JPEG to PNM features

The NodeJS package for converting JPEG images to PNM files.

ConvertAPI Node.js library install

ConvertAPI provides a Node.js library that allows you to perform a JPEG to PNM conversion with just a few lines of code. First, install our convertapi library from npm:

NPM package >
npm install convertapi --save

Authenticate your Node.js library

You can obtain your secret key by signing up for a free account. Once you sign up, you'll receive 250 free conversions instantly! Grab your authentication secret from the account dashboard, and authenticate the ConvertAPI Node.js library like this:

// get your secret key here: https://www.convertapi.com/a/auth
var convertapi = require('convertapi')('secret_or_token');
Or using ES modules:
import ConvertAPI from 'convertapi';
const convertapi = new ConvertAPI('secret_or_token');

Conversion parameters

ImageResolution Integer

Set output image resolution in dpi.

ScaleImage Bool

Scale the output image. If ScaleImage is False output document will be stripped to ImageHeight / ImageWidth, if ScalePage is True output document will be scaled to ImageHeight / ImageWidth.

ScaleProportions Bool

Constrain proportions when scaling the output image.

ScaleIfLarger Bool

Scaling only if the input image is larger than the output.

ImageHeight Integer

Image height in pixels.

ImageWidth Integer

Image width in pixels.

ImageInterpolation Bool

Specifies whether the image parser should use image interpolation. Enabling image interpolation will result in higher quality for scaled images at the expense of speed.

TransparentColor String

Add alpha channel to image, setting pixels matching color to transparent. Values accepted are RGBA, CMYK hex string, color name or RGB format like this 255,255,255 (RED=255, GREEN=255, BLUE=255) or 255,255,255,150 with alpha chanel.
