событие Changed.
Вот C#/VB.NET код, который демонстрирует, как наложить два изображения.
' open the original image
Using originalImage As New Vintasoft.Imaging.VintasoftImage("c:\original-image.tif")
' open the overlay image
Using overlayImage As New Vintasoft.Imaging.VintasoftImage("c:\overlay-image.tif")
Dim g As System.Drawing.Graphics = Vintasoft.Imaging.VintasoftImageGdiExtensions.OpenGraphics(originalImage)
' draw the overlay image on the original image
Vintasoft.Imaging.VintasoftImageGdiExtensions.Draw(overlayImage, g, New System.Drawing.Rectangle(300, 400, 500, 600), New System.Drawing.Rectangle(1000, 200, 1000, 700))
End Using
' close Graphics of the overlay image
Vintasoft.Imaging.VintasoftImageGdiExtensions.CloseGraphics(originalImage)
' save original image
originalImage.Save("c:\processed-image.tif")
End Using
// open the original image
using (Vintasoft.Imaging.VintasoftImage originalImage =
new Vintasoft.Imaging.VintasoftImage(@"c:\original-image.tif"))
{
// open the overlay image
using (Vintasoft.Imaging.VintasoftImage overlayImage =
new Vintasoft.Imaging.VintasoftImage(@"c:\overlay-image.tif"))
{
System.Drawing.Graphics g = Vintasoft.Imaging.VintasoftImageGdiExtensions.OpenGraphics(originalImage);
// draw the overlay image on the original image
Vintasoft.Imaging.VintasoftImageGdiExtensions.Draw(overlayImage, g,
new System.Drawing.Rectangle(300, 400, 500, 600),
new System.Drawing.Rectangle(1000, 200, 1000, 700));
}
// close Graphics of the overlay image
Vintasoft.Imaging.VintasoftImageGdiExtensions.CloseGraphics(originalImage);
// save original image
originalImage.Save(@"c:\processed-image.tif");
}
