[Question]
  [
The [PBM (Portable BitMap) format](http://en.wikipedia.org/wiki/Netpbm_format#PBM_example) is a very simple ASCII black and white bitmap format.
Here's an example for the letter 'J' (copy-pasted from the wikipedia link):
```
P1
# This is an example bitmap of the letter "J"
6 10
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
1 0 0 0 1 0
0 1 1 1 0 0
0 0 0 0 0 0
0 0 0 0 0 0
```
It's time we build a small tool to generate files in this nifty little format!
Your **goal** is to write the shortest program (in any language) that conforms to the following rules:
1. Your program takes one string from stdin (for example `CODEGOLF.STACKEXCHANGE.COM!`)
2. It generates a PBM file with a bitmapped (readable) representation of the string.
3. Each character is constructed as a 8x8 grid.
4. You must support the characters [A-Z] (all uppercase), space, a point ('.') and an exclamation mark ('!').
5. No external libraries allowed (certainly no PBM related ones)!
6. The used character set must not simply be external to your program. Part of the challenge is storing the characters efficiently...
Testing for validness of the PBM format can be done with the GIMP (or others). Do show off sample input and output!
**The shortest solution will be awarded the answer points on 2012-01-31.**
Have fun golfing!

## Perl, 164 bytes, no zlib/gzip compression
After sleeping on the problem, I managed to figure out a much shorter solution than my first one. The trick is to take advantage of a minor loophole in the rules: the characters need to fit in 8 by 8 pixels each, but nothing says they have to *fill* all that space. So I drew my own 4 by 5 pixel font, allowing me to pack two characters into 5 bytes.
The output looks like this:
!["HELLO WORLD!"](https://i.stack.imgur.com/RqiN6.png) (scaled x 4)
    !["OH! A QUICK BROWN FOX JUMPS OVER THE LAZY DOG."](https://i.stack.imgur.com/iCvMZ.png) (original size)
Before giving the actual code with the embedded font data, let me show a de-golfed version:
```
y/A-Z!./\0-\033/ for @a = <> =~ /./g;
say "P4 " . 8*@a . " 8";
for $p (qw'PACKED FONT DATA') {
    print chr vec $p, ord, 4 for @a;
}
```
In the actual code, the `PACKED FONT DATA` is replaced by a binary string consisting of eight whitespace-delimited rows (four 14-byte rows and one 13-byte one, plus three single null bytes for the blank rows). I deliberately designed my font so that the packed data contains no whitespace, single quotes or backslashes, so that it could be encoded in `qw'...'`.
Since the packed font string contains unprintable characters, I've provided the actual script as a hex dump. Use `xxd -r` to turn it back into executable Perl code:
```
0000000: 792f 412d 5a21 2e2f 002d 1b2f 666f 7240  y/A-Z!./.-./for@

00000a0: 7240 617d                                r@a}
```
**Here's how it works:**
* The first line (in the de-golfed version) reads a single line of input, splits it into an array of characters (conveniently omitting any trailing newlines) and maps the letters `A` to `Z` and the characters `!` and `.` to the character codes 0 to 28, which normally correspond to unprintable control characters in ASCII / Unicode. (A minor side effect of this is that any tabs in the input get printed as `J`s.) The space character is left unmapped, since the output loop turns any codes above 28 into blanks anyway.
* The second line just prints the PBM header. It uses the Perl 5.10 `say` feature, so you need to run this script with `perl -M5.010` for it to work.
* The output loop takes a whitespace-delimited list of packed image rows and assigns each of them into `$p` in turn. (I designed the font so that the packed data wouldn't contain any whitespace or `'` characters.) It then loops over the input characters in `@a`, using Perl's `vec` command to extract the 4-bit nibble corresponding to the mapped character code from the image row, pads it to an 8-bit byte and prints it.

The decompressed Perl code consists of the following preamble:
```

```
followed by eight repetitions of the following code:
```
;$_=$t;y(A-Z.! )'BITMAP DATA HERE';print
```
with `BITMAP DATA HERE` replaced with 29 bytes encoding one row of the font.

## GolfScript, 133 bytes
This is based on [my 164-byte Perl solution](https://codegolf.stackexchange.com/a/4682/3191) and uses the same nibble-packed 4 by 5 pixel font. Again, I'll give the readable version first:
```
{91,65>"!. "+?}%:s"P4"\,8*8'FONT DATA HERE'{16base}%[3]/{:p;{[p=0]0=}s%}%]n*
```
Here, `FONT DATA HERE` stands for 71 bytes of binary packed font data. The encoding is slightly different than in the Perl version: instead of splitting the packed string on whitespace, I expand it first and then split it on the nibble `3` (chosen because it just happens not to occur anywhere in the font).
Since the font data in the actual script contains unprintable characters, I give it as a hex dump below. Use `xxd -r` to turn the hex dump back into executable GolfScript code:
```

```
Unlike the Perl script, this code prints any characters outside the set `A`–`Z`, `!`, `.`, `space` as funny-looking little squiggles. Replacing the squiggles with blanks would cost 2 extra chars; removing them entirely would cost 4.
This is my first GolfScript program ever, so I wouldn't be surprised if there's some room left for optimization. Here's how it works:
* `{91,65>"!. "+?}%:s` maps the valid input characters (`A`–`Z`, `!`, `.`, `space`) to the numbers 0 – 28 and assigns the result to `s`. Any characters outside the valid set get mapped to -1, which is what produces the squiggles when printed.
* `"P4"\,8*8` pushes the values "P4", 8 times the length of the input, and 8 onto the stack. When printed at the end, these will form the PBM header.
* `{16base}%[3]/` takes the preceding string of font data, splits each byte of it into two nibbles, and splits the result into blocks delimited by the value `3`. `{:p;{[p=0]0=}s%}%` then loops over these blocks, first assigning each block to the variable `p` and then looping over the remapped input string `s`, replacing each character with the value at the corresponding offset in `p`. The funny-looking construct `[p=0]0=` does the same as `p=`, except that it returns 0 for any offsets past the end of `p`; I don't really like it, but I haven't been able to figure out any shorter way to handle that.
* Finally, `]n*` takes everything on the stack (the three header values and the image data array) and joins them together with newlines for printing.

### Explanation
* `od` is the standard "octal dump" utility program. The `-tu1` option tells it to produce a decimal dump of individual bytes instead (a sufficient workaround for bash's lack of asc(), ord(), .charCodeAt(), etc.)
* `P4` is the magic number for a binary format PBM file, which packs eight pixels into each byte (versus `P1` for the ASCII format PBM file). You will see how this proves useful.
* Per row of final output, the program pulls an eight-pixel byte (corresponding to the ASCII code and line number) from the gzip-compressed data section at the end using `dd`. (`tail -2 $0` extracts the script's last two lines; the compressed data includes one 0x0a linefeed byte.) It so happens that eight pixels is the width of a single character. The null bytes that fill the gaps between supported characters are easily compressible because they are all the same.
* All this is written to a file named "8". Because there are exactly eight rows (and also eight pixels per byte), the number of bytes is the width of the output in pixels. The output's height is also included in that `wc -c` prints the input filename "8" after its byte count.
* Now that the header is complete, the image data is printed. Bash only notices that the last two lines are not valid commands (the last one actually invalid UTF-8) after it has executed everything coming before.
* I used KZIP only to compress the data section, [as Ilmari Karonen did](https://codegolf.stackexchange.com/a/4196/163) for an *entire submission* to the 12 Days of Christmas challenge. As described there, it is essentially necessary to use a hex editor to replace the ZIP header format with a gzip header. Including the CRC-32 and file size from the original ZIP header seems to be unnecessary.

It takes 93 bytes of code when using goruby:
```
ps"P1\n#{(s=gt).sz*8} 8",8.mp{|i|s.y.fl{|o|8.mp{|j|'DATA'.ua('Q<*')[o>64?o-63:o/46][i*8+j]}}*' '}
```
Using ZLib trim the data size to 142 bytes instead of 224, but adds 43 bytes in the code, so 307 bytes:
```
#coding:binary
require'zlib';z=0..7;puts"P1\n#{(s=gets).size*8} 8",z.map{|i|s.bytes.flat_map{|o|z.map{|j|Zlib.inflate("DATA").unpack('Q<*')[o>64?o-63:o/46][i*8+j]}}*' '}
```
Which gives a total of 268 when using goruby:
```
#coding:binary
rq'zlib';ps"P1\n#{(s=gt).sz*8} 8",8.mp{|i|s.y.fl{|o|8.mp{|j|Zlib.if("DATA").ua('Q<*')[o>64?o-63:o/46][i*8+j]}}*' '}
```

### Java 862 826:
Here is a different approach. I think 'awt' does not count as external lib.
```
import java.awt.*;
class B extends Frame{String s="ABCDEFGHIJKLMNOPQRSTUVWXYZ .!";int l=29;static Robot r;int[][][]m=new int[l][8][8];
public void paint(Graphics g){for(int y=0;y<8;++y){int py=(y<3)?y:y+1;for(int a=0;a<l;++a)
for(int x=0;x<8;++x)
m[a][x][y]=(r.getPixelColor(8*a+x+17+x/4,py+81)).getRGB()<-1?1:0;}
System.out.println("P1\n"+(getTitle().length()*8)+" 8");
for(int y=0;y<8;++y){for(char c:getTitle().toCharArray()){int a=s.indexOf(c);
for(int x=0;x<8;++x)System.out.print(m[a][x][y]);}
System.out.println();}
System.exit(0);}
public B(String p){super(p);
setBackground(Color.WHITE);
setSize(400,60);
Label l=new Label(s);
l.setFont(new Font("Monospaced",Font.PLAIN,13));
add(l);
setLocation(9,49);    
setVisible(true);}    
public static void main(String a[])throws Exception{r=new Robot();    
new B(a[0]);}}
```
And ungolfed:

        setVisible (true);
    }
       
    public static void main (String args[]) throws Exception
    {
        new PBM (args[0]);
    }    
}
```
Robot is the somehow curious way of Java to call getPixel. I create a Label with the alphabet, and measure where a pixel is for each letter.
In the paint method, `int py = (y < 3) ? y : y +1;` and `(8*a+x+17+x/4, py+81)` is the complicated way, to adjust the position in the font. Huuuh! else it would need 9 lines, and every 4th letter, there is an additional pixel horizontally. Trial and error brought me to this solution.
Then the header of the PBM is written, and each line of the message. The message is passed as title of the frame.
That's it. Not the shortest code, but no manual font painting was necessary.
Maybe it could be shorter in BeanShell or Scala.
And now - how does it look like?

Not that the number of chars is the number of chars from the Perl solution shuffled.
(golfed a little bit more. Made Robot static, which avoids one Exception declaration.)

# C++ TOO LARGE TO WIN
I wrote a full featured PPM drawing program in C++, with my own bitmapped font. Even stripping out all non necessary functions it's still huge compared to the answers here because of the definition for the font.
