Question

我已经制定了一个简单的方案,利用不和,我想把仍然的形象与含有im化框架的形象结合起来,那么,机器人将传播一个形象中的形象和仍然形象的背景。

const Discord = require( discord.js );
const sharp = require( sharp );
const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] });

client.on( messageCreate , async message => {
    if (message.content ===  !merge ) {
        const background = await sharp( logo.png ).resize(288, 288);
        const overlay = await sharp( banana.gif ).resize(288, 288);

        const result = await background.composite([{ input: await overlay.toBuffer(), gravity:  center  }]).toBuffer();

        message.channel.send({ files: [result] });
    }
});

client.login( your-token );

But the result was not successful, it sends a static image without the animated frames in GIF format.
I tried to search for a package, but did not find anything.

我们希望有人能够帮助我们这样做,感谢你。

In order to create an animated image you must tell sharp to animate the result of the composite.

According to the documentation the default behavior of composite is to have a default value of animated = false. So what you want to do is tell it which images are animated.

Change this line
const result = await background.composite([{ input: await overlay.toBuffer(), gravity: center }]).toBuffer();
To
const result = await background.composite([{ input: await overlay.toBuffer(), gravity: center , animated: true }]).toBuffer();
Notice the animated: true declaration for the overlay input.

Hopefully this helps.
