NAME

6       ftview - simple glyph viewer
7

SYNOPSIS

9       ftview [options] [pt] font ...
10

DESCRIPTION

12       ftview  displays all glyphs of a font, allowing changes of various ren‐
13       dering and hinting parameters interactively.
14
15       pt     The point size for  the  given  resolution.   If  resolution  is
16              72dpi, this directly gives the ppem value (pixels per EM).
17
18       font   The font file(s) to display.  For Type 1 font files, ftview also
19              tries to attach the corresponding metrics file  (with  extension
20              `.afm' or `.pfm').
21
22       This program is part of the FreeType demos package.

OPTIONS

25       -d WxH[xD]
26              Set the window width to W px, the height to H px, and optionally
27              the depth to D bpp (default: 640x480x24).
28
29       -r r   Use resolution r dpi (default: 72dpi).
30
31       -f index
32              Specify first index to display (default: 0).
33
34       -e enc Specify encoding tag (default:  no  encoding).   Common  values:
35              unic  (Unicode),  symb  (symbol),  ADOB  (Adobe  standard), ADBC
36              (Adobe custom), or a numeric charmap index.
37
38       -m text
39              Use text for rendering.
40
41       -l mode
42              Set start-up rendering mode (0 <= mode <= 6).  This  corresponds
43              to the keystrokes 'A' to 'G' within the program.
44
45       -L W1,W2,W3,W4,W5
46              If  there  are five arguments, set LCD filter weights (as speci‐
47              fied in function FT_Library_SetLcdFilterWeights).
48
49       -L G1,G2,G3,G4,G5,G6
50              If there are six arguments, set the subpixel geometry (as speci‐
51              fied in function FT_Library_SetLcdGeometry) depending on the im‐
52              plemented subpixel rendering method.
53
54       -p     Preload file in memory to simulate memory-mapping.
55
56       -k keys
57              Emulate sequence of keystrokes upon start-up.  If the keystrokes
58              contain  'q', the program operates in batch mode.  Function keys
59              Fx  are  mapped  to  character  codes  0xFx;  as   an   example,
60              -k $'\xF3q' is function key 'F3' followed by character 'q'.
61
62       -v     Show version.
