Mac 테스트용 이미지 생성

배경

파일 업로드 기능을 만들 때 등에 업로드용 테스트 이미지를 준비하는 것이 번거로웠습니다.
개발 환경이라면 그물에서 적당히 주워 온 이미지로 좋지만,
스테이징 등으로 테스트 할 때 취미 취향이 발레 발레가되어 버립니다. 이것은 좋지 않습니다.

목적

테스트용 이미지를 생성합니다.

소개

ImageMagick(이미지 매직)이라는 이미지 조작 라이브러리를 설치합니다.

$ brew install imagemagick

$ magick -version
Version: ImageMagick 7.0.7-33 Q16 x86_64 2018-05-17 https://www.imagemagick.org
Copyright: © 1999-2018 ImageMagick Studio LLC
License: https://www.imagemagick.org/script/license.php
Features: Cipher DPC HDRI Modules
Delegates (built-in): bzlib freetype jng jpeg ltdl lzma png tiff xml zlib

Homebrew가 없는 사람은 코코 에서 설치합시다.

예

파일은 명령을 실행한 위치에 이미지가 생성됩니다.

$ mkdir sample_image; cd sample_image

시도하는 경우 테스트 디렉토리를 만들어 둡시다!

단색 이미지 파일 만들기

$ magick -size 400x300 canvas:tomato bg_tomato.png

숫자가 포함된 이미지 만들기

$ magick -size 400x300 -background tomato -fill black -gravity center -pointsize 70 label:"000" bg_tomato_000.png

일련의 이미지 만들기

복사하면 10장의 연속 이미지가 3세트의 색 차이를 생성할 수 있습니다.

for i in `seq -f %03g 1 10`
do
  magick -size 400x300 -background tomato -fill black -gravity center -pointsize 100 label:$i bg_tomato_$i.png;
done

for i in `seq -f %03g 1 10`
do
  magick -size 800x600 -background teal -fill black -gravity center -pointsize 200 label:$i bg_teal_$i.png;
done

for i in `seq -f %03g 1 10`
do
  magick -size 1920x1080 -background skyblue -fill black -gravity center -pointsize 400 label:$i bg_skyblue_$i.png;
done

파일 매수가 많기 때문에 Dropbox에 올려 보았습니다.

테스트를 위해 URL 만 원하는 경우
