Definition at line 226 of file image_ref.h.
| bool CVD::ImageRef::next | ( | const ImageRef & | max | ) | [inline] |
Step to the next co-ordinate in the image (in horizontal scanline order).
Successive calls to this function will work along each row of the image. If the next co-ordinate is off the end of the image, it returns false.

| bool CVD::ImageRef::prev | ( | const ImageRef & | max | ) | [inline] |
Step to the previous co-ordinate in the image (in horizontal scanline order).
Successive calls to this function will work backwards along each row of the image. If the next co-ordinate is off the start of the image, it returns false.

Definition at line 249 of file image_ref.h.
Step to the next co-ordinate in the image (in horizontal scanline order), for pixels within a rectangular window Successive calls to this function will work backwards along each row of the image.
If the next co-ordinate is off the start of the image, it returns false.

| max | The minimum (x,y) co-ordinates in the window |

| bool CVD::ImageRef::operator< | ( | const ImageRef & | other | ) | const [inline] |
An ImageRef is less than another ImageRef if it is earlier in the standard horizontal scan-line order, i.e.
has a smaller y-co-ordinate or the same y-co-ordinate but a smaller x-co-ordinate. An ordering of ImageRefs is needed to allow them to be used in STL for sets, maps, multisets, multimaps etc.
