|
190 | |

|
191 | "red" # named colour |
|
|
192 | "#f00" # simple rgb |
|
|

|
|
194 | "TekHVC:300/50/50" # anything goes |
|
|
195 | |
|
|
196 | OR as an array reference with one, three or four components: |
|
|
197 | |
|
|
198 | [0.5] # 50% gray, 100% alpha |
|
|
199 | [0.5, 0, 0] # dark red, no green or blur, 100% alpha |

917 | First multiplies the pixels by C<$mul>, then adds C<$add>. This can be used |
|
|
918 | to implement brightness and contrast at the same time, with a wider value |
