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
       -L Rx,Ry,Gx,Gy,Bx,By
              Depending on the implemented subpixel rendering method and the
              number of provided arguments, set either five LCD filter weights
              or six subpixel coordinates (as specified in functions FT_
              Library_SetLcdFilterWeights or FT_Library_SetLcdGeometry
              respectively).

       -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'.

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

       -v     Show version.
