如何使用ImageMagick将GIF放置在另一个GIF上，其中两个GIF的大小均不同 [英] How to place a GIF on another GIF with ImageMagick, where both GIFs are of different sizes

问题描述

我有两个大小不同的GIF.我希望能够将一个动画GIF放置在特定位置的静态背景GIF上，同时在结果中添加文本.我是ImageMagick世界的新手，请帮助.

I have two GIFs of different sizes. I want to be able to place one animated GIF onto a static background GIF at a specific location and at the same time add text to the result. I am new to ImageMagick world, please help.

当狗贴在单独的GIF中时，我试图获得以下结果.

I am trying to achieve the following result where dog sticker is in a separate GIF.

推荐答案

也许这正是您想要的. Unix语法中的Imagemagick命令行代码:

Perhaps this is more what you want. Imagemagick command line code in unix syntax:

背景动画有3帧，前景动画有11帧.因此，我将背景重复4次并删除最后一帧，因此背景总共有11帧.我合并动画，并使用-annotate将文本添加到每个帧.然后，我使用-layers Composite将前景动画叠加到背景上.

The background animation has 3 frames and foreground one has 11 frames. So I repeat the background 4 times and remove the last frame so there is a total of 11 frames for the background. I coalesce the animation and add text to each frame using -annotate. Then I use -layers composite to overlay the foreground animation onto the background.

背景:

前景:

convert -delay 20 \
\( glitter_blue_tiled.gif glitter_blue_tiled.gif \
glitter_blue_tiled.gif glitter_blue_tiled.gif \
-coalesce \
+delete \
-font arial -pointsize 28 -fill black -gravity north \
-annotate +0+20 "TESTING" \) \
null: \
\( coalesced_k.gif -coalesce \) \
-gravity south -geometry +0+20 \
-compose over \
-layers composite \
-layers optimize \
-loop 0 \
