c – 复制到d3dtexture的FreeType2字符显示为双字母

我现在正在获得双字母,尽管从通过加载单个字符创建的缓冲区复制如下：

[复制角色’a’的尝试]

以下是我目前的代码：

void TexFont::freeTypeSave()
{
    static FT_Library  library;   /* handle to library     */
    static FT_Face     face;      /* handle to face object */

    if (FT_Init_FreeType(&library)) {
        NHelper::OutputDebugStringN("error");
    }

    if (FT_New_Face(library,TEXT("Fontsarial.ttf"),&face)) {
        NHelper::OutputDebugStringN("font load failedn");
    }
    else {
        //NHelper::OutputDebugStringN("font faces: %d n",face->num_faces);
    }

    static int error;
    static UINT width,height;
    static int mTtfSize = 64;
    static int mTtfResolution = 96;

    static IDirect3DTexture9* mTexture;
    static unsigned int mPixelBytes = 2;
    static unsigned int mDataSize = width * height * mPixelBytes;

    // size settings (convert font size to *64)
    FT_F26Dot6 ftSize = (FT_F26Dot6)(mTtfSize * (1 << 6));
    error=FT_Set_Char_Size(face,ftSize,mTtfResolution,mTtfResolution);

    // load glyph + render
    error = FT_Load_Char( face,L'a',FT_LOAD_RENDER );
    if (error) 
        NHelper::OutputDebugStringN("could not load char");

    // start copy procedure
    width = face->glyph->bitmap.width;
    height = face->glyph->bitmap.rows;

    D3DXCreateTexture(
        g_engine->getDevice(),width,height,1,D3DFMT_A8L8,D3DPOOL_MANAGED,&mTexture);

    D3DLOCKED_RECT lockedRect;
    mTexture->LockRect(0,&lockedRect,0);   

    unsigned char* pSrcPixels = face->glyph->bitmap.buffer;
    unsigned char* pDestPixels = (unsigned char*)lockedRect.pBits;

    for(UINT i = 0; i < height; ++i)
    {
        //copy a row
        memcpy(pDestPixels,pSrcPixels,width * 2); //2 bytes per pixel (1byte alpha,1byte greyscale)

        //advance row pointers
        pSrcPixels += face->glyph->bitmap.pitch;
        pDestPixels += lockedRect.Pitch;
    }
    NHelper::OutputDebugStringN("char width: %d,height: %d n",height);

    mTexture->UnlockRect(0);

    D3DXSaveTextureToFileA("test.png",D3DXIFF_PNG,mTexture,0);

    // release face
    FT_Done_Face(face);

    // library shutdown
    FT_Done_FreeType(library);
}

关于发生了什么以及如何解决这个问题的任何想法？

注意：更改字体大小只会创建更大的图像.我仍然得到相同的结果.

–update–

尝试Drop的建议,我尝试更改我的memcpy(pDestPixels,width * 2);

memcpy(pDestPixels,width * 1);它返回以下内容：

一个字形打包在图像的左侧,但图像保持相同的大小.
(字形只占用图像空间的一半)
