◆ find_color()

uint8_t find_color ( const char *  name)

Finds a color by name.

Parameters
namecolor name, case-sensitive.
Returns
the matching color in the coloralias if found, 0 otherwise.
Note
0 will actually be black, so there is no way the calling function can tell if an error occurred or not

int find_smooth ( const Face face,

Find the smooth face for a given face.

Parameters

Returns
1=smooth face found, 0=no smooth face found

◆ get_face_fallback()

int get_face_fallback ( int  faceset,
uint16_t  imageno 
)

This returns the set we will actually use when sending a face. This is used because the image files may be sparse. This function is recursive. imageno is the face number we are trying to send

If face is not found in specified faceset, tries with 'fallback' faceset.

Parameters
facesetfaceset to check
imagenoimage number

Variable Documentation

◆ blank_face

const Face* blank_face

◆ colorname

const char* const colorname[]
static
Initial value:
= {
"black",
"white",
"blue",
"red",
"orange",
"light_blue",
"dark_orange",
"green",
"light_green",
"grey",
"brown",
"yellow",
"khaki"
}

The only thing this table is used for now is to translate the colorname in the magicmap field of the face into a numeric index that is then sent to the client for magic map commands. The order of this table must match that of the NDI colors in include/newclient.h.
