<p><i>Tiff2rgba</i> converts a wide variety of TIFF images
into an RGBA TIFF image. This includes the ability to
translate different color spaces and photometric
interpretation into RGBA, support for alpha blending, and
translation of many different bit depths into a 32bit RGBA
image.</p>
<!-- INDENTATION -->
<p>Internally this program is implemented using the
<i>TIFFReadRGBAImage()</i> function, and it suffers any
limitations of that image. This includes limited support for
&gt; 8 BitsPerSample images, and flaws with some esoteric
combinations of BitsPerSample, photometric interpretation,
block organization and planar configuration.</p>
<!-- INDENTATION -->
<p>The generated images are stripped images with four
samples per pixel (red, green, blue and alpha) or if the -n
flag is used, three samples per pixel (red, green, and
blue). The resulting images are always planar configuration
contiguous. For this reason, this program is a useful
utility for transform exotic TIFF files into a form
ingestible by almost any TIFF supporting software.</p>
