The Assemble HSB component assembles an image from the supplied H, S and B channels according to the HSB color model. H, S and B stand for hue, saturation and brightness respectively. For more information on the HSB color model (also known as HSV), see this Wikipedia article on the HSB color model. Assemble HSB is a map component, it can be located in the Channels category on the Components Bar. This component can output HDR colors.
Since all the channels are supplied by map inputs, their values can be controlled separately for different image areas by connecting a map component to the corresponding input. In this case the output brightness of the map component defines the channel value: black areas correspond to the value of 0, white areas to the maximum channel value (360 for the H channel and 100 for S and B), and the values in-between are represented by intermediate brightness levels.
The alpha channel of the image produced by this component is always set to 100%; to set a different alpha channel, use the Set Alpha component.
H: Map Input
Defines the value of the Hue channel in the range between 0 and 360. Value of 0 yields red hue, 120 yields green, 240 — blue, and 360 yields red again; intermediate values yield hues such as cyan, magenta and yellow. Since H is a map input, its value can be controlled separately for different image areas by connecting a map component to this input.
S: Map Input
Defines the value of the Saturation channel in the range between 0 and 100. With the value of 0, the color is completely desaturated; with the value of 100, the color is most saturated. Since S is a map input, its value can be controlled separately for different image areas by connecting a map component to this input.
Defines the value of the Brightness channel in the range between 0 and 100. Value of 0 yields black; with the value of 100, the color has the maximum brightness. Since B is a map input, its value can be controlled separately for different image areas by connecting a map component to this input. This input can accept HDR colors.
