Struct Visual 

pub struct Visual { /* private fields */ }

A Visual contains information about a particular visual.

Implementations

impl Visual

pub fn blue_pixel_details(&self) -> (u32, i32, i32)

Obtains values that are needed to calculate blue pixel values in TrueColor and DirectColor. The “mask” is the significant bits within the pixel. The “shift” is the number of bits left we must shift a primary for it to be in position (according to the “mask”). Finally, “precision” refers to how much precision the pixel value contains for a particular primary.

Returns

mask

A pointer to a guint32 to be filled in, or None

shift

A pointer to a gint to be filled in, or None

precision

A pointer to a gint to be filled in, or None

pub fn depth(&self) -> i32

Returns the bit depth of this visual.

Returns

The bit depth of this visual.

pub fn green_pixel_details(&self) -> (u32, i32, i32)

Obtains values that are needed to calculate green pixel values in TrueColor and DirectColor. The “mask” is the significant bits within the pixel. The “shift” is the number of bits left we must shift a primary for it to be in position (according to the “mask”). Finally, “precision” refers to how much precision the pixel value contains for a particular primary.

Returns

mask

A pointer to a guint32 to be filled in, or None

shift

A pointer to a gint to be filled in, or None

precision

A pointer to a gint to be filled in, or None

pub fn red_pixel_details(&self) -> (u32, i32, i32)

Obtains values that are needed to calculate red pixel values in TrueColor and DirectColor. The “mask” is the significant bits within the pixel. The “shift” is the number of bits left we must shift a primary for it to be in position (according to the “mask”). Finally, “precision” refers to how much precision the pixel value contains for a particular primary.

Returns

mask

A pointer to a guint32 to be filled in, or None

shift

A pointer to a gint to be filled in, or None

precision

A pointer to a gint to be filled in, or None

pub fn screen(&self) -> Screen

Gets the screen to which this visual belongs

Returns

the screen to which this visual belongs.

pub fn visual_type(&self) -> VisualType

Returns the type of visual this is (PseudoColor, TrueColor, etc).

Returns

A VisualType stating the type of self.

impl Visual
