In theory InverseDCT(ForwardDCT(yuv)) = yuv, that is, an image can be converted to DCT and back to its original. <p> <hr><h2>Constructor & Destructor Documentation</h2> <a name="a0" doxytag="CDCTPanel::CDCTPanel"></a><p> <table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td nowrap valign="top"><b> CDCTPanel::CDCTPanel ( </b></td> <td valign="bottom"><b> <a class="el" href="class_ccampanel.html">CCamPanel</a> * <em>base_panel</em>, </b></td> </tr> <tr> <td></td> <td><b> bool <em>inv</em>, </b></td> </tr> <tr> <td></td> <td><b> const char * <em>name</em> = "dct.yuv", </b></td> </tr> <tr> <td></td> <td><b> const char * <em>desc</em> = "DCT conversion" ) </b></td> </tr> </table> </td> </tr> </table> <table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td> <p> Constructor. <p> <dl compact><dt> <b>Parameters: </b><dd> <table border=0 cellspacing=2 cellpadding=0> <tr><td valign=top><em>base_panel</em> </td><td> The yuv panel we use as our basis for calculation. </td></tr> <tr><td valign=top><em>inv</em> </td><td> When true, this class performs the IDCT, otherwise FDCT </td></tr> <tr><td valign=top><em>name</em> </td><td> Name for this panel </td></tr> <tr><td valign=top><em>desc</em> </td><td> Description for this panel </td></tr> </table> </dl> </td> </tr> </table> <a name="a1" doxytag="CDCTPanel::~CDCTPanel"></a><p> <table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td nowrap valign="top"><b> CDCTPanel::~CDCTPanel ( </b></td> <td valign="bottom"><b> ) </b></td> </tr> </table> </td> </tr> </table> <table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td> <p> Destructor. <p> <p> Cleans up tiles. </td> </tr> </table> <hr><h2>Member Function Documentation</h2> <a name="g1" doxytag="CDCTPanel::SetSize"></a><p> <table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td nowrap valign="top"><b> void CDCTPanel::SetSize ( </b></td> <td valign="bottom"><b> const QSize & <em>ns</em> )<code> [virtual, slot]</code> </b></td> </tr> </table> </td> </tr> </table> <table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td> <p> [overloaded] Set size, create tiles. <p> <p> Reimplemented from <a class="el" href="class_ccampanel.html#g0">CCamPanel</a>. </td> </tr> </table> <a name="a2" doxytag="CDCTPanel::SetTiles"></a><p> <table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td nowrap valign="top"><b> void CDCTPanel::SetTiles ( </b></td> <td valign="bottom"><b> <a class="el" href="struct_ccamtile.html">CCamTile</a> * <em>tilesy</em>, </b></td> </tr> <tr> <td></td> <td><b> <a class="el" href="struct_ccamtile.html">CCamTile</a> * <em>tilesuv</em> ) </b></td> </tr> </table> </td> </tr> </table> <table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td> <p> Set tiles coordinates. <p> <p> In case you want your own ordering of input-output pixels, or want to share the arrays, use this function to set two arrays of CCamTiles for the Y and UV panels resp.
