<p>New page: {{FilterCat|External_filters|Other_filters|Support_filters}} {{FuncDef|MaskedMerge (clip base_clip, clip overlay_clip, clip mask_clip) }} &#039;&#039;&#039;Plugin&#039;&#039;&#039;: <a href="/index.php/MaskTools" title="MaskTools">MaskTools</a> This filter applies...</p> <p><b>New page</b></p><div>{{FilterCat|External_filters|Other_filters|Support_filters}}<br /> <br /> {{FuncDef|MaskedMerge (clip base_clip, clip overlay_clip, clip mask_clip) }}<br /> <br /> '''Plugin''': [[MaskTools]]<br /> <br /> This filter applies the clip &lt;tt&gt;overlay_clip&lt;/tt&gt; on the clip &lt;tt&gt;base_clip&lt;/tt&gt;, considering the clip &lt;tt&gt;mask_clip&lt;/tt&gt;. More precisely, with bc, oc and mc the values of three pixels taken respectively on &lt;tt&gt;base_clip&lt;/tt&gt;, &lt;tt&gt;overlay_clip&lt;/tt&gt; and &lt;tt&gt;mask_clip&lt;/tt&gt;, the result will be :<br /> <br /> v = ((256 - mc) * bc + mc * oc + 128) / 256<br /> <br /> 128 is here in order to reduce the error due to the rounding of the integer division.<br /> <br /> So, if the mask is 255, the pixel will be the pixel from the &lt;tt&gt;overlay_clip&lt;/tt&gt;, if the mask is 0, the pixel will be from the &lt;tt&gt;base_clip&lt;/tt&gt;, and in between, it will be blended between both clips.<br /> <br /> ----<br /> Back to [[MaskTools]].</div>
