A 16-bit luminance is interpreted + * as a sign bit followed by a 15-bit integer that is converted + * to and from a linear magnitude using the transformation: + * + * L = 2^( (Le+.5)/256 - 64 ) # real from 15-bit + * + * Le = floor( 256*(log2(L) + 64) ) # 15-bit from real + * + * The actual conversion to world luminance units in candelas per sq. meter + * requires an additional multiplier, which is stored in the TIFFTAG_STONITS. + * This value is usually set such that a reasonable exposure comes from + * clamping decoded luminances above 1 to 1 in the displayed image. + * + * The 16-bit values for u and v may be converted to real values by dividing + * each by 32768. (This allows for negative values, which aren't useful as + * far as we know, but are left in case of future improvements in human + * color vision.) + * + * Conversion from (u,v), which is actually the CIE (u',v') system for + * you color scientists, is accomplished by the following transformation: + * + * u = 4*x / (-2*x + 12*y + 3) + * v = 9*y / (-2*x + 12*y + 3) + * + * x = 9*u / (6*u - 16*v + 12) + * y = 4*v / (6*u - 16*v + 12) + * + * This process is greatly simplified by passing 32-bit IEEE floats + * for each of three CIE XYZ coordinates. The codec then takes care + * of conversion to and from LogLuv, though the application is still + * responsible for interpreting the TIFFTAG_STONITS calibration factor. + * + * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white + * point of (x,y)=(1/3,1/3). However, most color systems assume some other + * white point, such as D65, and an absolute color conversion to XYZ then + * to another color space with a different white point may introduce an + * unwanted color cast to the image. It is often desirable, therefore, to + * perform a white point conversion that maps the input white to [1 1 1] + * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT + * tag value. A decoder that demands absolute color calibration may use + * this white point tag to get back the original colors, but usually it + * will be ignored and the new white point will be used instead that + * matches the output color space. + * + * Pixel information is compressed into one of two basic encodings, depending + * on the setting of the compression tag, which is one of COMPRESSION_SGILOG + * or COMPRESSION_SGILOG24. For COMPRESSION_SGILOG, greyscale data is + * stored as: + * + * 1 15 + * |-+---------------| + * + * COMPRESSION_SGILOG color data is stored as: + * + * 1 15 8 8 + * |-+---------------|--------+--------| + * S Le ue ve + * + * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as: + * + * 10 14 + * |----------|--------------| + * Le' Ce + * + * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is + * encoded as an index for optimal color resolution. The 10 log bits are + * defined by the following conversions: + * + * L = 2^((Le'+.5)/64 - 12) # real from 10-bit + * + * Le' = floor( 64*(log2(L) + 12) ) # 10-bit from real + * + * The 10 bits of the smaller format may be converted into the 15 bits of + * the larger format by multiplying by 4 and adding 13314. Obviously, + * a smaller range of magnitudes is covered (about 5 orders of magnitude + * instead of 38), and the lack of a sign bit means that negative luminances + * are not allowed. (Well, they aren't allowed in the real world, either, + * but they are useful for certain types of image processing.) + * + * The desired user format is controlled by the setting the internal + * pseudo tag TIFFTAG_SGILOGDATAFMT to one of: + * SGILOGDATAFMT_FLOAT = IEEE 32-bit float XYZ values + * SGILOGDATAFMT_16BIT = 16-bit integer encodings of logL, u and v + * Raw data i/o is also possible using: + * SGILOGDATAFMT_RAW = 32-bit unsigned integer with encoded pixel + * In addition, the following decoding is provided for ease of display: + * SGILOGDATAFMT_8BIT = 8-bit default RGB gamma-corrected values + * + * For grayscale images, we provide the following data formats: + * SGILOGDATAFMT_FLOAT = IEEE 32-bit float Y values + * SGILOGDATAFMT_16BIT = 16-bit integer w/ encoded luminance + * SGILOGDATAFMT_8BIT = 8-bit gray monitor values + * + * Note that the COMPRESSION_SGILOG applies a simple run-length encoding + * scheme by separating the logL, u and v bytes for each row and applying + * a PackBits type of compression.
