the rgbquad structure describes a color consisting of relative intensities

of
red, green, and blue. the bmicolors member of the bitmapinfo structure
consists of an array of rgbquad structures.

member description

rgbblue specifies the intensity of blue in the color.
rgbgreenspecifies the intensity of green in the color.
rgbred specifies the intensity of red in the color.
rgbreserved not used; must be set to zero.

rgb (2.x)

colorref rgb(cred, cgreen, cblue)

byte cred; /* red component of color */
byte cgreen; /* green component of color */
byte cblue; /* blue component of color */

the rgb macro selects an rgb color based on the parameters supplied and the
color capabilities of the output device.

parameter description

cred specifies the intensity of the red color field.
cgreen specifies the intensity of the green color field.
cblue specifies the intensity of the blue color field.

returns

the return value specifies the resultant rgb color.

comments

the intensity for each argument can range from 0 through 255. if all three
intensities are specified as zero, the result is black. if all three
intensities are specified as 255, the result is white.

comments

the rgb macro is defined in windows.h as follows:

#define rgb(r,g,b) ((colorref)(((byte)(r)|((word)(g)<<8))| \
(((dword)(byte)(b))<<16)))

bitmapcoreinfo (3.0)

typedef struct tagbitmapcoreinfo { /* bmci */
bitmapcoreheader bmciheader;
rgbtriple bmcicolors[1];
} bitmapcoreinfo;

the bitmapcoreinfo structure fully defines the dimensions and color
information for a device-independent bitmap (dib). windows applications
should use the bitmapinfo structure instead of bitmapcoreinfo whenever
possible.

member description

bmciheader specifies a bitmapcoreheader structure that contains
information about the dimensions and color format of a dib.

bmcicolors specifies an array of rgbtriple structures that define the
colors in the bitmap.

comments

the bitmapcoreinfo structure describes the dimensions and colors of a

bitmap.
it is followed immediately in memory by an array of bytes which define the
pixels of the bitmap. the bits in the array are packed together, but each
scan line must be zero-padded to end on a long boundary. segment boundaries,
however, can appear anywhere in the bitmap. the origin of the bitmap is the
lower-left corner.

the bcbitcount member of the bitmapcoreheader structure determines the

number
of bits that define each pixel and the maximum number of colors in the
bitmap. this member may be set to any of the following values:

value meaning

1 the bitmap is monochrome, and the bmcicolors member must contain two
entries. each bit in the bitmap array represents a pixel. if the bit is
clear, the pixel is displayed with the color of the first entry in the
