사용자 정의 텍스트를 전체 화면 크기로 표시하는 애플리케이션의 이름은 무엇입니까?

몇 년 전에 나는 매우 편리한 응용 프로그램을 보았습니다. 명령은 전체 화면에 맞게 확대된 첫 번째 인수를 표시합니다. 예를 들어...

thiscommand AA

...그리고 두 개의 매우 큰 A가 전체 화면을 채우는 것을 볼 수 있습니다. 또는...

thiscommand "[email protected]"

...화면 너비와 동일한 너비로 이메일 주소를 표시합니다. 키를 한 번만 누르면 q끌 수 있습니다 (아마도 ). 사람들과 대화하거나 프리젠테이션을 할 때 짧은 텍스트, 단 몇 단어만 빠르게 표시해야 할 때 일반적으로 이 애플리케이션이 매우 유용하다고 생각합니다.

내 문제는 이 프로그램의 이름을 잊어버렸고 Google을 통해 찾으려고 매우 열심히 노력했지만 성공하지 못했다는 것입니다. 아는 사람 있나요?

배너; 내 시스템에서는 printerbanner맨페이지로 연결하려고 했는데 온라인이나 하드 드라이브에서 찾을 수 없습니다.

printerbanner매우 긴 문자열을 허용하기 위해 텍스트를 가로 방향으로 인쇄하지만 정상적으로 인쇄하는 옵션이 없는 것 같습니다.

모든 PostScript 뷰어에서 올바르게 표시되어야 합니다. 예를 들어 okularImageMagick/GraphicsMagick 유틸리티를 사용하여 표시하려면 display:

display -geometry 1024x768 -density 72 demo.ps

렌더링된 이미지의 품질을 향상시키려면 밀도 매개변수(예: 300 시도)를 높이십시오. display옵션을 사용하여 배경 창에 이미지를 표시할 수 있습니다 -backdrop. Ctrl-Q를 사용하여 창을 닫습니다.

(Unix & Linux)데모.ps의 텍스트 문자열은 수정할 수 있습니다 . 프로그램은 사용할 올바른 글꼴 크기를 자동으로 계산합니다.

Demo.ps 파일을 PDF로 변환하려면할 수 있다ImageMagick/GraphicsMagick convert유틸리티 사용

convert -page 1024x768 demo.ps demo.pdf

하지만 아마도 사용하는 것이 더 빠를 것입니다(그리고 출력이 더 컴팩트합니다).

#Generate a Postscript file that prints a line of text that fills the screen

bold(){ echo -e "\x1b[1m$*\x1b[0m"; }

help1()
{
    cat << EOF

Display a single line of text at the largest scale that fits within the screen (or requested size).

This script generates a Postscript program which performs the scaling calculation and sets the text
in the requested font. The Postscript file is then displayed using the ImageMagick / GraphicsMagick
utility $(bold display), which should be installed on most modern Linux systems.

$(bold Usage:)
$(basename "$0") [-h] [-bden] [-f fontname] [-g geometry] [-m margin] [-q quality] [-s savename.ps] [-t text] text...

Options may be given in any order.

$(bold Options:)
    -h : print this Help & exit. -hh prints extra help.
    -b : disable the use of a Backdrop window.
    -d : disable Display of the text.
    -e : disable backslash Escaping of the text string.
    -n : use Normal encoding instead of the default ISO Latin1 encoding.

    -f : the name of the Font, either a PostScript or system font. Default = 'Times-Roman'
    -g : Geometry, in WIDTHxHEIGHT format. If not given, the current default screen size is used.
    -m : left & right (&/or top & bottom) Margin (in pixels) around text bounding box. Default = 8
    -q : rendering Quality. Default quality = 1.0
    -s : Save PostScript. Use $(bold '-s -') to save to stdout.
    -t : the Text to display.
EOF
}

help2()
{
    cat << EOF

By default, $(bold display) shows the text in a backdrop window. You can use Control-Q to close
$(bold display) windows, or use a right mouse click to bring up a context menu.
See the $(bold display) documentation for further information.

$(bold Text)
Multiple -t text options may be given, they will be joined together with an intervening space.
Any arguments specified after the options will be added to the text, so there is no need to quote
the text string, but it will be necessary to use -- to terminate the options section if any of the
subsequent text words begin with a - dash.

$(bold Font)
The font name must conform to the PostScript naming convention,
in particular, it cannot contain spaces. So if a font you'd like to use does
have spaces in its name try dropping the spaces or replacing them with a - dash.

$(bold Quality)
The quality setting is essentially an internal scaling factor for the $(bold display) utility.
The default quality setting of 1.0 is reasonably fast, but the outline of the text may look
jagged, especially with short text strings. Lower quality settings may be a little faster,
but the outline can look quite blurry; settings lower than 0.2 are virtually unusable.
High quality settings take longer to render but can look quite good; 2.0 should be
adequate for most purposes, 4.0 takes quite a while to render but looks great; higher settings
take even longer but the improved quality is unlikely to be noticeable.

$(bold Save)
Normally, the PostScript program generated by this script is simply piped into the $(bold display)
utility, but you may save it to a file. This allows you to show (or print) the rendered text
with other PostScript utilities. If you wish, you can edit the PostScript program by hand,
to change the font, text, page size, etc, as the text scaling calculations are performed within the
PostScript program.

To display the file "savename.ps" with okular:
okular savename.ps

To display it with GhostScript in a 1024x768 window:
gs -sDEVICE=x11alpha -dBATCH -g1024x768 -r72 savename.ps

$(bold Escape)
By default, this program prefixes all backslashes $(bold '\\') and parentheses $(bold '()') in
the text string with a backslash to convert the string to PostScript form.
You can disable this behaviour using the $(bold '-e') option.

The PostScript language uses backslash as an escape character, and it uses parentheses instead
of quotes to enclose strings; any unmatched parentheses in a string must be backslash escaped
(but matched parentheses are ok). PostScript understands various other standard C escape sequences,
including character codes represented by backslashed octal sequences, but it does not understand
hexadecimal escape sequences.
Please see a PostScript reference for further information.

$(bold Encoding)
By default, this program uses the ISO Latin 1 encoding for text, but you can use PostScript's
Normal encoding vector by specifying the $(bold '-n') option. This program does not support
Unicode text.
