- NAME
- pnmdepth - change the maxval in a portable anymap
-
- SYNOPSIS
- pnmdepth _✓n_✓e_✓w_✓m_✓a_✓x_✓v_✓a_✓l [_✓p_✓n_✓m_✓f_✓i_✓l_✓e]
-
- DESCRIPTION
- Reads a portable anymap as input. Scales all the pixel
- values, and writes out the image with the new maxval. Scal-
- ing the colors down to a smaller maxval will result in some
- loss of information.
-
- Be careful of off-by-one errors when choosing the new max-
- val. For instance, if you want the color values to be five
- bits wide, use a maxval of 31, not 32.
