Examples

Image Processing

Using sharp for image processing.

// Source Formats [gif|jpg|png|tiff]
// Target Sizes: [256, 2048]
await sharp(blob)    
    .resize(size, size, {
        // use white background color with alpha transparency
        background: { r: 255, g: 255, b: 255, alpha: 1 }, 
        // resize to squared image best fitting width or height
        fit: 'inside',      
        // do not enlarge smaller images
        withoutEnlargement: true    
    })
    // The use of rotate implies the removal 
    // of the EXIF Orientation tag, if any
    .rotate()
    // Force output to a given format
    .toFormat('webp').toBuffer();
