this class represents 32 bit images. |
|
40 |
Only the minimum protocol is implemented here; much more is |
|
41 |
needed for higher performance operations on depth32 images. |
|
42 |
(however, 32bit images are very seldom used, so falling back into the |
|
43 |
slow general methods from Image should not hurt too much ..) |
