    250250Another variant should enable us to specify which band correspond to the r, the g and the b:
    251251
    252 ST_AsJPEG(raster, integer, integer, integer) - raster, rband, gband, bband, quality=75
     252ST_AsJPEG(raster, integer, integer, integer) - raster, rband, gband, bband, quality=75[[BR]]
    253253ST_AsJPEG(raster, integer, integer, integer, integer) - raster, rband, gband, bband, quality
    254254
    … …  
    259259Another series should allow converting 1 band raster with pixel of type 8BUI to a grayscale JPEG:
    260260
    261 ST_AsJPEG(raster, "GRAYSCALE") - convert only band 1 with quality = 75
    262 ST_AsJPEG(raster, "GRAYSCALE", integer) - convert only band 1 with specified quality
    263 ST_AsJPEG(raster, integer, "GRAYSCALE") - allow specifying the band number to convert 
     261ST_AsJPEG(raster, "GRAYSCALE") - convert only band 1 with quality = 75[[BR]]
     262ST_AsJPEG(raster, "GRAYSCALE", integer) - convert only band 1 with specified quality[[BR]]
     263ST_AsJPEG(raster, integer, "GRAYSCALE") - allow specifying the band number to convert[[BR]]
    264264ST_AsJPEG(raster, integer, "GRAYSCALE", integer) - allow specifying the band number to convert and the quality
    265265
    266266Another series should allow converting 1 band raster of ANY pixel type to a grayscale JPEG. Pixel types different than 8BUI should be mapped according to specified min, max values and a mapping mode: "MaxMinValue" (default) or "MaxMinType".
    267267
    268 ST_AsJPEG(raster, "GRAYSCALE", min, max, text) - convert only band 1 with quality = 75
    269 ST_AsJPEG(raster, "GRAYSCALE", integer, min, max, text) - convert only band 1 with specified quality
    270 ST_AsJPEG(raster, integer, "GRAYSCALE", min, max, text) - allow specifying the band number to convert 
     268ST_AsJPEG(raster, "GRAYSCALE", min, max, text) - convert only band 1 with quality = 75[[BR]]
     269ST_AsJPEG(raster, "GRAYSCALE", integer, min, max, text) - convert only band 1 with specified quality[[BR]]
     270ST_AsJPEG(raster, integer, "GRAYSCALE", min, max, text) - allow specifying the band number to convert[[BR]]
    271271ST_AsJPEG(raster, integer, "GRAYSCALE", integer, min, max, text) - allow specifying the band number to convert and the quality
