17 ps2epsi - generate conforming Encapsulated !PostScript
18 !!SYNOPSIS
19
20
21 __ps2epsi__ ''infile.ps'' [[ ''outfile.epsi'' ]
22 __(Unix)
23 ps2epsi__ ''infile.ps'' [[ ''outfile.epi'' ]
24 __(DOS)__
25 !!DESCRIPTION
26
27
28 __ps2epsi__ uses gs(1) to process a
29 __!PostScript__(tm) file and generate as output a new file
30 which conforms to Adobe's __Encapsulated !PostScript
31 Interchange__ (EPSI) format. EPSI is a special form of
32 encapsulated !PostScript (EPS) which adds to the beginning of
33 the file in the form of !PostScript comments a bitmapped
34 version of the final displayed page. Programs which
35 understand EPSI (usually word processors or DTP programs)
36 can use this bitmap to give a preview version on screen of
37 the !PostScript. The displayed quality is often not very good
38 (e.g., low resolution, no colours), but the final printed
39 version uses the real !PostScript, and thus has the normal
40 !PostScript quality.
41 !!USAGE
42
43
44 On Unix systems invoke __ps2epsi__ like
45 this:
46
47
48 __ps2epsi__ ''infile.ps'' [[ ''outfile.epsi''
49 ]
50
51
52 where
53
54
55 __ps2epsi__ ''infile.ps outfile.epi''
56
57
58 where
59 !!LIMITATIONS
60
61
62 Not every !PostScript file can be encapsulated successfully,
63 because there are restrictions on what !PostScript constructs
64 a correct encapsulated file may contain. __ps2epsi__ does
65 a little extra work to try to help encapsulation, and it
66 automatically calculates the bounding box required for all
67 encapsulated !PostScript files, so most of the time it does a
68 pretty good job. There are certain to be cases, however,
69 where the encapsulation does not work because of the content
70 of the original !PostScript file.
71 !!COMPATIBILITY
72
73
74 The __Framemaker__ DTP system is one application which
75 understands EPSI files, and __ps2epsi__ has been tested
76 on a number of !PostScript diagrams from a variety of
77 sources, using Framemaker 3.0 on a Sun workstation.
78 Framemaker on other platforms should be able to use these
79 files, although I have not been able to test
80 this.
