Enum PixelFormat 

#[non_exhaustive]
pub enum PixelFormat {
    Bgra8,
    Rgba8,
    Bgr8,
    Gray8,
}

Pixel layout of a rendered bitmap.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Bgra8

4 bytes/pixel: blue, green, red, alpha — straight (non-premultiplied) alpha. PDFium’s native format.

Rgba8

4 bytes/pixel: red, green, blue, alpha — straight alpha. Rendered by PDFium with its reverse-byte-order flag; convenient for image/PNG interop.

Bgr8

3 bytes/pixel: blue, green, red. No alpha.

Gray8

1 byte/pixel grayscale.
