.SH NAME

blend \- Perform linear interpolation between two values
.SH SYNOPSIS
.HP
.B loadrt blend [count=\fIN\fB|names=\fIname1\fB[,\fIname2...\fB]]
.SH FUNCTIONS
.TP
\fBblend.\fIN\fB\fR (requires a floating-point thread)

.SH PINS
.TP
.B blend.\fIN\fB.in1\fR float in \fR
First input.  If select is equal to 1.0, the output is equal to in1
.TP
.B blend.\fIN\fB.in2\fR float in \fR
Second input.  If select is equal to 0.0, the output is equal to in2
.TP
.B blend.\fIN\fB.select\fR float in \fR
Select input.  For values between 0.0 and 1.0, the output changes linearly from in2 to in1
.TP
.B blend.\fIN\fB.out\fR float out \fR
Output value.
.SH PARAMETERS
.TP
.B blend.\fIN\fB.open\fR bit rw \fR
If true, select values outside the range 0.0 to 1.0 give values outside the range in2 to in1.  If false, outputs are clamped to the the range in2 to in1
