Struct PixelMetadata 

pub struct PixelMetadata {
    pub may_have_transparency: bool,
    pub alpha_type: ImageAlphaType,
}

Metadata about the pixels of an image.

Fields

may_have_transparency: bool

Whether the pixels may be non-opaque.

If unsure, always set this to true. Setting this to false is a strong guarantee that every pixel in the image is guaranteed to be opaque. Setting this to false mistakenly can lead to wrong rendering.

alpha_type: ImageAlphaType

How the alpha channel is represented.

Implementations
