Public Types | |
typedef void | cached_location_t |
type to store relative location for efficient repeated access (not really void) | |
Public Member Functions | |
Image::Pixel & | operator* () |
Dereference a locator, returning a reference to a Pixel. | |
Image::Pixel & | operator() (int x, int y) |
Dereference a pixel offset by (x, y) from the current locator, returning a reference to a Pixel. | |
xy_x_iterator | x () |
Return an x_iterator that can move an xy_locator | |
xy_y_iterator | y () |
Return an y_iterator that can move an xy_locator | |
cached_location_t | cache_location (int x, int y) |
Store a relative location for faster repeated access. | |
Image::Pixel & | operator[] (cached_location_t const &) |
Dereference a cached_location_t , returning a reference to a Pixel. | |
An ImageBase locator.

typedef void lsst::afw::image::imageLocator::cached_location_t |
type to store relative location for efficient repeated access (not really void)
Definition at line 59 of file iterators.cc.
cached_location_t lsst::afw::image::imageLocator::cache_location | ( | int | x, |
int | y ) |
Store a relative location for faster repeated access.
Image::Pixel & lsst::afw::image::imageLocator::operator() | ( | int | x, |
int | y ) |
Dereference a pixel offset by (x, y)
from the current locator, returning a reference to a Pixel.
As a locator
ptr is moved through the image, expressions such as ptr(-1, -1)
can be used to examine or set neighbouring pixels
Image::Pixel & lsst::afw::image::imageLocator::operator* | ( | ) |
Dereference a locator, returning a reference to a Pixel.
Image::Pixel & lsst::afw::image::imageLocator::operator[] | ( | cached_location_t const & | ) |
Dereference a cached_location_t
, returning a reference to a Pixel.
xy_x_iterator lsst::afw::image::imageLocator::x | ( | ) |
Return an x_iterator
that can move an xy_locator
xy_y_iterator lsst::afw::image::imageLocator::y | ( | ) |
Return an y_iterator
that can move an xy_locator
