Implementations

impl<'a> ImageHandle<'a>

pub fn decode(
    &self,
    color_space: ColorSpace,
    ignore_transformations: bool
) -> Result<Image>

pub fn width(&self) -> u32

pub fn height(&self) -> u32

pub fn has_alpha_channel(&self) -> bool

pub fn is_primary(&self) -> bool

pub fn luma_bits_per_pixel(&self) -> u8

pub fn chroma_bits_per_pixel(&self) -> u8

pub fn ispe_width(&self) -> i32

Get the image width from the ‘ispe’ box. This is the original image size without any transformations applied to it. Do not use this unless you know exactly what you are doing.

pub fn ispe_height(&self) -> i32

Get the image height from the ‘ispe’ box. This is the original image size without any transformations applied to it. Do not use this unless you know exactly what you are doing.

pub fn has_depth_image(&self) -> bool

pub fn number_of_depth_images(&self) -> i32

pub fn list_of_depth_image_ids(&self, count: usize) -> Vec<ItemId>

👎 Deprecated since 0.14.0:

Please use the depth_image_ids method instead

pub fn depth_image_ids(&self, item_ids: &mut [ItemId]) -> usize

pub fn depth_image_handle(
    &self,
    depth_image_id: ItemId
) -> Result<ImageHandle<'_>>

pub fn number_of_thumbnails(&self) -> usize

pub fn list_of_thumbnail_ids(&self, count: usize) -> Vec<ItemId>

👎 Deprecated since 0.14.0:

Please use the thumbnail_ids method instead

pub fn thumbnail_ids(&self, item_ids: &mut [ItemId]) -> usize

pub fn thumbnail(&self, thumbnail_id: ItemId) -> Result<ImageHandle<'_>>

pub fn list_of_metadata_block_ids(
    &self,
    type_filter: &str,
    count: usize
) -> Vec<ItemId>

👎 Deprecated since 0.14.0:

Please use the metadata_block_ids method instead

pub fn metadata_block_ids(
    &self,
    type_filter: &str,
    item_ids: &mut [ItemId]
