NAME
im_makerw - make an IMAGE writeable
SYNOPSIS
#include <vips/vips.h> int im_makerw( image ) IMAGE *image;
DESCRIPTION
im_makerw(3) attempts to make image writeable, ready for an in-place
operation. Its actions are just as those for im_incheck(3), except
that descriptors which after im_incheck(3) end up as IM_MMAPIN descriptors, magically become IM_MMAPINRW descriptors.
Extreme caution is urged! You can permanently damage valuable data with
this call.
