Nodejs plugin for Gifsicle
$ npm install @gumlet/gif-resize
import gifResize from '@gumlet/gif-resize'
import fs from 'node:fs';
const buf = fs.readFileSync("avocado.gif");
gifResize({
width: 200
})(buf).then(data => {
console.log("'data' contains processed GIF.");
});Returns a promise for a buffer.
Type: Object
Type: number
Resize GIF to given width in pixels. It maintains aspect ratio.
Type: number
Resize GIF to given height in pixels. It maintains aspect ratio.
Type: boolean
If this is set, and width and height both are provided, the GIF will be resized such that it exactly matches the dimensions provided. It won't match the aspect ratio.
Type: boolean
Default: false
Interlace gif for progressive rendering.
Type: number
Default: 0
This is process timeout in milliseconds. If set to positive number, it will throw timeout error after that many milliseconds.
Type: number
Default: 2
Select an optimization level between 1 and 3.
The optimization level determines how much optimization is done; higher levels take longer, but may have better results.
- Stores only the changed portion of each image.
- Also uses transparency to shrink the file further.
- Try several optimization methods (usually slower, sometimes better results)
Type: number
Reduce the number of distinct colors in each output GIF to num or less. Num must be between 2 and 256.
Type: string
Default: lanczos3
Set the method used to resize images. The sample method runs very quickly, but when shrinking images, it produces noisy results. The mix method is somewhat slower, but produces better-looking results. The default method is currently mix.
Gifsicle also supports more complex resamplers, including Catmull-Rom cubic resampling (catrom), the Mitchell-Netravali filter (mitchell), a 2-lobed Lanczos filter (lanczos2), and a 3-lobed Lanczos filter (lanczos3). These filters are slower still, but can give sharper, better results.
Type: number
Set the gamma correction to gamma, which can be a real number or ‘srgb’.
Type: array
Crop box in format [left, top, width, height].
Type: boolean
Flips GIF horizontally.
Type: boolean
Flips GIF vertically.
Type: number
Rotates GIF image. Valid values are 90, 180 and 270. All other values are silently ignored.
Type: Buffer
Buffer to optimize / resize.
