HarmonyOS gif对应的ArkUI_DrawableDescriptor怎么创建

if (nodeAPI->createNode != nullptr && nodeAPI->addChild != nullptr) {

  ArkUI_NodeHandle imageNode = nodeAPI->createNode(ARKUI_NODE_IMAGE);
  uint8_t data[96];
  for (auto i = 0; i < 92; i++) {
    data[i] = uint8_t(0);
    data[i + 1] = uint8_t(0);
    data[i + 2] = uint8_t(0);
    data[i + 3] = uint8_t(255);
    i = i + 4;
  }
  OH_Pixelmap_InitializationOptions *options = nullptr;
  OH_PixelmapInitializationOptions_Create(&options);
  OH_PixelmapInitializationOptions_SetWidth(options, 4);
  OH_PixelmapInitializationOptions_SetHeight(options, 6);
  OH_PixelmapInitializationOptions_SetPixelFormat(options, 4);
  OH_PixelmapInitializationOptions_SetAlphaType(options, 0);

  OH_PixelmapNative *g_PixelMap = nullptr;
  OH_PixelmapNative_CreatePixelmap(data, 96, options, &g_PixelMap);
  ArkUI_DrawableDescriptor *drawable = nullptr;
  drawable = OH_ArkUI_DrawableDescriptor_CreateFromPixelMap(g_PixelMap);
  ArkUI_AttributeItem img_src_item = {.object = drawable};
  nodeAPI->setAttribute(imageNode, NODE_IMAGE_SRC, &img_src_item);
  ArkUI_NumberValue value[1] = {{.f32 = 300}};
ArkUI_AttributeItem item = {value, 1};
nodeAPI->setAttribute(imageNode, NODE_HEIGHT, &item);
nodeAPI->setAttribute(imageNode, NODE_WIDTH, &item);
OH_NativeXComponent_AttachNativeRootNode(component, imageNode);
