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 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
============
- MorphOS 1.x
INSTALLATION

---------
NAME/A,TO,S=SIZE/N,FG=FORGROUND/N,BG=BACKGROUND/N,PS=PRINTSUM/S
NAME/A - Filename or string for input.

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.

------------
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.
