lispmtopgm - convert a Lisp Machine bitmap file into pgm format |

!!DESCRIPTION |

|

|
| |
|
21 |
Reads a Lisp Machine bitmap as input. Produces a portable |
| |
|
22 |
graymap as output. |
| |
|
23 |

| |
|

|
| |
|
25 |
This is the file format written by the |
| |
|
26 |
tv:write-bit-array-file function on TI Explorer and |
| |
|
27 |
Symbolics lisp machines. |

Multi-plane bitmaps on lisp machines are color; but the |
| |
|
31 |
lispm image file format does not include a color map, so we |
| |
|
32 |
must treat it as a graymap instead. This is |
| |
|
33 |
unfortunate. |

!!BUGS |
| |
|
39 |
|
| |
|
40 |
|
| |
|
41 |
The Lispm bitmap file format is a bit quirky; Usually the |
| |
|
42 |
image in the file has its width rounded up to the next |
| |
|
43 |
higher multiple of 32, but not always. If the width is not a |
| |
|
44 |
multiple of 32, we don't deal with it properly, but because |
| |
|
45 |
of the Lispm microcode, such arrays are probably not image |
| |
|
46 |
data anyway. |
| |
|
47 |
|
| |
|
48 |
|
| |
|
49 |
Also, the lispm code for saving bitmaps has a bug, in that |
| |
|
50 |
if you are writing a bitmap which is not mod32 across, the |
| |
|
51 |
file may be up to 7 bits too short! They round down instead |
| |
|
52 |
of up, and we don't handle this bug gracefully. |
| |
|
53 |
|
| |
|
54 |
|
| |
|
55 |
No color. |
