Detailed Description

Information extracted from a HEIF image and its container.

Info reports facts available in the input independently of whether GD can decode or write every feature. Width, height, alpha, and bit depth describe the primary image. top_level_image_count and is_animation describe the container when available; they do not add a frame/page decoding API. metadata is caller-owned and is populated with canonical exif, xmp, and iptc profiles. HEIF's ICC color profile is intentionally not exposed as metadata.

The documentation for this struct was generated from the following file:
