Definition


#define DSP_CALC_SCALING_SIZE(value, ratio) ((u32)(value * (u32)(ratio * 1000) / 1000))
#define DSP_CALC_SCALING_SIZE_FX(value, ratio) ((u32)( value * (u32)(ratio * 1000 / 4096.0f) / 1000))

Description

DSP_CALC_SCALING_SIZE(value, ratio) Uses the DSP_Scaling* functions to calculate the results of scaling an image with width or height of size value by a factor of ratio (f32 value).
DSP_CALC_SCALING_SIZE_FX(value, ratio) Uses the DSP_ScalingFx* functions to calculate the results of scaling an image with width or height of size value by a factor of ratio (fx32 value).
