Description =========== "shapng" is a tool to convert a sha256-sum, gained from a string or file, into a 16x16 png-image. This image can be read visualy by mobile phones or other robots. How does it work ---------------- First, a sha256-sum is generated from the input. Then, this sum is converted into a array of 256 bits and converted more into a 16x16 bit-box. The first bit is assigned to the top-left and the last to the right-bottom. It it READ horizontaly, from left to right and line by line. Requirements ============ - AmigaOS 4.x Installation ============ Copy the executable to C: Usage ===== "shapng" does only work from a shell. Arguments --------- NAME/A,TO,S=SIZE/N,FG=FORGROUND/N,BG=BACKGROUND/N,PS=PRINTSUM/S NAME/A - Filename or string for input. If the string is a filename, it is handled as file, else as string. (Mandatory) TO - Output file. If blank, "PROGDIR:<NAME/A>.sha.png" is created. (Optional) S=SIZE/N - Size of the blocks in gfx. Defaults to 4. (Optional) FG=FORGROUND/N - Forground color as hex-number in the format 0x<RR><GG><BB>. Defaults to 0x000000. (Optional) BG=BACKGROUND/N - Background color as hex-number in the format 0x<RR><GG><BB>. Defaults to 0xffffff. (Optional) PS=PRINTSUM/S - Also print the sha-sum to stdout. Defaults to false. (Optional) Examples -------- shapng "Hello World" ram:icon.png" - creates "ram:icon.png" from the string. shapng shapng.readme - creates "shapng.readme.sha.png" in PROGDIR. shapng shapng.readme SIZE 10 - increase gfx-blocksize to 10.
