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