Hi, I am pretty much new to OpenCL. I wantto read a jpeg image file into the kernel, do some processing, get the results back to the host and output the image file into some other location. I am facing somedifficulties doing this.
When using the clCreateImage2D,I need to specify the size of the image manually. Is there a way that I can get the size of the image from some routines and pass them tothis function.?
AlsoI need to understandwhatthe "host ptr" arguement(last but second arguement) exactly meansthat theclCreateImage2D routinetakes. Isit like we can specify thelocation of the image directly ?
