15
17 grap2graph reads a grap(1) program from the standard input and writes
18 an image file, by default in Portable Network Graphics (PNG) format, to
19 the standard output.
20
21 The input GRAP code should not be wrapped with the .G1 and .G2 macros
22 that normally guard it within groff(1) documents.
23
24 Arguments not recognized by grap2graph are passed to the ImageMagick or
25 GraphicsMagick program convert(1). By specifying these, you can give
26 your image a border, set the image's pixel density, or perform other
27 useful transformations.
28
29 The output image is clipped using convert's -trim option to the small‐
30 est possible bounding box that contains all the black pixels.
31
33 -format output-format
34 Write the image in output-format, which must be understood by
35 convert; the default is PNG.
36
37 --help Display a usage message and exit.
38
39 -unsafe
40 Run groff in unsafe mode, enabling the PIC command sh to execute
41 arbitrary Unix shell commands. The groff default is to forbid
42 this.
43
44 -v
45 --version
46 Display version information and exit.

50 TMPDIR
51 TMP
52 TEMP These environment variables are searched in the given order to
53 determine the directory where temporary files will be created.
54 If none are set, /tmp is used.

57 grap2graph was written by Eric S. Raymond ⟨esr@thyrsus.com⟩, based on a
58 recipe for pic2graph(1), by W. Richard Stevens.
