| al@19641 | 22 ------- |
| al@19641 | 23 |
| al@19641 | 24 * -t 128 : will set the transparency threshold level as 128, so pixels with |
| al@19641 | 25 alpha level less than 128 will become fully transparent. |
| al@19641 | 26 * -b "#ff0000" -b 255 0 0 : will set the background color as red, so |
| al@19641 | 27 partially transparent pixels will be composed over red. |
| al@19641 | 28 When -b is used, -t is ignored. |
| al@19641 | 29 |
