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

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?

Is the "Microsoft YaHei" font supported on every JRE on every platform?

Best regards,

Re: Encounter a language support problem

kevinwong — Sat, 05 Nov 2011 04:18:24 GMT

I test this on ubuntu 11.10, win7x64 sp1, aix ,jdk are 1.5 or higher it works ,but i suggest we should make it a config item or a runtime parameter.it will be more flexable
At least , if we hard code Yahe ihere , and Yahe is not support by the platform, it will replace by the default font,and mostly it will be the local font that support Chinese or other non english language.
Anyway, i suggest it should be a runtime parameter with default value Microsoft Yahei.Thanks

Nope. It does not exist on a standard Ubuntu 11.10 installation. Apart from that it is probably designed to render Chinese symbols best, which typically means that Latin characters have a kind of weird (fixed-width) appearance that most western readers are not used to.

Hi，here is the description of yahei font http://en.wikipedia.org/wiki/Microsoft_YaHei

and the screenshot for English and Chinese preview, win7cn default font is ms yahei. So do you still think the Latin characters have a weird appearance? Anyway, jdk will use the system default font to render the characters if the font we specify cannot be found ,the problem here is ,"Arial" could be found(mostly, all platform have this font) , and it doesn't support non-english language. At least, don't use "Arial" here, use Arial Unicode version, it supports a lot of non-english languages.Thanks.

Re: Encounter a language support problem

ahtya — Wed, 21 Dec 2011 12:40:19 GMT

My solution is replace "Arial" with Font.SANS_SERIF.
Original ：
Font font = new Font("Arial", Font.BOLD, 11);My solution ：
Font font = new Font(Font.SANS_SERIF, Font.BOLD, 12);I think it can work with JRE 1.6 on every platform.

Hi, I have provided a solution for this issue - the possibility of defining custom or extending existing ProcessDiagramGenerator. Discussion is here.
Patch for this issue is ready, I'm waiting until my boss lets me to become an Activiti contributor.
