			'''SincLin2Resize''' is a high-quality resizer that supplements SincResize, designed to maintain performance with increased sinc taps for minimal artifacts. This is a version of SincResize with a workaround for the 'kernel edge computing issue' present in the original SincResize kernel. It is slightly sharper compared to other weighted sinc kernels with the same number of taps (such as Lanczos or Blackman). To suppress computing errors below 1 LSB of 8-bit, a recommended number of taps is greater than 3 or 4. Using too few taps may still expose this issue. For higher precision computing (greater than 8-bit per sample), the minimum number of taps required to shift residual computing errors below 1 LSB may be higher.

			float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'', float ''p'', int ''force'', bool ''keep_center'', string ''placement'' ] )
			}}

			'''SinPowerResize''' is an easy-to-adjust resizer with a single control parameter, perfect for downsampling and creating content conditioned to reduce aliasing and ringing. Both SinPow and UserDefined2 resizers allow control over the acutance effect of the output while minimizing excessive ringing (within a certain range of control parameters). Acutance of the Gauss kernel can be considered the 'zero level,' whereas for SinPow and UserDefined2, it can be greater than zero, depending on the control parameters.

			== UserDefined2Resize ==
			<div style="max-width:62em" >
			{{FuncDef
			\|UserDefined2Resize(clip ''clip'', int ''target_width'', int ''target_height'' [, float ''b'', float ''c'', float ''s'', <br>
			float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'', int ''force'', bool ''keep_center'', string ''placement'' ] )
			}}

			'''UserDefined2Resize''' is a versatile resizer offering fine control over sharpness and ringing, ideal for downsampling and high-quality antialiasing with adjustable parameters.
