Member Function Documentation

void RollCount::param (  int  fps, int  from, int  digits, int  groupspacing = 5, RGBA *  background = NULL, int  marginx = 0, int  marginy = 0, int  shift = 0, int  digitsize = 0 )  [inline]

Parameters: fps  Specify the framerate that next() will be called with. This value must be correct, or the seconds will be too long or too short. from  The initial value, in seconds, of the counter. digits  Number of digits shown. groupspacing  Extra space, in pixels, between pairs of digits (e.g. in a time value like 2:03:58). background  An RGBA image that will be shown behind the counter always. When using this, it will only look right if digits, groupspacing, marginx, marginy and digitsize are tuned to suit this image. marginx,marginy  Where to place the counter inside the background, if one is given. Otherwise these parameters are ignored. shift  The number of frames that the digits to the left will lag behind those to the right. This makes it look more mechanical when multiple digits are changing. digitsize  The font size for printing the digits. When it has to match a background, this is best given as a negative value, which is interpreted as absolute.
