Struct ImageSource

Source
pub struct ImageSource<'a> {
    pub source: MediaSource<'a>,
    pub info: Option<ImageSourceInfo<'a>>,
}
Expand description

The source of an image.

Fields§

§source: MediaSource<'a>

The source of the image.

§info: Option<ImageSourceInfo<'a>>

Information about the image.

Implementations§

Source§

impl ImageSource<'_>

Source

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

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

Source

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.
Source

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

The filesize of this source.

Source

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

The dimensions of this source.

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.
