<p><i>Tiff2rgba</i> converts a wide variety of TIFF images |
|
52 |
into an RGBA TIFF image. This includes the ability to |
|
53 |
translate different color spaces and photometric |
|
54 |
interpretation into RGBA, support for alpha blending, and |
|
55 |
translation of many different bit depths into a 32bit RGBA |
|

image.</p> |

<p>Internally this program is implemented using the |

59 |
<i>TIFFReadRGBAImage()</i> function, and it suffers any |
|
60 |
limitations of that image. This includes limited support for |
|
61 |
> 8 BitsPerSample images, and flaws with some esoteric |
|
62 |
combinations of BitsPerSample, photometric interpretation, |
|
63 |
block organization and planar configuration.</p> |
