			[b]Black &amp; White:[/b] Pixels whose HSV value is greater than the [member threshold] will be considered as "enabled" (bit is [code]true[/code]). If the pixel is lower than or equal to the threshold, it will be considered as "disabled" (bit is [code]false[/code]).
			[b]Alpha:[/b] Pixels whose alpha value is greater than the [member threshold] will be considered as "enabled" (bit is [code]true[/code]). If the pixel is lower than or equal to the threshold, it will be considered as "disabled" (bit is [code]false[/code]).
