NAME
pnmenlarge - read a portable anymap and enlarge it N times
SYNOPSIS
pnmenlarge _✓N [_✓p_✓n_✓m_✓f_✓i_✓l_✓e]
DESCRIPTION
Reads a portable anymap as input. Replicates its pixels _✓N
times, and produces a portable anymap as output.
_✓p_✓n_✓m_✓e_✓n_✓l_✓a_✓r_✓g_✓e can only enlarge by integer factors. The slower
but more general _✓p_✓n_✓m_✓s_✓c_✓a_✓l_✓e can enlarge or reduce by arbitrary
factors, and _✓p_✓b_✓m_✓r_✓e_✓d_✓u_✓c_✓e can reduce by integer factors, but
only for bitmaps.
If you enlarge by a factor of 3 or more, you should probably
add a _✓p_✓n_✓m_✓s_✓m_✓o_✓o_✓t_✓h step; otherwise, you can see the original
pixels in the resulting image.
