Eclipse screen shot:The Chinese characters are ok

[kevinwong]

Deploy with this api:

      RepositoryService reposService = (RepositoryService)BeanLoader.getBean("repositoryService");
      Deployment deployment =   reposService.createDeployment().name("UserDemo")
        .addClasspathResource("UserTaskDemo.bpmn20.xml")
        .deploy();

and show in the website with servlet:

  InputStream imageStream =null;
  if(type!=null && type.equals("inst")){
   RuntimeService runtimeService = (RuntimeService)BeanLoader.getBean("runtimeService");
   //ProcessDefinitionEntity pde = (ProcessDefinitionEntity)processDefinition;
   ProcessDefinitionEntity pde = (ProcessDefinitionEntity)((RepositoryServiceImpl) repositoryService).getDeployedProcessDefinition(processDefId);
   if(pde.isGraphicalNotationDefined()){
    System.out.println("isGraphicalNotationDefined:No diagram defined for process definition id ");
   }else{
    ProcessDiagramGenerator.generateDiagram(pde, "png", runtimeService.getActiveActivityIds(processInstanceId));
   }
   imageStream = ProcessDiagramGenerator.generateDiagram(pde, "png", runtimeService.getActiveActivityIds(processInstanceId));
  }else{
   String diagramResourceName = processDefinition.getDiagramResourceName();
   imageStream = repositoryService.getResourceAsStream(processDefinition.getDeploymentId(), diagramResourceName);
  }
  if(imageStream !=null){
   byte[] b_image = new byte[1024];
   while(imageStream.read(b_image)>0)
      {
    response.getOutputStream().write(b_image);
      }
  }

the Chinese characters became square

[kevinwong]

I'm sure it's a bug now,

  public ProcessDiagramCanvas(int width, int height) {
    this.canvasWidth = width;
    this.canvasHeight = height;
    this.processDiagram = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
    this.g = processDiagram.createGraphics();
    g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
    g.setPaint(Color.black);

    Font font = new Font("Arial", Font.BOLD, 11);
    g.setFont(font);
    this.fontMetrics = g.getFontMetrics();
  }

    Font font = new Font("Arial", Font.BOLD, 11);
It seams that Arial doesn't support Chinese, please fix this bug. it's tiny,but tiresome.  maybe we could make it a configuration item?

[wangtao]

Great, should be more comfort for Chinese.
太好了，支持下中国人民吧 :mrgreen:

[kevinwong]

I've created a new issue in jira
http://jira.codehaus.org/browse/ACT-977  I wish it could be fixed in no time  :lol:

顶楼上  :lol:

    Font font = new Font("Microsoft YaHei", Font.BOLD, 11);
is ok, here is the patch
