Adds a color layer with data from an image.
- Parameters
-
| [in] | image | the image to be added (BGR format). |
| [in] | layer | the layer that is filled with the image. |
| [out] | gridMap | the grid map to be populated. |
- Returns
- true if successful, false otherwise.

inlinestatic |
Adds a layer with data from image.
- Parameters
-
| [in] | image | the image to be added. If it is a color image (bgr or bgra encoding), it will be transformed in a grayscale image. |
| [in] | layer | the layer that is filled with the image data. |
| [out] | gridMap | the grid map to be populated. |

inlinestatic |
Initializes the geometry of a grid map from an image. This changes the geometry of the map and deletes all contents of the layers!
- Parameters
-
| [in] | image | the image. |
| [in] | resolution | the desired resolution of the grid map [m/cell]. |
| [out] | gridMap | the grid map to be initialized. |
| [in] | | |

inlinestatic |
Creates a cv mat from a grid map layer. This conversion sets the corresponding black and white pixel value to the min. and max. data of the layer data.
- Parameters
-
| [in] | grid | map to be added. |
| [in] | layer | the layer that is converted to the image. |
| [in] | encoding | the desired encoding of the image. |
| [in] | lowerValue | the value of the layer corresponding to black image pixels. |
| [in] | upperValue | the value of the layer corresponding to white image pixels. |
| [out] | image | the image to be populated. |
- Returns
- true if successful, false otherwise.
