pnmpaste - paste a rectangle into a portable anymap |

!!DESCRIPTION |

|
| |
|
22 |
Reads two portable anymaps as input. Inserts the first |
| |
|
23 |
anymap into the second at the specified location, and |
| |
|
24 |
produces a portable anymap the same size as the second as |
| |
|
25 |
output. If the second anymap is not specified, it is read |
| |
|
26 |
from stdin. The ''x'' and ''y'' can be negative, in |
| |
|
27 |
which case they are interpreted relative to the right and |
| |
|
28 |
bottom of the anymap, respectively. |

This tool is most useful in combination with ''pnmcut''. |
| |
|
32 |
For instance, if you want to edit a small segment of a large |
| |
|
33 |
image, and your image editor cannot edit the large image, |
| |
|
34 |
you can cut out the segment you are interested in, edit it, |
| |
|
35 |
and then paste it back in. |
| |
|
36 |
|
| |
|
37 |
|
| |
|
38 |
Another useful companion tool is |
| |
|
39 |
''pbmmask''. |
| |
|
40 |
|
| |
|
41 |
|
| |
|
42 |
__pnmcomp__ is, a more general tool, except that it lacks |
| |
|
43 |
the |
| |
|
44 |
__pnmcomp__ allows you to specify an alpha |
| |
|
45 |
mask in order to have only part of the inserted image get |
| |
|
46 |
inserted. So the inserted pixels need not be a rectangle. |
| |
|
47 |
You can also have the inserted image be translucent, so the |
| |
|
48 |
resulting image is a mixture of the inserted image and the |
| |
|
49 |
base image. |
| |
|

The optional flag specifies the operation to use when doing |
| |
|
53 |
the paste. The default is __-replace__. The other, |
| |
|
54 |
logical operations are only allowed if both input images are |
| |
|
55 |
bitmaps. These operations act as if white is TRUE and black |
| |
|
56 |
is FALSE. |
| |
|
57 |
|
| |
|
58 |
|
| |
|
59 |
All flags can be abbreviated to their shortest unique |
| |
|
60 |
prefix. |
