在下文中一共展示了concurrency函數的2個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的TypeScript代碼示例。
示例1:
.resize(200, 200)
.max()
.toFormat('jpeg')
.toBuffer()
.then((outputBuffer: Buffer) => {
// outputBuffer contains JPEG image data no wider than 200 pixels and no higher
// than 200 pixels regardless of the inputBuffer image dimensions
});
const stats = sharp.cache();
sharp.cache({ items: 200 });
sharp.cache({ files: 0 });
sharp.cache(false);
const threads = sharp.concurrency(); // 4
sharp.concurrency(2); // 2
sharp.concurrency(0); // 4
const counters = sharp.counters(); // { queue: 2, process: 4 }
let simd: boolean = sharp.simd();
// simd is `true` if SIMD is currently enabled
simd = sharp.simd(true);
// attempts to enable the use of SIMD, returning true if available
const vipsVersion: string = sharp.versions.vips;
if (sharp.versions.cairo) {
const cairoVersion: string = sharp.versions.cairo;示例2: require
const sharp = require("sharp")
sharp.concurrency(2)
const sizes: { [key: string]: { height: number, width: number} } = {

tiny: { height: 30, width: 30 },
}
/**
* Create Image Output takes an image path, and returns an array of processed images
* - large: full optimized image
* - medium: Suitable for showing as article or gallery image
* - small: Suitable for thumbnail, icon, etc
* - tiny: Suitable only for progressive image loader
* - svg-prog (SOONtm): SVG progressive image loader
