# lqr\_carver\_set\_preserve\_input\_image(3)

set a flag to preserve the buffer passed to a LqrCarver object upon creation

## NAME

lqr\_carver\_set\_preserve\_input\_image - set a flag to preserve the buffer passed to a LqrCarver object upon creation

## SYNOPSIS

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

**void lqr\_carver\_set\_preserve\_input\_image(LqrCarver\*** *carver***);**

## DESCRIPTION

The function **lqr\_carver\_set\_preserve\_input\_image** flags the LqrCarver object pointed to by *carver* so that it does not alter in any way the buffer which is passed to it by the constructor. It must be used before any resizing-related operation takes place, either after the *carver* construction or after the calls to [**lqr\_carver\_init**(3)](/lqr_carver_init/3.md) or [**lqr\_vmap\_load**(3)](/lqr_vmap_load/3.md).

## SEE ALSO
