Struct DecodeOptions 

pub struct DecodeOptions {
    pub max_size: Option<[u32; 2]>,
    pub mipmaps: bool,
    pub limits: DecodeLimits,
}

DecodeOptions says how large a decode may be and what the caller wants out of it.

Fields

max_size: Option<[u32; 2]>

max_size asks for frames no larger than this box, keeping the aspect ratio.

Decoders never upscale: the GPU does that for free at draw time, while decoding larger only costs memory. A native decoder scales while it decodes, which is the point of asking here rather than resizing afterwards. None decodes at the intrinsic size.

mipmaps: bool

mipmaps asks for a full mip chain, for images that will be drawn smaller than decoded.

limits: DecodeLimits

limits bound the input and every frame, for untrusted bytes.

Implementations

impl DecodeOptions

pub fn fit(&self, source: [u32; 2]) -> [u32; 2]

fit is the output size for a source of source pixels under max_size.
