xtrans

uint8_t dt_iop_buffer_dsc_t::xtrans[6][6]

filter for Fuji X-Trans images, only used if filters == 9u. The coefficients in the filter represent the channel (R, G, B) associated with a pixel spatial coordinate. The filter itself is a 6x6 tile that we shift on the image, starting at the top-left corner, when demosaicing, so we know what "color" we are looking at, at any given pixel coordinate, in the raw image. When images are cropped at the raw level, we need to shift the coefficients properly to take care of the phase shift introduced by trimming. See rawprepare.c:_update_output_cfa_descriptor()
