When the masked color number is encountered, a mask is set up, the same size of the screen image. How this operates 'under the hood' is somewhat like double buffering. To avoid this, you can plot a semi-transparent color value using a color mask. This is due to the alpha channel value being applied twice to the same set of pixels. When filling such an area on the plot using a semi-transparent color, spurious lines may appear at the polygon boundaries or in areas where the polygons overlap. The filled areas usually consist of a large number of polygons that appear as one solid region.

Starting with GrADS version 2.1, there is an addional optional argument that may be used to set a transparency level for a user-defined color.ДЄ filled region on a plot is achieved by shaded contouring, filling land/ocean areas using basemap.gs, or drawing a shapefile with filled polygons.

Functions (Visual Basic for Applications).

MyObject.Color = RGB(255, 0, 0) ' Set the Color property of MyObject to Red. Red = RGB(255, 0, 0) ' Return the value for Red. If MyObject does not exist, or if it does not have a Color property, an error occurs. The object MyObject and its property are used for illustration purposes only. It is used for those application methods and properties that accept a color specification. This example shows how the RGB function is used to return a whole number representing an RGB color value. They may be used within the context of Microsoft applications for the Macintosh, but should not be used when communicating color changes directly to the Macintosh operating system. The RGB color values returned by this function are incompatible with those used by the Macintosh operating system. The following table lists some standard colors and the red, green, and blue values they include: Color The value for any argument to RGB that exceeds 255 is assumed to be 255. An RGB color value specifies the relative intensity of red, green, and blue to cause a specific color to be displayed. Number in the range 0вЂ“255, inclusive, that represents the blue component of the color.ДЄpplication methods and properties that accept a color specification expect that specification to be a number representing an RGB color value. Number in the range 0вЂ“255, inclusive, that represents the green component of the color. Number in the range 0вЂ“255, inclusive, that represents the red component of the color. The RGB function syntax has these named arguments: Part Returns a Long whole number representing an RGB color value.
