Chapter 8. Images and Samplers

In the previous chapter, we introduced memory objects that are used to read, write, and copy memory to and from an OpenCL device. In this chapter, we introduce the image object, a specialized type of memory object that is used for accessing 2D and 3D image data. This chapter walks through an example of using image and sampler objects and introduces the following concepts:

• Overview of image and sampler objects

• Creating image and sampler objects

• Specifying and querying for image formats

• OpenCL C functions for working with images

• Transferring image object data
