dump_faces()

void dump_faces

(

Dump all faces to stderr, for debugging purposes.

find_color()

uint8_t find_color

(

const char *

name

)

Finds a color by name.

Parameters

name	color 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

find_smooth()

int find_smooth	(	const Face *	face,
		const Face **	smoothed
	)

Find the smooth face for a given face.

Parameters

face	the face to find the smoothing face for
smoothed	return value: set to smooth face

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

faceset	faceset to check
imageno	image number

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.
