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 60 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 an 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.
