◆ get_view() [1/2]
|
inlinevirtualinherited |
Create a read/write view of the data.
Modifying this view might modify the actual data. If you want to modify this data in place, call put_view after you done, and it should work efficiently. This function will always return a multi-plane scalar-pixel view of the data.
- Returns
- 0 if unable to get view of correct size, or if resource is write-only.
If you want to fill an existing view (e.g. a window onto some other image), then use
vil_reformat(data->get_view(..), window);

◆ nlevels()

In principle, the number of levels is undefined since the j2k decoder can decompress to any window size. A reasonable strategy is to define the number of levels so that the lowest scale produces a smallest image dimension of 1K pixels
Defined to assign 1000 pixels to the largest dimension of the least resolution level
Implements vil_pyramid_image_resource.
Definition at line 84 of file vil_j2k_pyramid_image_resource.cxx.
