The built-in image function calls to read and write images are supported.. The generic type gentype is used to indicate the built-in data types char, uchar, short, ushort, int, uint, long, ulong, or float. The generic type OpenCL Specification. Creating, reading and writing a Image2D variable with OpenCLTemplate is as follows: float matrix is used to choose pixel format and data type. This means.
The following table describes other data types supported by OpenCL: NOTE: The image2d_t, image3d_t, image2d_array_t, image1d_t, image1d_buffer_t. I am trying to use OpenCL and image2d_t objects to speed up image convolution . When I noticed that the output was a blank image of all zeros.
read_imagef returns floating-point values in the range [ The read_imagef calls that take integer coordinates must use a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to OpenCL Specification . float4 read_imagef (, image2d_array_t image,. int4 coord) float4 read_imagef (, image2d_array_depth_t image,. int4 coord) .. OpenCL Specification.
