cl.multimedia.1 Changed the Parameter Type for the HEIF Format in image.Component.OH_PackingOptions_SetMimeType()

Access Level

Public API

Reason for Change

During HEIF encoding with the camera, the encoding fails with the standard-defined image/heic parameter. The current version of Image defines the format parameter as image/heif, which does not comply with the standard definition. To improve adherence to standards, the mimeType parameter for HEIF images is changed to image/heic.

Change Impact

This change is a non-compatible change.

Before change: The mimeType parameter for HEIF images is image/heif.

After change: The mimeType parameter for HEIF images is image/heic.

Change Since

OpenHarmony 5.0.0.53

Key API/Component Changes

API in image_packer_native.h:

Image_ErrorCode OH_PackingOptions_SetMimeType(OH_PackingOptions *options, Image_MimeType *format)

Adaptation Guide

When OH_PackingOptions_SetMimeType(OH_PackingOptions *options, Image_MimeType *format) is called to set mimeType for HEIF images, the format parameter must be image/heic.

cl.multimedia.2 Changed the Return Value Type for the HEIF Format in image.Component.OH_PackingOptions_GetMimeType()

API in image_packer_native.h:

Image_ErrorCode OH_PackingOptions_GetMimeType (OH_PackingOptions * options, Image_MimeType * format)

Adaptation Guide

When OH_PackingOptions_GetMimeType(OH_PackingOptions *options, Image_MimeType *format) is called to obtain mimeType of HEIF images, format in the return value is image/heic. You need to review the sample project of the application and modify the format based on service requirements.

cl.multimedia.3 Changed the Return Value Type for the HEIF Format in image.Component.supportedFormats for Decoding

Access Level

Public API

Reason for Change

During HEIF encoding with the camera, the encoding fails with the standard-defined image/heic parameter. The current version of Image defines the format parameter as image/heif, which does not comply with the standard definition. To improve adherence to standards, the mimeType parameter for HEIF images is changed to image/heic.

Change Impact

This change is a non-compatible change.

Before change: The return value of the decoding type supported by the device for HEIF images is image/heif.

After change: The return value of the decoding type supported by the device for HEIF images is image/heic.

Change Since

OpenHarmony 5.0.0.53

Key API/Component Changes

Property in /interface/sdk-js/api/@ohos.multimedia.image.d.ts:

image.Component.readonly supportedFormats: Array<string>

Adaptation Guide

When this property is used to obtain the decoding type of a device, the calling behavior remains unchanged. If the device supports HEIF, the return value is changed from image/heif to image/heic.
