DSP CalcScalingFactor*

Definition


f32 DSP_CalcScalingFactorF32(
		const u16 src_size,
		const u16 dst_size
	);

fx32 DSP_CalcScalingFactorFx32(
		const u16 src_size,
		const u16 dst_size
	);

Arguments

src_size Source data size for scaling.
dst_size Desired size for the output data after scaling.

Return Values

A factor that was reverse-calculated from, and uses the same type as, the specified values.

Description

Performs reverse calculations to get the factor for arguments specified with the desired output size from the DSP_Scaling* and DSP_ScalingFx* functions. The result and the arguments have the same type.

Due to factor restrictions (31–0.001), however, the correct factor may not be obtainable for some specified input and output sizes.
