 // ImGui - binary_to_compressed_c.cpp
-// Helper tool to turn a file into a C array.
-// The data is first compressed with stb_compress() to reduce source code size.
-// Then encoded in Base85 to fit in a string so we can fit roughly 4 bytes of compressed data into 5 bytes of source code (suggested by @mmalex)
-// (If we used 32-bits constants it would require take 11 bytes of source code to encode 4 bytes.)
-// Useful if you want to embed fonts into your code.

 // Note that even with compression, the output array is likely to be bigger than the binary file..
