NAME

       gimpprint-imagetypes - Gimp-Print image types

DESCRIPTION

       Gimp-Print includes several image types which can be used to optimise the dither, depending on the type of image you wish to print.

IMAGE TYPE

       Possible values are:

       Value   Description
       -------------------------------------------------
       1       Line art (color or gray scale)
       2       Primarily  solid colors or smooth gradi-
	       ents (color or gray scale)
       3       Continuous-tone	photographs  (color  or
	       gray scale)

       Option  0 is the fastest.  It generates strong, but not particularly accurate, colors.  There may be some fairly sharp color transitions in
       this mode.

       Option 1 generates more accurate colors, but is slower.

       Option 2 generates the most accurate colors, but is considerably slower.

       Note that any of the modes may be used with either color or black & white output.  If black and white output is requested, but a color mode
       used,  composite  color will be printed.  This generally offers smoother tone, but less purity of gray or black, than pure black ink.  Fur-
       thermore, it is possible to tune the color of the gray (to achieve warmer or cooler effects) using the color controls in this fashion.
