使用 ImageMagick Composite 合成功能

使用合成程序將一個圖像重疊在另一個圖像上。

有關如何構造合成命令的建議,請參閱命令行處理,或參見下列的命令範例用法。

/usr/local/ImageMagick/bin/magick composite -help

範例用法

在此列出一些合成命令的範例,以說明其有用性和易用性。


首先,讓我們在玫瑰上疊加一個笑臉:

/usr/local/ImageMagick/bin/magick composite -gravity center smile.gif rose.jpg rose-over.png

或者,可以使用 Atop 創建三維效果:

/usr/local/ImageMagick/bin/magick convert -size 70x70 canvas:none -fill red -draw 'circle 35,35 10,30' red-circle.png
/usr/local/ImageMagick/bin/magick convert -size 70x70 canvas:none -draw 'circle 35,35 35,20' -negate -channel A -gaussian-blur 0x8 white-highlight.png
/usr/local/ImageMagick/bin/magick composite -compose Atop -geometry +0+0 white-highlight.png red-circle.png red-ball.png

可以在 Examples of ImageMagick Usage 的範例中找到使用合成的其他範例。
