PHP特區 : [轉貼]dotProject 的甘特圖中文修改

Header( "Content-type: image/gif" );
$im = imagecreate( 400, 150 );
$black = ImageColorAllocate( $im, 0, 0, 0 );
$white = ImageColorAllocate( $im, 255, 255, 255 );
$fnt = "/usr/share/fonts/corefonts/fireflysung.ttf";
$str = iconv("BIG5","UTF-8","中文");
ImageTTFText($im, 30, 0, 50,50, $white, $fnt, $str);
ImageGif($im);
ImageDestroy($im);
?>

如果這裡沒問題，代表 PHP、GD 沒問題了～

1. 加入 DEFINE("TTF_DIR"," /usr/share/fonts/corefonts/");
2. 將 DEFINE('CHINESE_TTF_FONT','bkai00mp.ttf');
   改為 DEFINE('CHINESE_TTF_FONT',' fireflysung.ttf');
   

1. 取消內建的 UTF-8 轉碼

   由於本來就是使用UTF-8，所以要把內部的自動轉換關閉。
   搜尋「iconv」，找到

   elseif( $aFF === FF_CHINESE ) {
      if( !function_exists('iconv') ) {
          JpGraphError::RaiseL(25006);
   //('Usage of FF_CHINESE (FF_BIG5) font family requires that your PHP setup has the iconv() function. By de$
      }
      return iconv('BIG5','UTF-8',$aTxt);
   )

   修改為

   
   

   elseif( $aFF === FF_CHINESE ) {
      return $aTxt;
   }

2. 修改字型對應
   

   找到

   FF_CHINESE => array(FS_NORMAL=>CHINESE_TTF_FONT, FS_BOLD=>'', FS_ITALIC=>'', FS_BOLDITALIC=>''),

   修改成

   FF_CHINESE => array(FS_NORMAL=>CHINESE_TTF_FONT, FS_BOLD=>CHINESE_TTF_FONT, FS_ITALIC=>CHINESE_TTF_FONT, FS_BOLDITALIC=>CHINESE_TTF_FONT ),

   如果要設定粗體、斜體為不同字型，要另外設定別的字型檔給 FS_BOLD、FS_ITALIC。

3. 加入區域偵測
   

   應該是用來設定日期的格式的，原則上應該是要給正確的值給他，但是寫在這比較方便。
   找到 function Set($aLocale)，在下方加入

   $query = "SELECT 'config_value' FROM 'config' WHERE 'config_name = host_locale'";
   $aLocale = mysql_query ($query);
   

include ("../jpgraph.php");
include ("../jpgraph_gantt.php");
$bar1 = new GanttBar(0, iconv("BIG5","UTF8","中文 1"),"2001-12-21","2002-01-20");
$bar1->SetCSIMTarget('#','Go back 1');
$bar1->title->SetCSIMTarget('#','Go back 1 (title)');
$bar1->title->SetFont( FF_CHINESE, FS_NORMAL, 8 );
$bar2 = new GanttBar(1,"Activity 2","2002-01-03","2002-01-25");
$bar2->SetCSIMTarget('#','Go back 2');
$bar2->title->SetCSIMTarget('#','Go back 2 (title)');
$graph = new GanttGraph(500);
$graph->title->Set("Example with image map");
$graph->ShowHeaders(GANTT_HYEAR | GANTT_HMONTH | GANTT_HDAY | GANTT_HWEEK);
$graph->scale->week->SetStyle(WEEKSTYLE_FIRSTDAY);
$graph->scale->week->SetFont(FF_FONT1);
$graph->Add(array($bar1,$bar2));
// And stroke
$graph->StrokeCSIM('ganttcsimex01.php');
?> 

如果這裡沒問題，應該代表 jpgraph 的設定沒問題。

1. 取消內建的 UTF-8 轉碼

   由於本來就是使用UTF-8，所以要把內部的自動轉換關閉。

   找到

   if ( $locale_char_set=='utf-8' && function_exists("utf8_decode") ) {
    $name = strlen( utf8_decode($p["project_name"]) ) > 25 ? substr( utf8_decode($p["project_name"]), 0, 22 ).'...' : utf8_decode($p["project_name"]) ;
   } else {
    //while using charset different than UTF-8 we need not to use utf8_deocde
    $name = strlen( $p["project_name"] ) > 25 ? substr( $p["project_name"], 0, 22 ).'...' : $p["project_name"] ;
   }

   改成

   $name = strlen( $p["project_name"] ) > 25 ? substr( $p["project_name"], 0, 22 ).'...' : $p["project_name"] ;

2. 修改字型設定
   
   
   1. 找到 //$graph->scale->actinfo->SetFont(FF_ARIAL);
      
      改為 $graph->scale->actinfo->SetFont(FF_CHINESE);
      
   2. 找到

      // Use TTF font if it exists
      // try commenting out the following two lines if gantt charts do not display
      if (is_file( TTF_DIR."arialbd.ttf" ))
       $graph->scale->tableTitle->SetFont(FF_ARIAL,FS_BOLD,12);

      修改為 $graph->scale->tableTitle->SetFont(FF_CHINESE,FS_BOLD,12);

   3. 找到

      $bar->title->SetCOlor('red');
      $graph->Add($bar);

      加入一行，變成

      $bar->title->SetCOlor('red');
      $bar->title->SetFont(FF_CHINESE,FS_BOLD,8);
      $graph->Add($bar);

   4. 找到 $bar->title->SetFont(FF_FONT1,FS_NORMAL,10);
      改為 $bar->title->SetFont(FF_CHINESE,FS_NORMAL,10);
      
   5. 找到
      $bar->caption = new TextProperty($caption);
      在之後加入 $bar->caption->SetFont(FF_CHINESE,FS_NORMAL,10);
      
   6. 找到 $graph->Add($bar2);
      共兩處，在前面加上 $bar2->title->SetFont(FF_CHINESE,FS_NORMAL,10);
      
   7. 找到 $graph->Add($bar3);
      在前面加上 $bar3->title->SetFont(FF_CHINESE,FS_NORMAL,10);
      
   8. 找到 $graph->Add($vline);
      在前面加上 $vline->title->SetFont(FF_CHINESE,FS_BOLD,8);

1. 取消內建的UTF-8轉碼

   由於本來就是使用UTF-8，所以要把內部的自動轉換關閉。

   找到

   
   

   if( $local_char_set==』 utf-8' && function_exists('utf8_decode') ) {
      $name = utf8_decode($name);
   }

   把這三行刪除。

2. 修改字型設定：
   
   
   1. 找到

      if (is_file( TTF_DIR.'arialbd.ttf' )){
         $graph->scale->actinfo->SetFont(FF_ARIAL);
      }

      修改為 $graph->scale->actinfo->SetFont(FF_CHINESE);
      

   2. 找到

      // Use TTF font if it exists
      // try commenting out the following two lines if gantt charts do not display
      if (is_file( TTF_DIR.'arialbd.ttf' ))
      $graph->scale->tableTitle->SetFont(FF_ARIAL,FS_BOLD,12);

      修改為 $graph->scale->tableTitle->SetFont(FF_CHINESE,FS_BOLD,12);
      

   3. 找到 $graph->Add($bar);
      共兩處，在前面加上
      $bar->title->SetFont(FF_CHINESE,FS_NORMAL,10);
      
   4. 找到

      if (is_file( TTF_DIR.'arialbd.ttf' )) {
         $vline->title->SetFont(FF_ARIAL,FS_BOLD,10);
      }

      修改為 $vline->title->SetFont(FF_CHINESE,FS_BOLD,8);
