Struct webp::BitstreamFeatures [−][src]
pub struct BitstreamFeatures(_);
A wrapper around libwebp-sys::WebPBitstreamFeatures which allows to get information about the image.
Implementations
impl BitstreamFeatures[src]
pub fn new(data: &[u8]) -> Option<Self>[src]
pub fn width(&self) -> u32[src]
Returns the width of the image as described by the bitstream in pixels.
pub fn height(&self) -> u32[src]
Returns the height of the image as described by the bitstream in pixels.
pub fn has_alpha(&self) -> bool[src]
Returns true if the image as described by the bitstream has an alpha channel.
pub fn has_animation(&self) -> bool[src]
Returns true if the image as described by the bitstream is animated.
pub fn format(&self) -> Option<BitstreamFormat>[src]
Returns the format of the image as described by image bitstream.
