<p><code>${NSD_SetImage} <i>control_HWND</i> <i>image_path</i> <i>output_variable</i></code></p>
|

|

<p>Loads a bitmap from <i>image_path</i> and displays it on <i>control_HWND</i> created by <a href="#mref-create">${NSD_CreateBitmap}</a>. The image handle is stored in <i>output_variable</i> and should be freed using <a href="#mref-freeimage">${NSD_FreeImage}</a> once no longer necessary.</p>
|
||||
|
||||
<p>The image must be extracted to the user's computer prior to calling this macro. A good place to extract images is $PLUGINSDIR.</p>
