iReport - 动态图像或图像高度
iReport/JasperReports 出现问题，但不确定解决该问题的最佳方法。该报告是典型的订单详细信息样式报告，每个行项目都枚举了数量、描述、名称、价格等属性。
但是，我想解决的问题是显示可选图片作为行项目描述的一部分。每个订单项可以有 N 张详细图片 - 将其视为产品的多个图像（例如汽车引擎盖下、车轮、内部、外部等）。图像数量在运行时显示。
我怎样才能包含这些动态图像？我可以为 9 个图像创建占位符，如果未传入它们则隐藏它们，但这将为没有那么多图像的行项目留下空白。在传递给报告之前，我什至可以将所有杂项图像组合成一个更大的图像，但我仍然遇到尺寸问题。
似乎无法弄清楚如何在带上动态调整大小，同时仍然允许多个可选图像。
有什么想法吗？
having an issue with iReport/JasperReports and not sure the best way to tackle it. The report is a typical order detail style report with each line item enumerated with attributes like quantity, description, name, price, etc.
However, the problem I would like to solve revolves around displaying optional pictures as part of the line item description. Each line item could have N number of detailed pictures - think of it as multiple images of a product (like under the car hood, the wheels, interior, exterior, etc). The number of images is displayed at run time.
How can I include these dynamic images? I could create placeholders for 9 images, and hide if they aren't passed in, but that would leave blank space for the line items that don't have that many images. I could even combine all of the misc images into one bigger image before I passed to the report, but I still have the sizing issue.
Can't seem to figure out how to have dynamic sizing on the band, while still allowing multiple optional images.
Any ideas out there?

解决您的空白问题。您可以将带区设置为在没有数据时不打印（每个图片/项目需要 1 个带区。或者每个组件都有一个属性“空白时删除行”，如果没有数据/图像可显示，该属性将压缩空间在那水平空间上。
To solve your issue with blank space. You can set the band to not print when there is no data (would require 1 band for each picture/item. Or each component has a property 'Remove Line When Blank' which will compact the space if there is no data/images to show on that horizontal space.
