| static unsigned char* pcl::visualization::FloatImageUtils::getVisualAngleImage | ( | const float * |
angle_image, | | | int |

Use getColorForAngle for all elements of the given arrays.

| | static |
Use getColorForFloat for all elements of the given arrays, whereas the values are first normalized to [0,1], either using the given min/max values or based on the actual minimal and maximal values existing in the array.
The output is a byte array of size 3*width*height containing the colors in RGB order. If gray_scale is true, the outcome will still be an RGB image, but all colors apart for the special colors of non-finite numbers, will be gray values

| | static |
Use getColorForFloat for all elements of the given arrays, whereas the values are normalized to [0,1] with the given min/max values.
The output is a byte array of size 3*width*height containing the colors in RGB order. If gray_scale is true, the outcome will still be an RGB image, but all colors will be gray values.
