Enum TileFormat 

pub enum TileFormat {
    Png,
    Webp,
    Jpeg,
}

Output encoding for a rendered tile.

All three variants exist regardless of cargo features so public APIs can carry a requested format explicitly. Requests for formats whose feature is disabled fail via TileFormat::ensure_available or encode.

Variants

Png

Lossless RGBA PNG, available in every build.

Webp

Lossless RGBA WebP; encoding requires the webp feature.

Jpeg

Lossy JPEG with transparency flattened over black; requires jpeg.

Implementations

impl TileFormat

pub fn content_type(&self) -> &'static str

pub fn extension(&self) -> &'static str

Canonical file extension (without the dot).

pub fn feature_name(&self) -> Option<&'static str>

Cargo feature required for this format, if any.

pub fn is_available(&self) -> bool

Whether this format can be encoded by the current build.

pub fn ensure_available(&self) -> AgResult<()>

Return an error before doing tile work when the requested encoder is not present in this build.
