Save images on Linux

[JaapWijnen]

Is there any way to save images to png format on linux? That would be great :)

You can get raw pixels from an image and use third party png library to save it.
For example: https://github.com/kelvin13/png

If uncompressed 32 bit bmp format is also ok for your needs then you can check my simple pure swift BMP32Image class implementation: https://github.com/leszek-s/BMP32Image/blob/master/BMP32Image/BMP32Image.swift
