* Put the RGBA values that correspond to color_string in rgba_color. |
|
* |
|
* @param color_string a string specifying a color. It can be the name of |
|
* a color (case insensitive match) or a 0xRRGGBB[AA] sequence, |
|
* possibly followed by "@" and a string representing the alpha |
|
* component. |
|
* The alpha component may be a string composed by "0x" followed by an |
|
* hexadecimal number or a base-10 number between 0 and 255, or a |
|
* decimal number between 0.0 and 1.0, which represents the opacity |
|
* value (0/0x00/0.0 means completely transparent, 255/0xff/1.0 |
|
* completely opaque). |
|
* If the alpha component is not specified then 255 is assumed. |
|
* The string "random" will result in a random color. |
|
* @return >= 0 in case of success, a negative value in case of |
|
* failure (for example if color_string cannot be parsed). |
