Implementations

impl Texture

pub fn empty() -> Texture

pub fn gl_internal_id(&self) -> GLuint

pub fn delete(&self)

Delete GPU texture, leaving handle unmodified.

More high-level code on top of oxid probably is going to call this in Drop implementation of some more RAII buffer object.

There is no protection against using deleted textures later. However its not an UB in OpenGl and thats why this function is not marked as unsafe

impl Texture

pub fn new_render_texture(ctx: &mut Context, params: TextureParams) -> Texture

Shorthand for new(ctx, TextureAccess::RenderTarget, params)

pub fn new(
    ctx: &mut Context,
    _access: TextureAccess,
    bytes: Option<&[u8]>,
    params: TextureParams
) -> Texture

pub fn from_data_and_format(
    ctx: &mut Context,
    bytes: &[u8],
    params: TextureParams
) -> Texture

Upload texture to GPU with given TextureParams

pub fn from_rgba8(
    ctx: &mut Context,
    width: u16,
    height: u16,
    bytes: &[u8]
) -> Texture

Upload RGBA8 texture to GPU

pub fn set_filter(&self, ctx: &mut Context, filter: FilterMode)

pub fn resize(
    &mut self,
    ctx: &mut Context,
    width: u32,
    height: u32,
    bytes: Option<&[u8]>
)

pub fn update(&self, ctx: &mut Context, bytes: &[u8])

Update whole texture content bytes should be width * height * 4 size - non rgba8 textures are not supported yet anyway

pub fn update_texture_part(
    &self,
    ctx: &mut Context,
    x_offset: i32,
    y_offset: i32,
    width: i32,
    height: i32,
    bytes: &[u8]
)

pub fn read_pixels(&self, bytes: &mut [u8])

Read texture data into CPU memory

Trait Implementations

impl Clone for Texture

fn clone(&self) -> Texture

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Texture

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Texture> for Texture

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
