EffectEditor.Controls.GraphicsDeviceService.ResetDevice C# (CSharp) Метод

ResetDevice() публичный Метод

Resets the graphics device to whichever is bigger out of the specified resolution or its current size. This behavior means the device will demand-grow to the largest of all its GraphicsDeviceControl clients.

Результат void
        public void ResetDevice(int width, int height)
        {
            if (DeviceResetting != null)
                DeviceResetting(this, EventArgs.Empty);

            parameters.BackBufferWidth = Math.Max(parameters.BackBufferWidth, width);
            parameters.BackBufferHeight = Math.Max(parameters.BackBufferHeight, height);

            graphicsDevice.Reset(parameters);

            if (DeviceReset != null)
                DeviceReset(this, EventArgs.Empty);

Usage Example

        /// <summary>
        /// Helper used by BeginDraw. This checks the graphics device status,
        /// making sure it is big enough for drawing the current control, and
        /// that the device is not lost. Returns an error string if the device
        /// could not be reset.
        /// </summary>
        string HandleDeviceReset()
        {
            bool deviceNeedsReset = false;

            switch (GraphicsDevice.GraphicsDeviceStatus)
            {
            case GraphicsDeviceStatus.Lost:
                // If the graphics device is lost, we cannot use it at all.
                return("Graphics device lost");

            case GraphicsDeviceStatus.NotReset:
                // If device is in the not-reset state, we should try to reset it.
                deviceNeedsReset = true;
                break;

            default:
                // If the device state is ok, check whether it is big enough.
                PresentationParameters pp = GraphicsDevice.PresentationParameters;

                deviceNeedsReset = (ClientSize.Width > pp.BackBufferWidth) ||
                                   (ClientSize.Height > pp.BackBufferHeight);
                break;
            }

            // Do we need to reset the device?
            if (deviceNeedsReset)
            {
                try
                {
                    graphicsDeviceService.ResetDevice(ClientSize.Width,
                                                      ClientSize.Height);
                }
                catch (Exception e)
                {
                    return("Graphics device reset failed\n\n" + e);
                }
            }

            return(null);
        }
