Implementations§

Source§

impl ImageSource

Source

pub fn frame_count(&self) -> u32

Return the number of frame in the image. For most format (ex: PNG), this will be 1. It might be more than 1 in animated image formats (such as GIFs).

Source

pub fn frame(&self, index: u32) -> Result<ImageData, NwgError>

Return the image data of the requested frame in a ImageData object.

Source

pub fn container_format(&self) -> ContainerFormat
