| 51 | <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 | |
| 56 | image.</p> | |
| 57 | <!-- INDENTATION --> | |
| 58 | <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> | |
| 64 | <!-- INDENTATION --> | |
| 65 | <p>The generated images are stripped images with four | |
| 66 | samples per pixel (red, green, blue and alpha) or if the -n | |
| 67 | flag is used, three samples per pixel (red, green, and | |
| 68 | blue). The resulting images are always planar configuration | |
| 69 | contiguous. For this reason, this program is a useful | |
| 70 | utility for transform exotic TIFF files into a form | |
| 71 | ingestible by almost any TIFF supporting software.</p> | |
