API Scan
API Scan converts PDF documents into realistic scanned copies through API calls for automation and app integrations. PDF files are uploaded for remote processing, so this flow requires an internet connection. Customize color, noise, blur, borders and rotation, and use the API from any environment or programming language that can send HTTP requests.

interface ScanConfig {
rotate?: number // degrees to rotate the document
rotate_var?: number // degrees to rotate the document randomly
colorspace?: 'gray' | 'sRGB' // the colorspace of the output image
blur?: number // the amount of blur to apply to the image
noise?: number // the amount of noise to apply to the image
border?: boolean // whether to add a border to the image
brightness?: number // the brightness of the image. 1 is no change
contrast?: number // the contrast of the image. 1 is no change
resolution?: number // the resolution of the image in DPI
output_format?: 'image/png' | 'image/jpeg' // the format of the output image
}
