| ☜ | MWAPI - ColorsDraft MDC Standard | ☞ | ||||
Color specifications have three components: a red value, a green value, and a blue value.
| color | ::= | expr | V | │ │ │ |
rcolor , gcolor , bcolor emptystring |
│ │ │ |
| rcolor | ::= | intlit |
| gcolor | ::= | intlit |
| bcolor | ::= | intlit |
identifies a specific color. rcolor specifies the amount of red, gcolor specifies the amount of green, and bcolor specifies the amount of blue. rcolor, gcolor, and bcolor values are restricted to a range of 0, meaning no color, through 65535, meaning full color.
A color value of "0,0,0" signifies black; a color value of "65535,65535,65535" indicates white; and a color value with identical rcolor, gcolor, and bcolor values signifies a shade of grey.
Appropriate scaling from the 0 to 65535 range to the color domain of the underlying windowing platform or hardware is performed automatically by the MWAPI.
A color value of the form emptystring indicates that the appropriate default color from the underlying windowing platform should be used. If the underlying windowing platform does not provide an appropriate default, the color is determined by the MWAPI implementation.
