Struct ocl::Image

pub struct Image<E: OclPrm> { /* fields omitted */ }

A section of device memory which represents one or many images.

Use ::builder for an easy way to create. [UNIMPLEMENTED]

Methods

impl<E: OclPrm> Image<E>

fn supported_formats(context: &Context,
                     flags: MemFlags,
                     mem_obj_type: MemObjectType)
                     -> OclResult<Vec<ImageFormat>>

Returns a list of supported image formats.

fn builder() -> ImageBuilder<E>

Returns an ImageBuilder. This is the recommended method to create a new Image.

fn new(queue: &Queue,
       flags: MemFlags,
       image_format: ImageFormat,
       image_desc: ImageDescriptor,
       image_data: Option<&[E]>)
       -> OclResult<Image<E>>

Returns a new Image.

Prefer ::builder to create a new image.

fn from_gl_texture(queue: &Queue,
                   flags: MemFlags,
                   image_desc: ImageDescriptor,
                   texture_target: GlTextureTarget,
                   miplevel: cl_GLint,
                   texture: cl_GLuint)
                   -> OclResult<Image<E>>

Returns a new Image from an existant GL texture2D/3D.

fn from_gl_renderbuffer(queue: &Queue,
                        flags: MemFlags,
                        image_desc: ImageDescriptor,
                        renderbuffer: cl_GLuint)
                        -> OclResult<Image<E>>

Returns a new Image from an existant renderbuffer.

fn cmd(&self) -> ImageCmd<E>

Returns an image command builder used to read, write, copy, etc.

Run .enq() to enqueue the command.

fn read<'b>(&'b self, data: &'b mut [E]) -> ImageCmd<'b, E>

Returns an image command builder set to read.

Run .enq() to enqueue the command.

fn write<'b>(&'b self, data: &'b [E]) -> ImageCmd<'b, E>

Returns an image command builder set to write.

Run .enq() to enqueue the command.

fn set_default_queue<'a>(&'a mut self, queue: &Queue) -> &'a mut Image<E>

Changes the default queue.

Returns a ref for chaining i.e.:

image.set_default_queue(queue).write(....);

[NOTE]: Even when used as above, the queue is changed permanently, not just for the one call. Changing the queue is cheap so feel free to change as often as needed.

The new queue must be associated with a valid device.

fn default_queue(&self) -> &Queue

Returns a reference to the default queue.

fn dims(&self) -> &SpatialDims

Returns this image's dimensions.

fn pixel_count(&self) -> usize

Returns the total number of pixels in this image.

fn pixel_element_len(&self) -> usize

Returns the length of each pixel element.

fn element_count(&self) -> usize

Returns the total number of pixel elements in this image. Equivalent to its length.

fn info(&self, info_kind: ImageInfo) -> ImageInfoResult

Get information about this image.

fn mem_info(&self, info_kind: MemInfo) -> MemInfoResult

Returns info about this image's memory.

fn core_as_ref(&self) -> &MemCore

Returns a reference to the core pointer wrapper, usable by functions in the core module.

Methods from Deref<Target=MemCore>

unsafe fn as_ptr(&self) -> *mut c_void

Returns a pointer, do not store it.

Trait Implementations
