HarmonyOS C接口获取到的图片属性没有ts接口全，C接口获取不到alphatype

ts接口获取Pixelmap的imageinfo中有alphatype，但是c接口中没有

//下面是ts返回的数据接口
interface ImageInfo {
  size: Size;
  density: number;
  stride: number;
  pixelFormat: PixelMapFormat;
  alphaType: AlphaType;
  mimeType: string;
  isHdr: boolean;
}
//下面是c接口返回的数据结构
typedef struct OhosPixelMapInfos {
  /** Image width, in pixels. */
  uint32_t width;
  /** Image height, in pixels. */
  uint32_t height;
  /** Number of bytes per row. */
  uint32_t rowSize;
  /** Pixel format. */
  int32_t pixelFormat;
} OhosPixelMapInfos;

没有alphatype
