The data is assumed to be an array of floats. - By default there are three floats per pixel in the order red, green, blue. - (RGBE_DATA_??? values control this.) Only the mimimal header reading and - writing is implemented. Each routine does error checking and will return - a status value as defined below. This code is intended as a skeleton so - feel free to modify it to suit your needs. <P> - - Ported to Java and restructured by Kenneth Russell. <BR> - posted to http://www.graphics.cornell.edu/~bjw/ <BR> - written by Bruce Walter ([email protected]) 5/26/95 <BR> - based on code written by Greg Ward <BR> -*/ - -public class RGBE { - // Flags indicating which fields in a Header are valid - private static final int VALID_PROGRAMTYPE = 0x01; - private static final int VALID_GAMMA = 0x02; - private static final int VALID_EXPOSURE = 0x04; - - private static final String gammaString = "GAMMA="; - private static final String exposureString = "EXPOSURE="; - - private static final Pattern widthHeightPattern = Pattern.compile("-Y (\\d+) \\+X (\\d+)"); - - public static class Header { - // Indicates which fields are valid - private int valid; - - // Listed at beginning of file to identify it after "#?". - // Defaults to "RGBE" - private String programType; - - // Image has already been gamma corrected with given gamma. - // Defaults to 1.0 (no correction) - private float gamma; - - // A value of 1.0 in an image corresponds to <exposure> - // watts/steradian/m^2.
