public javax.media.Format	intersects(javax.media.Format format) Find the common attributes of two matching formats. If the given format does not match this one, the result is undefined. Otherwise, it returns a format object with its attributes set to the common attributes of the two. return a format object with its attributes set to the common attributes of the two. see matches Format fmt; if ((fmt = super.intersects(format)) == null) return null; if (!(format instanceof AviVideoFormat)) return fmt; AviVideoFormat other = (AviVideoFormat)format; AviVideoFormat res = (AviVideoFormat)fmt; res.planes = (planes != NOT_SPECIFIED ? planes : other.planes); res.bitsPerPixel = (bitsPerPixel != NOT_SPECIFIED ? bitsPerPixel : other.bitsPerPixel); res.imageSize = (imageSize != NOT_SPECIFIED ? imageSize : other.imageSize); res.xPelsPerMeter = (xPelsPerMeter != NOT_SPECIFIED ? xPelsPerMeter : other.xPelsPerMeter); res.yPelsPerMeter = (yPelsPerMeter != NOT_SPECIFIED ? yPelsPerMeter : other.yPelsPerMeter); res.clrUsed = (clrUsed != NOT_SPECIFIED ? clrUsed : other.clrUsed); res.clrImportant = (clrImportant != NOT_SPECIFIED ? clrImportant : other.clrImportant); res.codecSpecificHeader = (codecSpecificHeader != null ? codecSpecificHeader : other.codecSpecificHeader); return res;
public boolean	matches(javax.media.Format format) Test to see if the given format matches this format. Matches compares attributes that are defined and ignore attributes that are unspecified. Two formats do not have to be of the same class to be considered a match. Say "A" are "B" are the two classes. If "A" derives "B" or "B" derives "A", then a match is possible (after comparing individual attributes. Otherwise, matches fails. This is to prevent matching VideoFormat and AudioFormat, for example. return true if the given format matches this one. if (!super.matches(format)) return false; if (!(format instanceof AviVideoFormat)) return true; AviVideoFormat other = (AviVideoFormat) format; boolean returnVal = (planes == NOT_SPECIFIED || other.planes == NOT_SPECIFIED || planes == other.planes) && (bitsPerPixel == NOT_SPECIFIED || other.bitsPerPixel == NOT_SPECIFIED || bitsPerPixel == other.bitsPerPixel) && (imageSize == NOT_SPECIFIED || other.imageSize == NOT_SPECIFIED || imageSize == other.imageSize) && (xPelsPerMeter == NOT_SPECIFIED || other.xPelsPerMeter == NOT_SPECIFIED || xPelsPerMeter == other.xPelsPerMeter) && (yPelsPerMeter == NOT_SPECIFIED || other.yPelsPerMeter == NOT_SPECIFIED || yPelsPerMeter == other.yPelsPerMeter) && (clrUsed == NOT_SPECIFIED || other.clrUsed == NOT_SPECIFIED || clrUsed == other.clrUsed) && (clrImportant == NOT_SPECIFIED || other.clrImportant == NOT_SPECIFIED || clrImportant == other.clrImportant) && (codecSpecificHeader == null || other.codecSpecificHeader == null || codecSpecificHeader == other.codecSpecificHeader || codecSpecificHeader.equals(codecSpecificHeader)); return returnVal;
