有PDF模板的情況下，重新繪制PDF

1-  使用 Adobe Acrobat DC 

2-  編輯PDF > 准備表單

代碼中讀取PDF模板，按照排版好的域，順序寫入內容

 

AcroFields form = stamper.getAcroFields();

 

for (String key : dataParamMap.keySet()) {    
                    int ilen = dataParamMap.get(key).toString().length();
                    if(key == "學校" || key == "隊伍"){
                        if(ilen >= 20 && ilen < 40){
                            form.setFieldProperty(key, "textsize", new Float(10), null);
                        }else if(ilen >= 40 && ilen <= 55){
                            form.setFieldProperty(key, "textsize", new Float(7), null);
                        }else if(ilen > 55){
                            form.setFieldProperty(key, "textsize", new Float(6), null);
                        }
                    }
                    
                    form.setField(key,dataParamMap.get(key).toString());
