# 图形子系统ChangeLog # cl.image.1 @ohos.multimedia.image中getDelayTime更名为getDelayTimeList **变更影响** 对于已发布的JS接口，可能影响应用的兼容性。 **适配指导** 针对已使用该接口开发的应用工程，需要对接口进行适配，将接口修改为getDelayTimeList。 **示例：** ```js import image from '@ohos.multimedia.image'; let testJpg = new Uint8Array([255, 216, 255, 224, 0, 16, 74, 70, 73, 70, 0, 1, 1, 1, 0, 96, 0, 96, 0, 0, 255, 219, 0, 67, 0, 2, 1, 1, 2, 1, 1, 2, 2, 2, 2, 2, 2, 2,

移动除API8以外的接口到image_pixel_map_mdk.h，并去除命名空间 **变更影响** 对于已发布的Ndk接口，可能影响应用的兼容性。 废弃接口替换方案如下： OHOS::Media::OH_GetImageInfo 替换为 OH_PixelMap_GetImageInfo OHOS::Media::OH_AccessPixels 替换为 OH_PixelMap_AccessPixels OHOS::Media::OH_UnAccessPixels 替换为 OH_PixelMap_UnAccessPixels 涉及变更的接口范围如下： OH_PixelMap_CreatePixelMap (napi_env env, OhosPixelMapCreateOps info, void *buf, size_t len, napi_value *res) OH_PixelMap_CreateAlphaPixelMap (napi_env env, napi_value source, napi_value *alpha) OH_PixelMap_InitNativePixelMap (napi_env env, napi_value source) OH_PixelMap_GetBytesNumberPerRow (const NativePixelMap *native, int32_t *num) OH_PixelMap_GetIsEditable (const NativePixelMap *native, int32_t *editable) OH_PixelMap_IsSupportAlpha (const NativePixelMap *native, int32_t *alpha) OH_PixelMap_SetAlphaAble (const NativePixelMap *native, int32_t alpha) OH_PixelMap_GetDensity (const NativePixelMap *native, int32_t *density) OH_PixelMap_SetDensity (const NativePixelMap *native, int32_t density) OH_PixelMap_SetOpacity (const NativePixelMap *native, float opacity) OH_PixelMap_Scale (const NativePixelMap *native, float x, float y) OH_PixelMap_Translate (const NativePixelMap *native, float x, float y) OH_PixelMap_Rotate (const NativePixelMap *native, float angle) OH_PixelMap_Flip (const NativePixelMap *native, int32_t x, int32_t y) OH_PixelMap_Crop (const NativePixelMap *native, int32_t x, int32_t y, int32_t width, int32_t height) OH_PixelMap_GetImageInfo (const NativePixelMap *native, OhosPixelMapInfos *info) OH_PixelMap_AccessPixels (const NativePixelMap *native, void **addr) OH_PixelMap_UnAccessPixels (const NativePixelMap *native) **适配指导** 1. 添加头文件image_pixel_map_mdk.h。 2. 去除image_pixel_map_mdk.h中接口调用中的命名空间。 **示例：** ``` #include "napi/native_api.h" #include "image_pixel_map_mdk.h" #include "image_pixel_map_napi.h" ... static NativePixelMap* getNativePixelMap(napi_env env, napi_callback_info info) { napi_value thisVar = nullptr; napi_value argValue[NUM_1] = {0}; size_t argCount = NUM_1; if (napi_get_cb_info(env, info, &argCount, argValue, &thisVar, nullptr) != napi_ok || argCount < NUM_1 || argValue[NUM_0] == nullptr) { return nullptr; } return OH_PixelMap_InitNativePixelMap(env, argValue[NUM_0]); } ... ```
