Colormap interface.
This C++ pure virtual class describes the interface to a generic colormap. It is currently tailored to the YUV colorspace.

Get deepness of colormap.
The deepness is the maximum value of depth().

Adds the given colormap to this colormap.
This operator takes the given colormap and compares it to this colormap. If this colormap has C_OTHER or C_BACKGROUND the value is compied from the other LUT, otherwise the value is kept as is.
cmlt | other colormap to add |
Implemented in firevision::YuvColormap.
|
pure virtual |
Convenience method for the method above.
This adds the colormap as in the above method but instead of an instantiated colormap it takes the path to a colormap file which is loaded and added.
filename | file name of colormap to add |
Implemented in firevision::YuvColormap.
|
pure virtual |
Reset colormap.
Resets all values to return C_UNKNOWN for every query with determine().
Implemented in firevision::YuvColormap.
|
pure virtual |
Set color class for given YUV value.
y | Y value from YUV colorspace |
u | U value from YUV colorspace |
v | V value from YUV colorspace |
c | class for the given YUV color |
Implemented in firevision::YuvColormap.
|
pure virtual |
Set to the given raw buffer.
buffer | buffer to copy data from |
Implemented in firevision::YuvColormap.
|
pure virtual |

Create image from LUT.
Create image from LUT, useful for debugging and analysing. This method produces a representation of the given level (Y range with 0 <= level < depth) for visual inspection of the colormap. The dimensions of the resulting image are 512x512 pixels. It uses standard strong colors for the different standard color classes. C_UNKNOWN is grey, C_BACKGROUND is black (like C_BLACK). If the standard method does not suit your needs you can override this method.
yuv422_planar_buffer | contains the image upon return, must be initialized with the appropriate memory size before calling, dimensions are 512x512 pixels. |
level | the level to draw, it's a range in the Y direction and is in the range 0 <= level < depth. |
