如何对齐SpriteBatch.DrawString绘制的文本？

D3D11_TEXTURE_ADDRESS_MODE addressMode = D3D11_TEXTURE_ADDRESS_CLAMP;
float textSize = 24;
float textColor[4] = {1.0f, 1.0f, 1.0f, 1.0f};
float textX = 0.0f;
float textY = 0.0f;

D3D11_SPRITE_BATCH_PARAMETERS params = {};
params.TextureAddressMode = addressMode;
params.TextureFilterType = D3D11_FILTER_ANISOTROPIC;
params.TextureMaxWidth = 1920.0f;
params.TextureMaxHeight = 1080.0f;

DrawString(device, text, textSize, textColor, textX, textY, params);
