Struct gli_rs::GliImage

#[repr(transparent)]
pub struct GliImage { /* fields omitted */ }

GliImage representation for a single texture level.

Methods

impl GliImage

pub fn new(format: Format, extent: Extent3d) -> GliImage

Create an image object and allocate an image storage for it.

pub fn new_empty() -> GliImage

Create an empty image instance.

pub fn share_from(image: &GliImage, format: Format) -> GliImage

Create an image object by sharing an existing image storage_linear from another image instance. This image object is effectively an image view where format can be reinterpreted with a different compatible image format. For formats to be compatible, the block size of source and destination must match.

pub fn clear(&mut self)

Clear the entire image storage_linear with zeros.

pub fn data(&self) -> *const c_void

Return a pointer to the beginning of the texture instance data.

pub unsafe fn data_mut(&mut self) -> *mut c_void

Return a mutable pointer to the beginning of the texture instance data.

pub fn empty(&self) -> bool

Return whether the image instance is empty, no storage_linear or description have been assigned to the instance.

pub fn extent(&self) -> Extent3d

Return the dimensions of an image instance: width, height and depth.

pub fn format(&self) -> Format

Return the image instance format.

pub fn size(&self) -> usize

Return the memory size of an image instance storage_linear in bytes.

Trait Implementations

impl Eq for GliImage

impl PartialEq<GliImage> for GliImage

fn eq(&self, other: &GliImage) -> bool

Compare two images. Two images are equal when the data is the same.

fn ne(&self, other: &GliImage) -> bool

Compare two images. Two images are equal when the date is the same.
