b2c / bytes to colors

Raw byte data to image converter/visualizer. Image shows a Windows executable ^^^

Made with raylib.

What it does

It takes raw byte data through standard input, whether typed in manually or piped in, assigns each byte to a red, green or blue channel (alpha channel is permanently at 255), those become pixels in an array which becomes an image written to the disk.

How to use it

stdin.

Flags:

-v --verbose : for some printfs

-d --display --draw : for displaying the image in a window instead of saving it to a file

-w --width : change the preffered width of the window (only has any effect if also doing -d/--display/--draw)

-r --reverse : Take an image as input, and spit out a file as output. The reverse of the program's default function.

To do

• Add option to memcmp 2 files and show the differences between them (if any) as an rgb8 image.
• [DONE] Add option to reverse the effect of the program by taking in an image as the input and outputting a file.

Known issues

• [FIXED] If started with -d, the program will not listen to kill signals, and must be killed with ^C.
• [FIXED] If started with -d, and processing a very big file, funky visual bugs happen.

Building it

Build file exists only for GNU/Linux, and the code may use libraries unavailable on Windows. Needs Raylib <3
