|
|
function rgbToColor {
|
|
echo $(( $(($1<<16)) + $(($2<<8)) + $(($3)) ));
|
|
}
|
|
|
|
function colorToRGB {
|
|
echo "Red: $(($1>>16&0xff))"
|
|
echo "Green: $(($1>>8&0xff))"
|
|
echo "Blue: $(($1&0xff))"
|
|
}
|
|
```
|
|
#### Example
|
|
RGB Value to color uint32_t
|
|
```bash

|
bash$ rgbToColor 155 230 32
|
|
10216992
|
|
bash$

|
Red: 155
|
|
Green: 230
