How to implement a 'good enough' image decompression ?

Hi !

I just connected an ili9163 tft display to my nodemcu. I would like to make a small client that fetchs images from a server and displays it. Did anybody implement a decompression software (gif, png or whatever) on the nodemcu ? Thanks !

Have a look here:
viewtopic.php?f=15&t=5807

He uses images to form the patterns and movement on a LED strip; perhaps you can grab some ideas there.

Thanks. But what I want is displaying a hi-res image via ESP8266 on a 128x128 or 320x240 color TFT screen. For this i'd prefer just sending an image through the internet & decompressing on the fly to the SPI TFT than having to send a bitmap...
