Fuze Code Screenshot Decoder

This tool will decode pictures where each character as been encoded in the pixel data. It decodes pictures where each characters data is represented with 8 pixels, one pixel per bit to form a byte / character. White pixels equals bit 1 and black pixels equals 0. It then checks for R < 128, G < 128, B < 128 to decode the pixels back.

needed code on fuze 4 nintendo switch

The code below is needed to encode the pictures and you need to take a screenshot of the screen.

//fuze Code exporter to image created by willems davy aka joyrider3774
//
//use 1280x720 when using switches build in screenshotting system
//when using hdmi capture card can use 1920x1080 but make sure your viewer app
//can screenshot at this resolution in best quality. I personally use windows 10 camera app
//
//copy / paste your program's code to the test variable below.
//make sure to escape strings by replacing a single double quote ["] with [" + chr(34) + "] 
//for every occurance of it or your multiline string defintion of your code will be wrong and 
//fuze does not give an error on it but it will not export full code then. Also if you have
//very very long code and fuze gives an error on the string constant off your code
//split up the string in multiple string constants and concatenate them when calling the encode
//function 
//
