write_imagef can only be used with image objects created with image_channel_data_type set to one of the
pre-defined packed formats or set to CL_SNORM_INT8, CL_UNORM_INT8, CL_SNORM_INT16, CL_UNORM_INT16,
CL_HALF_FLOAT or CL_FLOAT. Appropriate data format conversion will be done to convert channel data from a
floating-point value to actual data format in which the channels are stored.
write_imagei can only be used with image objects created with image_channel_data_type set to one of the
following values: CL_SIGNED_INT8, CL_SIGNED_INT16, and CL_SIGNED_INT32.
write_imageui functions can only be used with image objects created with image_channel_data_type set to
one of the following values: CL_UNSIGNED_INT8, CL_UNSIGNED_INT16, or CL_UNSIGNED_INT32.
An application that wants to use half and halfn types will need to include the #pragma OPENCL EXTENSION
cl_khr_fp16(3clc) : enable directive.
write_imageh can only be used with image objects created with image_channel_data_type set to one of the
pre-defined packed formats or set to CL_SNORM_INT8, CL_UNORM_INT8, CL_SNORM_INT16, CL_UNORM_INT16 or
CL_HALF_FLOAT. Functions that take image2d_t.PP For the functions that take an image_2d_t image, write
color value to location specified by coord.xy in the 2D image object specified by image. Appropriate data
format conversion to the specified image format is done before writing the color value. coord.x and
coord.y are considered to be unnormalized coordinates and must be in the range 0 ... image width - 1, and
0 ... image height - 1.
For functions that take image_2d_t, the behavior of write_imagef, write_imagei, write_imageui, and
write_imageh for image objects created with image_channel_data_type values not specified in the
description above or with (x,y) coordinate values that are not in the range (0 ... image width - 1, 0
... image height - 1), respectively, is undefined. Functions that take image2d_array_t.PP For the
functions that take an image_2d_array_t image, write color value to location specified by coord.xy in the
2D image identified by coord.z in the 2D image array specified by image. Appropriate data format
conversion to the specified image format is done before writing the color value. coord.x, coord.y and
coord.z are considered to be unnormalized coordinates and must be in the range 0 ... image width - 1, 0
... image height - 1 and 0 ... image number of layers - 1.
For functions that take image_2d_array_t, the behavior of write_imagef, write_imagei, write_imageui, and
write_imageh for image objects created with image_channel_data_type values not specified in the
description above or with (x,y,z) coordinate values that are not in the range (0 ... image width - 1, 0
... image height - 1), respectively, is undefined.
