Detailed Description

Basic function to simulate a scale layer.

This function calls the following OpenCL kernels:

  1. kernels::ClScaleKernel

Definition at line 39 of file ClScale.h.

◆ configure()

void configure ( const CLCompileContext compile_context,
ITensorInfo src,
ITensorInfo dst,
const ScaleKernelInfo info 
)

Initialize the function's source, destination, interpolation type and border_mode.

Parameters
[in]compile_contextThe compile context to be used.
[in,out]srcSource tensor info. Data types supported: U8/QASYMM8/QASYMM8_SIGNED/S16/F16/F32. (Written to only for border_mode != UNDEFINED)
[out]dstDestination tensor info. Data types supported: Same as src All but the lowest two dimensions must be the same size as in the input tensor, i.e. scaling is only performed within the XY-plane.
[in]infoScaleKernelInfo descriptor to be used to configure
