## Detailed Description

A window in a raster including pixels in [xStart, xStop) and [yStart, yStop).

## Member Function Documentation

## ◆ clampX()

int gdal::viewshed::Window::clampX | ( | int | nX | ) | const
| inline

Clamp the argument to be in the window in the X dimension.

Parameters

  nX | Value to clamp.

Returns
  Clamped value.

## ◆ clampY()

int gdal::viewshed::Window::clampY | ( | int | nY | ) | const
| inline

Clamp the argument to be in the window in the Y dimension.

Parameters

  nY | Value to clamp.

Returns
  Clamped value.

## ◆ contains()

bool gdal::viewshed::Window::contains | ( | int | nX,
|  | int | nY
| ) |  | const
| inline

Determine if the window contains the index.

Parameters

  nX | X coordinate of the index to check
  nY | Y coordinate of the index to check

Returns
  True if the index is contained, false otherwise.

## ◆ containsX()

bool gdal::viewshed::Window::containsX | ( | int | nX | ) | const
| inline

Determine if the X window contains the index.

Parameters

  nX | Index to check

Returns
  True if the index is contained, false otherwise.

## ◆ containsY()

bool gdal::viewshed::Window::containsY | ( | int | nY | ) | const
| inline

Determine if the Y window contains the index.

Parameters

  nY | Index to check

Returns
  True if the index is contained, false otherwise.

## ◆ shiftX()

void gdal::viewshed::Window::shiftX | ( | int | nShift | ) |
| inline

Shift the X dimension by nShift.

Parameters

  nShift | Amount to shift
