c++ - 在 C++ DirectX Tool Kit 中渲染纹理问题

Question

我正在尝试使用 DirectX 工具包中的函数 CreateWICtextureFromFile 从 .jpg 文件加载纹理。我的图像作为纹理加载，但输出有抖动和缺失信息。这是我的代码快照

    D3D11_SAMPLER_DESC samplerdesc;
    samplerdesc.Filter = D3D11_FILTER_MIN_MAG_MIP_LINEAR;
    samplerdesc.AddressU = D3D11_TEXTURE_ADDRESS_WRAP;
    samplerdesc.AddressV = D3D11_TEXTURE_ADDRESS_WRAP;
    samplerdesc.AddressW = D3D11_TEXTURE_ADDRESS_WRAP;
    samplerdesc.MipLODBias = 0.0f;
    samplerdesc.MaxAnisotropy = 1;
    samplerdesc.ComparisonFunc = D3D11_COMPARISON_ALWAYS;
    samplerdesc.BorderColor[0] = 0.5;
    samplerdesc.BorderColor[1] = 0.5;
    samplerdesc.BorderColor[2] = 0.5;
    samplerdesc.BorderColor[3] = 0.5;
    samplerdesc.MinLOD = 0;
    samplerdesc.MaxLOD = D3D11_FLOAT32_MAX;

    Device->CreateSamplerState(&samplerdesc, &samplestate);

====================================

DirectX::CreateWICTextureFromFile(Device, L"xyz.jpg", nullptr, &resourceview);

====================================

像素着色器文件

    texcolor = shader.Sample(Sample, tex);
    texcolor.w=0;
    return  textureColor;

================================

    texDesc.Width = width;
    texDesc.Height = height;
    texDesc.MipLevels = 1;
    texDesc.ArraySize = 1;
    texDesc.Format = DXGI_FORMAT_B8G8R8A8_UNORM;
    texDesc.SampleDesc.Count = 1;
    texDesc.Usage = D3D11_USAGE_DEFAULT;
    texDesc.BindFlags = D3D11_BIND_RENDER_TARGET | D3D11_BIND_SHADER_RESOURCE;
    texDesc.MiscFlags = D3D11_RESOURCE_MISC_SHARED;
