pub(crate) struct ImageSource<'a> {
    pub(crate) source: MediaSource<'a>,
    pub(crate) info: Option<ImageSourceInfo<'a>>,
}

info: Option<ImageSourceInfo<'a>>

Information about the image.

Implementations

impl ImageSource<'_>

fn should_thumbnail( &self, prefer_thumbnail: bool, prefer_animated: bool, thumbnail_dimensions: FrameDimensions, ) -> bool

Whether we should try to thumbnail this source for the given requested dimensions.

fn can_be_thumbnailed(&self) -> bool

Whether this source can be thumbnailed by the media repo.

Returns false in these cases:

• The image is encrypted, because it is not possible for the media repo to make a thumbnail.
• The image uses the SVG format, because media repos usually do not accept to create a thumbnail of those.

fn filesize(&self) -> Option<u32>

The filesize of this source.

fn dimensions(&self) -> Option<FrameDimensions>

The dimensions of this source.

fn is_animated(&self) -> bool

Whether this source is animated.

Returns false if the info does not say that it is animated, or if the MIME type is not one of the supported animated image formats.
