Module sampler

A sampler object describes how to sample an image when the image is read in the kernel. The built-in functions to read from an image in a kernel take a sampler as an argument. The sampler arguments to the image read function can be sampler objects created using OpenCL functions and passed as argument values to the kernel or can be samplers declared inside a kernel.

create_sampler

create_sampler_with_properties

context must be a valid OpenCL context.sampler_properties specifies a list of sampler property names and their corresponding values. Each sampler property name is immediately followed by the corresponding desired value. The list is terminated with 0. The list of supported properties is described in the Sampler Properties table. If a supported property and its value is not specified in sampler_properties, its default value will be used. sampler_properties can be NULL in which case the default values for supported sampler properties will be used.
