# lqr\_carver\_init(3)

activates an LqrCarver object

## NAME

lqr\_carver\_init - activates an LqrCarver object

## SYNOPSIS

```
#include <lqr.h>
```

**LqrRetVal lqr\_carver\_init(LqrCarver\*** *carver***, gint** *delta\_x***, gfloat** *rigidity***);**

## DESCRIPTION

The function **lqr\_carver\_init** initialises the LqrCarver pointed to by *carver*, so that it can compute the visibility maps as needed upon calls of **lqr\_carver\_resize**.

The parameter *delta\_x* controls the maximum transversal step a seam can make. A value of 0 means straight seams. Normally, it is set to 1.

The parameter *rigidity* can be used to add a negative bias to non-straight seams, and it is normally set to 0.

Visibility maps must not be loaded with the function **lqr\_vmap\_load** when using this function, neither before nor after invoking it.

## RETURN VALUE

The return value follows the Liquid Rescale library signalling system.
