NAME

       ftview - simple glyph viewer

SYNOPSIS

       ftview [options] [pt] font ...

DESCRIPTION

       ftview  displays  all  glyphs  of  a  font,  allowing changes of various rendering and hinting parameters
       interactively.

       pt     The point size for the given resolution.  If resolution is 72dpi, this  directly  gives  the  ppem
              value (pixels per EM).

       font   The font file(s) to display.  For Type 1 font files, ftview also tries to attach the corresponding
              metrics file (with extension `.afm' or `.pfm').

       This program is part of the FreeType demos package.

OPTIONS

       -d WxH[xD]
              Set  the  window  width  to  W px, the height to H px, and optionally the depth to D bpp (default:
              640x480x24).

       -r r   Use resolution r dpi (default: 72dpi).

       -f index
              Specify first index to display (default: 0).

       -e enc Specify encoding tag (default: no encoding).  Common values: unic (Unicode), symb  (symbol),  ADOB
              (Adobe standard), ADBC (Adobe custom), or a numeric charmap index.

       -m text
              Use text for rendering.

       -l mode
              Set  start-up  rendering  mode  (0  <=  mode <= 6).  This corresponds to the keystrokes 'A' to 'G'
              within the program.

       -L W1,W2,W3,W4,W5
              If there are five arguments,  set  LCD  filter  weights  (as  specified  in  function  FT_Library_
              SetLcdFilterWeights).

       -L G1,G2,G3,G4,G5,G6
              If  there  are  six  arguments,  set  the  subpixel geometry (as specified in function FT_Library_
              SetLcdGeometry) depending on the implemented subpixel rendering method.

       -p     Preload file in memory to simulate memory-mapping.

       -k keys
              Emulate sequence of keystrokes upon start-up.  If the keystrokes contain 'q', the program operates
              in batch mode.  Function keys Fx are mapped to character codes 0xFx; as an example, -k $'\xF3q' is
              function key 'F3' followed by character 'q'.

       -v     Show version.
