## Constructor & Destructor Documentation

## ◆ Image2D() [1/5]

cl::Image2D::Image2D | ( | const Context & | context,
|  | cl_mem_flags | flags,
|  | ImageFormat | format,
|  | size_type | width,
|  | size_type | height,
|  | size_type | row_pitch = 0,
|  | void * | host_ptr = nullptr,
|  | cl_int * | err = nullptr )
| inline

Constructs a 2D Image in a specified context.

Wraps clCreateImage().

Definition at line 4990 of file opencl.hpp.

## ◆ Image2D() [2/5]

cl::Image2D::Image2D | ( | const Context & | context,
|  | ImageFormat | format,
|  | const Buffer & | sourceBuffer,
|  | size_type | width,
|  | size_type | height,
|  | size_type | row_pitch = 0,
|  | cl_int * | err = nullptr )
| inline

Constructs a 2D Image from a buffer.

Note
  This will share storage with the underlying buffer.

Requires OpenCL 2.0 or newer or OpenCL 1.2 and the cl_khr_image2d_from_buffer extension.

Wraps clCreateImage().

Definition at line 5061 of file opencl.hpp.

## ◆ Image2D() [3/5]

cl::Image2D::Image2D | ( | const Context & | context,
|  | cl_channel_order | order,
|  | const Image & | sourceImage,
|  | cl_int * | err = nullptr )
| inline

Constructs a 2D Image from an image.

Note
  This will share storage with the underlying image but may reinterpret the channel order and type.

The image will be created matching with a descriptor matching the source.

Parameters

  order | is the channel order to reinterpret the image data as. The channel order may differ as described in the OpenCL 2.0 API specification.

Wraps clCreateImage().

Definition at line 5107 of file opencl.hpp.

## ◆ Image2D() [4/5]

cl::Image2D::Image2D | ( |  | ) |
| inline

Default constructor - initializes to nullptr.

Definition at line 5158 of file opencl.hpp.

## ◆ Image2D() [5/5]

cl::Image2D::Image2D | ( | const cl_mem & | image2D,
|  | bool | retainObject = false )
| inlineexplicit

Constructor from cl_mem - takes ownership.

Parameters

  retainObject | will cause the constructor to retain its cl object. Defaults to false to maintain compatibility with earlier versions. See Memory for further details.

Definition at line 5167 of file opencl.hpp.

## Member Function Documentation

## ◆ operator=()

Image2D & cl::Image2D::operator= | ( | const cl_mem & | rhs | ) |
| inline

Assignment from cl_mem - performs shallow copy.

See Memory for further details.
