我正在尝试创建一个离屏位图来在其上绘制,然后使用Direct2D1.RenderTarget.DrawBitmap
进行绘制。因此,我创建了 Texture2D
并从中获取位图。但我收到错误
[D2DERR_UNSUPPORTED_PIXEL_FORMAT/UnsupportedPixelFormat]
在最后一串代码中。请帮助我理解,我在这里做错了什么?
m_texture = new Texture2D(
context.Device,
new Texture2DDescription() {
ArraySize = 1,
BindFlags = BindFlags.RenderTarget | BindFlags.ShaderResource,
CpuAccessFlags = CpuAccessFlags.None,
Format = Format.B8G8R8A8_UNorm,
Height = bitmapSize.Height,
Width = bitmapSize.Width,
MipLevels = 1,
OptionFlags = ResourceOptionFlags.None,
SampleDescription = new SampleDescription() {
Count = 1,
Quality = 0
},
Usage = ResourceUsage.Default
}
);
m_surface = m_texture.QueryInterface<Surface>();
using (SharpDX.Direct2D1.Factory factory = new SharpDX.Direct2D1.Factory()) {
m_renderTarget = new RenderTarget(
factory,
m_surface,
new RenderTargetProperties() {
DpiX = 0.0f, // default dpi
DpiY = 0.0f, // default dpi
MinLevel = SharpDX.Direct2D1.FeatureLevel.Level_DEFAULT,
Type = RenderTargetType.Hardware,
Usage = RenderTargetUsage.None,
PixelFormat = new SharpDX.Direct2D1.PixelFormat(
Format.Unknown,
AlphaMode.Premultiplied
)
}
);
}
m_bitmap = new SharpDX.Direct2D1.Bitmap(m_renderTarget, m_surface);
最佳答案
public static SharpDX.Direct2D1.Bitmap GetBitmapFromSRV(SharpDX.Direct3D11.ShaderResourceView srv, RenderTarget renderTarger)
{
using (var texture = srv.ResourceAs<Texture2D>())
using (var surface = texture.QueryInterface<Surface>())
{
var bitmap = new SharpDX.Direct2D1.Bitmap(renderTarger, surface, new SharpDX.Direct2D1.BitmapProperties(new SharpDX.Direct2D1.PixelFormat(
Format.R8G8B8A8_UNorm,
SharpDX.Direct2D1.AlphaMode.Premultiplied)));
return bitmap;
}
}
