使用 JasperReports 在每个页面上创建折叠机的 OMR 图像
我们的发票系统需要在发票的每一页上打印 OMR（光学标记识别）符号，以便折叠机知道在信封中放入什么内容，因此必须在每一页上放置小 PNG 图片。 我们的发票由主报告和在特殊 .jrxml 文件中创建的两个子报告组成。图片是通过调用 Web 服务生成的，并在 http 请求中传递页码作为参数。因此，我们需要将图片合并到子报表中，希望子报表在生成文档时能够“知道”实际页码。我们收到的错误是：
Error filling print... Could not resolved style(s): pdf

我们正在使用 JasperReports 3.0.0 - 迁移到较新版本需要进行大量更改，因此目前无法选择，以防我们需要转到较新版本。
Our invoicing system needs to print OMR (optical mark recognition) symbol on each page of our invoices so the folding machine knows what to put in the envelope, so that little PNG picture has to be put on each page.
Our invoice is consisted of main report with two subreports created in special .jrxml files. Picture is generated by calling web service with passing page number as a parameter in http request. So, we need to incorporate picture into subreport hoping that subreport will 'know' actual page number when generating document. Error we are getting is:

We are using JasperReports 3.0.0 - migration to newer version requires lot of changes, so that's for now out of option, in case we need to go to newer version.

通过将图片放在主报告的“背景”带上来解决。图片定期在每个页面上显示一次。
solved with putting picture onto band called 'background' of main report. Picture is being shown regularly on each page once.
