8083	schaersvoo	171	@General syntax <ul><li>The transparency of all objects can be controlled by command 'opacity [0-255],[0,255]'</il><li>a line based object can be controlled by command 'linewidth int'</li><li>a line based object may be dashed by using keyword 'dashed' before the object command.<br />the dashing type can be controled by command 'dashtype int,int'</li><li>a fillable object can be set fillable by starting the object command with an 'f'<br />(like frect,fcircle,ftriangle...)<br />or by using the keyword 'filled' before the object command.<br />The fill colour will be the stroke colour...(19/10/2013)<li> a draggable object can be set draggable by a preceding command 'drag x/y/xy'<br />The translation can be read by javascript:read_dragdrop();
		172	The replyformat is : object_number : x-orig : y-orig : x-drag : y-drag<br />The x-orig/y-orig will be returned in maximium precision...the x-drag/y-drag will be returned in defined 'precision' number of decimals<br />Multiple objects may be set draggable / clickable (no limit)<br /> not all flydraw objects may be dragged / clicked<br />Only draggable / clickable objects will be scaled on zoom and will be translated in case of panning</li><li> a 'onclick object' can be set 'clickable' by the preceding keyword 'onclick'<br />not all flydraw objects can be set clickable</li><li><b>remarks using a ';' as command separator</b><br />commands with only numeric or colour arguments may be using a ';' as command separator (in stead of a new line)<br />commands with a string argument may not use a ';' as command separator !<br />these exceptions are not really straight forward... so keep this in mind.<br />example:<br />size 200,200;xrange -5,5;yrange -5,5;hline 0,0,black;vline 0,0,black<br />plot red,sin(x)<br />drag xy<br />html 0,0,5,-5, &euro; <br />lines green,2,0,2,-2,-2,2,-2,0;rectangle 1,1,4,4,purple;frectangle -1,-1,-4,-4,yellow</li></ul>
