图片
"type":"pic","val":[{"url":"","w":"","h":"","isRound":"","loop":""},{"url":"","w":"","h":"","isRound":"","loop":""}]
说明：
url节点保存图片地址。
W节点保存图片宽度
H节点保存图片高度
isRound节点代表是否是圆角
loop节点标识是否轮播
报表制作：如果只选择了类型为“图片”对应的属性串为空时，服务器端取当前单元格图片或图片字段对应的图片拼到JSON中。如果属性串不为空时，取属性串中设置的图片。图片的url同单元格图片的格式，也支持相对路径和绝对路径。移动服务器端根据设置的值，进行url拼接。
相对路径：
[{"url":"/mis2/geeznmobile/tempImg/bbb.png","w": "150","h":"150","isRound":"false","loop": "false"},{"url":" /mis2/geeznmobile/tempImg/g.png","w": "150","h": "150","isRound": "true","loop": "true"}]
服务器处理后的串：
"type":"pic","val":[{"url":"http://192.168.1.101:8800/reportmis /mis2/geeznmobile/tempImg/bbb.png","w":"150","h":"150","isRound":"false","loop":"false"},{"url":"http://192.168.1.101:8800/reportmis/mis2/geeznmobile/tempImg/g.png","w": "150","h": "150","isRound": "true","loop": "true"}]
