||
| 35 | j2k_to_image - |
||
| 36 | This program reads in a jpeg2000 image and converts it to another |
||
| 37 | image type. It is part of the OpenJPEG library. |
||
| 38 | .SP |
||
| 39 | Valid input image extensions are |
||
| 40 | .B .j2k, .jp2, .j2c, .jpt |
||
| 41 | .SP |
||
| 42 | Valid output image extensions are |
||
| 43 | .B .bmp, .pgm, .pgx, .png, .pnm, .ppm, .raw, .tga, .tif \fR. For PNG resp. TIF it needs libpng resp. libtiff . |

||
| 86 | .SH REDUCTION |
||
| 87 | Set the number of highest resolution levels to be discarded. |
||
| 88 | The image resolution is effectively divided by 2 to the power of the number of discarded levels. The reduce factor is limited by the smallest total number of decomposition levels among tiles. |
||
| 89 | .SH TILES |
||
| 90 | Set the maximum number of quality layers to decode. If there are less quality layers than the specified number, all the quality layers are decoded. |
