Struct pdfium_render::color::PdfColor

source · [−]

pub struct PdfColor { /* private fields */ }

Expand description

A 32-bit RGB color value with an optional alpha channel.

Certain basic primary colors are available as const values on this struct.

Note that when used as a form field highlight color, a solid color with no opacity will overprint any user data in the field. Use the PdfColor::with_alpha() function to apply an alpha channel value to an existing PdfColor.

Implementations

source

pub const fn new(red: u8, green: u8, blue: u8, alpha: u8) -> Self

Constructs a new PdfColor object from the given arguments.

source

pub const fn with_alpha(&self, alpha: u8) -> Self

Constructs a new PdfColor by copying the red, green, and blue color components of this color and applying the given alpha value.

source

pub fn red(&self) -> u8

Returns the red component of this color.

source

pub fn green(&self) -> u8

Returns the green component of this color.

source

pub fn blue(&self) -> u8

Returns the blue component of this color.

source

pub fn alpha(&self) -> u8

Returns the alpha (opacity) component of this color, with 0 = completely transparent and 255 = completely opaque (solid).
