Interlaced image loads an early degraded version of the whole image as soon as possible and then progressively renders the image to clear state.

Non-interlaced image will load up in tiles showing clear image in each tile as it progresses to load in the image.

For .jpg the interlaced = progressive and not interlaced = baseline.

How to create a maven repository for your github project step by step

Clone your project in a separate folder

(note: replace ORGANIZATION and PROJECT)

git clone git clone git@github.com:ORGANIZATION/PROJECT.git my-repository

Copy and paste the swift code below into a playground to experiment.

This is a very close emulation of Functor and Monad typeclasses in swift. However, it is very fragile (i.e. easy to crash the compiler).

For example, instance methods of fmap will run fine, but attempting to use a globally defined fmap that acts on Functor types will cause a crash. Similarly for bind. Unfortunately this means we cannot define the nice infix operator versions of these functions.
