In fact, most of the time, RGB images without an alpha channel are only used as background images in the B input, and should be considered as transparent, since they should not occlude anything. That way, the alpha channel on output only contains the opacity of elements that are merged with this background. In some rare cases, though, one may want the RGB image to actually be opaque, and can check the "A" checkbox for the given input to do so.qÕhhh!h"h)h\h+}qÖ(h1]q×h3]qØh/]qÙh-]qÚh5]qÛuh9Kh:hh;]qÜhTXº Note that if an input with only RGB components is connected to A or B, its alpha channel is considered to be transparent (zero) by default, and the "A" checkbox for the given input is automatically unchecked, unless it is set explicitely by the user.
