RLE_PUTROW(3)							 RLE_PUTROW(3)

NAME
       rle_putrow - Write a row (scanline) of data to an RLE file.

SYNOPSIS
       #include <rle.h>

       void rle_putrow( rows, length, the_hdr );
       rle_pixel ** rows;
       int length;
       rle_hdr * the_hdr;

DESCRIPTION
       Rle_putrow  is  called for each output scanline when creating an RLE(5)
       image.  Rows is an array of pointers to the pixel data  for  the	 color
       components of the scanline.  Rows should have the_hdr→ncolors elements.
       If an alpha channel is being saved, rows[-1] should point to the	 alpha
       channel data.  Length is the number of pixels in the scanline.  Rows[i]
       should point to the the_hdr→xmin element of the scanline.

       The function rle_row_alloc(3) will properly allocate memory for use  by
       rle_putrow.

BUGS
       Having the scanline indexed from xmin is an incredible botch.  Its ori‐
       gin  lies  in the deep dark history of the raster toolkit, and it seems
       it's too late to change it now.
