|
|
* Construct a single plane pixmap from bitmap data.

|

|

|
|
* NOTE: This procedure has the correct behavior on Windows and
|
| 27 |
|
|
* the Macintosh, but not on UNIX. This is probably because the

| 28 |
|
|
* emulation for XPutImage on those platforms compensates for whatever

* is wrong here :-)

* Returns a new Pixmap.
