NAME

librock_bits_from_ASCIIart - Store 1's and 0's into a bit vector for each non-space in a string.

#License - #Source code - #Example Use -

SYNOPSIS

#include <librock/parse.h>

void librock_bits_from_ASCIIart(char librock_PTR * pdest, /* Destination bit vector */
                    const char librock_PTR * psrc,
                    int cnt /* Number of characters at psrc */
                    );

DESCRIPTION

Create a bit vector based on the contents of a string. For every ASCII space (' '), store a 0, otherwise store a 1 into the bits of a char[], with the 0x80 position treated as the first bit.

The caller has to manage the storage at pdest and psrc.

Typical use would be to convert an ASCII-art (e.g. picture drawn with a text editor) into a bitmap.

#ifdef librock_TYPICAL_USE_bits_from_ASCIIart
    char dest;
    librock_bits_from_ASCIIart(&dest," A X XX ",8);
    printf("%02x\n",dest);
#endif
