SharpDX、DirectWrite和Windows窗体
提问于 2012-03-26 04:17:54
可以在WinForm应用程序中使用DirectWrite向PictureBox呈现文本吗？
我正在使用SharpDX，并且已经浏览了DirectWrite示例，试图尽可能构建最简单的工作用例。
我创建了一个表单，并且只向其中添加了一个pictureBox。然后是下面的代码。将显示表单，但PictureBox中看不到任何内容。
任何指导都将不胜感激。
谢谢!

嗨，我有点像你的问题例子，但我终于设法解决了，因为我想独立地开始编写游戏，所有的绘制方法都必须在RenderTarget类的beginDraw和endDraw方法中。您还需要实现RenderLoop类，这将为您提供回调循环委托。很抱歉我的代码太粗糙了。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using SharpDX.Direct3D;
using SharpDX.Direct2D1;
using System.Text;
using System.Windows.Forms;
using System.Drawing;
using SharpDX.DXGI;
using SharpDX;
using SharpDX.Windows;
using System.Globalization;
using SharpDX.DirectWrite;
namespace dx11
{
public partial class Form1 : Form
{
private SharpDX.Direct3D10.Device _mDevice = null;
WindowRenderTarget wndRender = null;
SharpDX.Direct2D1.Factory fact = new SharpDX.Direct2D1.Factory(SharpDX.Direct2D1.FactoryType.SingleThreaded);
SolidColorBrush scenebrush;
RenderTargetProperties rndTargProperties;
HwndRenderTargetProperties hwndProperties;
SharpDX.Windows.RenderForm form = new RenderForm();
RenderLoop.RenderCallback callback;
public Form1()
{
InitializeComponent();
SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint, true);
form.Width = 600;
form.Height = 600;
test();
callback = new RenderLoop.RenderCallback(Render);
RenderLoop.Run(form, callback);
}
private void test()
{
rndTargProperties = new RenderTargetProperties(new PixelFormat(Format.B8G8R8A8_UNorm, AlphaMode.Premultiplied));
hwndProperties = new HwndRenderTargetProperties();
hwndProperties.Hwnd = form.Handle;
hwndProperties.PixelSize = new SharpDX.DrawingSize(form.ClientSize.Width, form.ClientSize.Height);
hwndProperties.PresentOptions = PresentOptions.None;
wndRender = new WindowRenderTarget(fact, rndTargProperties, hwndProperties);
scenebrush = new SolidColorBrush(wndRender, Colors.Red);
// scenebrush.Color = Colors.Cornsilk;
form.Show();
}
public void Render()
{
wndRender.BeginDraw();
wndRender.Clear(Colors.DarkBlue);
wndRender.DrawRectangle(new SharpDX.RectangleF(10, 10, 50, 50), scenebrush, 2.00F);
wndRender.Flush();
wndRender.EndDraw();
}
}
}这将创建一个在左上角带有红色正方形的蓝色窗体。

实际上，您并不想使用HwndRenderTarget呈现“到PictureBox中”。实际上，您希望渲染到PictureBox负责渲染的位图中。您可以通过创建一个“共享位图”(我对SharpDX不是特别熟悉，但底层方法是ID2D1RenderTarget::CreateSharedBitmap())，渲染到其中，然后在调用EndDraw()之后使PictureBox无效。
