The following will take a PNG file with a bitdepth of 1, 2, or 8, and output
planar 2bpp data:
<div class="Pp"></div>
<div class="D1">$ rgbgfx -o out.2bpp in.png</div>
<div class="Pp"></div>
The following creates a planar 2bpp file with only unique tiles, and its tilemap
<i class="Pa" title="Pa">out.tilemap</i>:
<div class="Pp"></div>
<div class="D1">$ rgbgfx -T -u -o out.2bpp in.png</div>
<div class="Pp"></div>
The following will do nothing:
<div class="Pp"></div>
<div class="D1">$ rgbgfx in.png</div>
