- _t_o_c_h_u_n_k_y converts an SGI image file into SGI CHUNKY data format, for use
- by CHUNKY format printer drivers. However, the SGI CHUNKY chunky format
- has been superseded by Stream TIFF (STIFF). Conversions from SGI Image
- File format to STIFF are most efficiently accomplished by converting from
- SGI Image File format to PostScript using the program _s_g_i_2_p_s and then
- converting the PostScript to STIFF using the program _p_s_r_i_p.
-
- New development work should not use the SGI CHUNKY format.

- By default, tochunky assumes a zoomfactor of 1.0, and thus scales the
- image to be printed as large as possible without cropping.
-
- The ----PPPP option is followed by the full path to the printer's POD this
- option is given all settings except the zoomfactor are filled in from the
- config file, and need not be given unless the user wishes to override the
- settings in the POD database.
-
- The ----aaaa option specifies the printer's imageable area in dots in the
- horizontal (xsize) and vertical (ysize) directions. These values are
- normally derived from the POD database, which is kept up to date with the
- currently loaded paper size.
-
- The ----llll option specifies the printer resolution in dots per inch in the
- horizontal (xdpi) and vertical (ydpi) directions. These values are
- normally derived from the POD database, which is kept up to date with the
- current printer configuration.
-
- The ----dddd option specifies the printer data format, one of the following: KKKK
- (black only), CCCCMMMMYYYY (CMY only), or CCCCMMMMYYYYKKKK (CMYK data). The data format is
- normally derived from the POD database, which is kept up to date with the
- current printer configuration.
-
- If the ----zzzz option is given, then the image will be resized based on
- _z_o_o_m_f_a_c_t_o_r. _Z_o_o_m_f_a_c_t_o_r is a floating point value between 0.0 and 1.0,
- inclusive. The _z_o_o_m_f_a_c_t_o_r argument specifies a relative scaling: the
- scaling is proportional to the area of page which should be filled, and
- _z_o_o_m_f_a_c_t_o_r may be considered to be a percentage fill argument when its
- value is between 0.01 and 1.00. However, ----zzzz 0000....0000 is the exception to the
- rule: ----zzzz 0000....0000 indicates that _t_o_c_h_u_n_k_y should not zoom the image, but
- should print exactly one printer dot per image pixel.

- The resultant image is never cropped and is always centered on the page.

- 1. The ----PPPP option currently requires a full pathname to the printer's
- require just the printer name.
-
- 2. The ----zzzz option does not currently rotate the image if the image could
- be printed larger when printed 90 degrees rotated.
-
- 3. Since the ----pppp ppppppppiiii "pixels per inch" option is not implemented,
- setting the ----llll option will have no effect on the output image.

- This program has been obsoleted. All new development should be done with
- _s_g_i_2_p_s and _p_s_r_i_p and should use the STIFF file format. The _t_o_c_h_u_n_k_y
- program is provided for compatibility with previous releases of the
- Impressario product and may be removed from future releases.
