This declaration is also used for wires. <em>Object </em>elements are numbered in order of appearance in the file, all other elements are excluded from numbering. These numbers are pure virtual and can not be seen directly in the file.</p> <p>[p1] [p2] [p3] [...] are the required parameters for each element, this differences per element.</p> <p><a href="#0">back to top</a> </p></blockquote><P class="style13"><br> <span class="Head"><a name="3"></a>Wiring</span></P><blockquote> <p>Almost all objects can be interconnected with wires in PureData. Each wire is stored in the file using the following syntax: </p> <p class="code"><strong>#X connect</strong> [source] [outlet_number] [sink] [inlet_number]<strong>;\r\n</strong></p> <p>[source] Is the number of the object the data is coming from. [outlet-number] Represents the number of the outlet of the source object where the wire starts. Sequentially, [sink] is the number of the target object, and finally [inlet_number] specifies inlet of the target object to which the wired is connected.<br> Logically, the objects (again, <strong>connect</strong>s excluded) are numbered from 0 to the total number of objects in the file using the integer format. The inlets and outlets are numbered likewise.<br> Please keep this in mind, to prevent making often made off-by-one errors.</p> <p><a href="#0">back to top</a> </p></blockquote><P class="style13"><br> <span class="Head"><a name="4"></a>Elements and objects </span></P><blockquote> <p>There's a difference between elements and objects. Elements are the parts that together make up the entire layout of a patch, including windowsizes and position. Objects are the building blocks of PureData that contain functionality, gui-related or not. </p> <p>All other <strong>elements</strong> are used to build actual PureData objects:</p></blockquote><ul> <li>array - visual two dimensional array</li> <li>canvas - specifications for the windowsizes and position </li> <li>coords - used for graphs </li> <li>floatatom - number</li> <li>msg - message</li> <li>obj - object, empty, subpatch or gui: <ul> <li>bang</li> <li>toggle</li> <li>nbx</li> <li>vslider</li> <li>hslider</li> <li>vu</li> <li>canvas - gui element</li> <li>pd [name]</li> <li>[name]</li> </ul> </li> <li>restore - for exiting subwindows and graphs </li> <li>symbolatom - symbol</li> <li>text - comment</li></ul><blockquote> <p><a href="#0">back to top</a></p></blockquote><p><br> <span class="Head"><a name="5"></a>Common parameters</span></p><ul> <li><em>Positions and size</em>: As PureData uses a graphical interface every gui-related element (object, message, number, symbol, comment, bang, toggle, number2, vslider, hslider, vradio, hradio, vu, canvas, graph, array) have a horizontal and vertical position in the window that holds the (sub)patch.<br> Records of gui elements that have adjustable sizes also contain the horizontal and/or vertical size.<br> Positions and sizes are stored in pixels.<br> Note that in graphs (element: coords) the pixel sizes of its canvas are relative of the coordinates of the graph, when the option &quot;graph on parent&quot; is selected.</li> <li><em>Color</em>: Some graphical elements have color attributes. Per color only one signed integer value is stored that contains the three 8-bit color components (RGB).<br> Formula to calculate color attribute values:<br> <br> <strong>color = ( </strong>[red]<strong> * -65536) + ( </strong>[green]<strong> * -256) + ( </strong>[blue]<strong> * -1)<br> <br> </strong>Where [red], [green], [blue] obviously represent the three color components, their values range from 0 to 255.<br> They apply to the attributes [background color], [front color], [label color] of various elements.</li> <li><em>Fonts</em>: elements that have a unsigned integer [font] attribute (e.g. the element <strong>text</strong>) have a choice out of three different fonts:<br> 0 = Courier, 1 = Helvetica, 2 = Times. Courier is the only available fixed width font.<br> The [fontsize] attribute contains the font size in pixels.</li> <li><em>Labels</em>: the many GUI-elements that have a [label] attribute can be named. In its label string no spaces ASCII code 32 is allowed. It will generally be recognized as a seperator character for the next parameter/attribute.</li> <li><em>Other parameters</em>: Because of the difference between element parameters there is no default syntax for all elements. They may or may not look much like other elements, depending on their visual and functional similarities.</li></ul><blockquote> <p><a href="#0">back to top</a></p> </blockquote><br><hr width="100%" size="2" noshade><p> <span class="Head"><a name="6"></a>Reference</span></p><ul> <li><a href="#r1">A</a></li> <li><a href="#r2">N</a><ul> <li><a href="#r21">canvas</a></li> </ul> </li> <li><a href="#r3">X</a><ul> <li><a href="#r31">array</a></li> <li><a href="#r32">connect</a></li> <li><a href="#r33">coords</a></li> <li><a href="#r34">floatatom</a></li> <li><a href="#r35">msg</a></li> <li><a href="#r36">obj</a> <ul> <li><a href="#r361">bng</a></li> <li><a href="#r362">tgl</a></li> <li><a href="#r363">nbx</a></li> <li><a href="#r364">vsl</a></li> <li><a href="#r365">hsl</a></li> <li><a href="#r366">vradio</a></li> <li><a href="#r367">hradio</a></li> <li><a href="#r368">vu</a></li> <li><a href="#r369">cnv</a></li> </ul> </li> <li><a href="#r37">[name]</a></li> <li><a href="#r38">pd [name]</a></li> <li><a href="#r39">restore</a></li> <li><a href="#r3A">symbolatom</a></li> <li><a href="#r3B">text</a></li> </ul> </li></ul><blockquote><p><a href="#0">back to top</a></p></blockquote><br><hr width="100%" size="2" noshade><br><table width="100%" border="0"> <tr bgcolor="#CCCCCC"> <td colspan="2"><a name="r1"></a>A</td> </tr> <tr> <td valign="top"><div align="right">Description:</div></td> <td>Announces array data </td> </tr> <tr> <td width="85" valign="top"><div align="right">Syntax:</div></td> <td><span class="code"><strong>#A </strong>[p1] [p2] [p3] [...]<strong>;\r\n</strong></span></td> </tr> <tr> <td width="85" valign="top"><div align="right">Parameters:</div></td> <td>[p1] [p2] [p3] [...] floating point variables representing array elements</td> </tr> <tr> <td width="85" valign="top"><div align="right">Example:</div></td> <td>See Array</td> </tr> <tr> <td valign="top"><div align="right">Remarks:</div></td> <td>Used only in combination of an array definition </td> </tr></table><blockquote> <p><a href="#6">back to reference index</a></p> <p>&nbsp;</p></blockquote><table width="100%" border="0"> <tr bgcolor="#CCCCCC"> <td colspan="2"><a name="r2"></a>N</td> </tr> <tr> <td valign="top"><div align="right">Description:</div></td> <td>Announces a frameset</td> </tr> <tr> <td width="85" valign="top"><div align="right">Syntax:</div></td> <td><span class="code"><strong>#N </strong>[new_frame]<strong>;\r\n</strong></span></td> </tr> <tr> <td width="85" valign="top"><div align="right">Parameters:</div></td> <td>[new_frame] new frameset, currently only a new patchwindow can be defined</td> </tr> <tr> <td width="85" valign="top"><div align="right">Example:</div></td> <td>see canvas</td> </tr> <tr> <td valign="top"><div align="right">Remarks:</div></td> <td>Currently used only for new canvas definitions</td> </tr></table><blockquote> <p><a href="#6">back to reference index</a></p> <p>&nbsp;</p></blockquote><table width="100%" border="0"> <tr bgcolor="#CCCCCC"> <td colspan="2"><a name="r21" id="r21"></a>canvas</td> </tr> <tr> <td valign="top"><div align="right">Description:</div></td> <td>Defines window properties</td> </tr> <tr> <td width="85" valign="top"><div align="right">Syntax:</div></td> <td><span class="code"><strong>#N canvas </strong>[x_pos] [y_pos] [x_size] [y_size] [name] [open_on_load]<strong>;\r\n</strong></span></td> </tr> <tr> <td width="85" valign="top"><div align="right">Parameters:</div></td> <td>[x_pos] - horizontal position offset of frameset (window)<br> [y_pos] - vertical position offset of frameset (window)<br> [x_size] - horizontal size of frameset (window)<br> [y_size] - vertical size of frameset (window)<br> [name] - name / handle of frameset <br> [open_on_load] - when flag is set the canvas is opened when the patch is loaded</td> </tr> <tr> <td valign="top"><div align="right">Example:</div></td> <td class="code">#N canvas 0 0 452 302 12;</td> </tr> <tr> <td width="85" valign="top"><div align="right">Example:</div></td> <td class="code"> #N canvas 0 0 452 302 thiscanvas 0;<br> #X restore 41 136 pd thiscanvas;</td> </tr> <tr> <td valign="top"><div align="right">Remarks:</div></td> <td>In this example patch there are two canvas definitions.<br> The first example has a special syntax, the attributes [name] and [open_on_load] have been replaced by a [font_size] attribute.
