ftgrid - Man Page

simple glyph grid viewer

Synopsis

ftgrid [options] [pt] font ...

Description

ftgrid displays individual font glyphs magnified or reduced from a given size to fit the window. The glyph outlines are always shown as they appear before rasterization. The bitmap and the pixel grid are displayed when magnification permits it. It is possible to interactively change hinting and rendering options, thus visualizing the applied distortions to the outlines.

pt

The point size for the given resolution. By default at 72dpi, this directly gives the ppem value (pixels per EM).

font

The font file(s) to display. For Type 1 font files, ftgrid 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.

-a axis1,axis2,...

For Multiple Master, GX, or OpenType variation fonts, specify design coordinates for each axis at start-up. This option implies option -n. Ignored for all other font formats.

-n

Don't display named instances of variation fonts.

-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.
