Fields

version: u8

ignore_transformations: u8

Ignore geometric transformations like cropping, rotation, mirroring. Default: false (do not ignore).

start_progress: Option<unsafe extern "C" fn(step: heif_progress_step, max_progress: c_int, progress_user_data: *mut c_void)>

Any of the progress functions may be called from background threads.

on_progress: Option<unsafe extern "C" fn(step: heif_progress_step, progress: c_int, progress_user_data: *mut c_void)>

end_progress: Option<unsafe extern "C" fn(step: heif_progress_step, progress_user_data: *mut c_void)>

progress_user_data: *mut c_void

convert_hdr_to_8bit: u8

strict_decoding: u8

When enabled, an error is returned for invalid input. Otherwise, it will try its best and add decoding warnings to the decoded heif_image. Default is non-strict.

decoder_id: *const c_char

name_id of the decoder to use for the decoding. If set to NULL (default), the highest priority decoder is chosen. The priority is defined in the plugin.

color_conversion_options: heif_color_conversion_options

cancel_decoding: Option<unsafe extern "C" fn(progress_user_data: *mut c_void) -> c_int>

color_conversion_options_ext: *mut heif_color_conversion_options_ext

When set to NULL, default options will be used

ignore_sequence_editlist: c_int

If enabled, it will decode the media timeline, ignoring the sequence tracks edit-list.

In must be used as bool type.

output_image_nclx_profile: *mut heif_color_profile_nclx

num_library_threads: c_int

0 = let libheif decide (TODO, currently ignored)

num_codec_threads: c_int

0 = use decoder default
