问题描述

我正在尝试在报告中创建带有文字的水印。对于例如有一个像这样的文本，这是一个很好的报告在报告的背景上反复水平打印。我知道这可以在后台乐队中完成，但不知道如何。

I am trying to create a watermark with a text in a report. For e.g. have a text like this is a good report printed horizontally repeatedly at the background of a report. I know this can be done in the background band but don't know how.

更新
您的解决方案有效。我想以另一种方式实现这一点。我想在后台重复打印相同的文本。假设我想打印文本欢迎来到新的一年。我希望它以这种方式打印

UPDATE Your solution worked. I want to implement this in another way. I want to print the same text repeatedly at the background. Let's say i want to print the text welcome to a new year. I will want it to print this way

welcome to a new year welcome to a new year welcome to a new year welcome to a new year
welcome to a new year welcome to a new year welcome to a new year welcome to a new year
welcome to a new year welcome to a new year welcome to a new year welcome to a new year
welcome to a new year welcome to a new year welcome to a new year welcome to a new year
welcome to a new year welcome to a new year welcome to a new year welcome to a new year
...

所有这些都将在后台。我可以实现这样的事情，而无需手动创建文本字段来填充页面。

All these will be at the background. Can i achieve something like this without manually creating the text fields to fill the page.

推荐答案

是的，你是对的。您可以使用背景波段打印水印文本（或图片）。
您应该为此乐队设置 高度 - 我认为最好将此乐队的高度设置为与报告的高度相同。

Yes, you are right. You can use Background band for printing watermark text (or picture). You should set the height for this band - I think it is better to set height of this band the same as the report's height.

例如，对于 A4 格式，我为背景的波段高度设置了 802 像素。计算此数字的公式为： 报告的高度（ A4 格式的 842 像素） - 左边距宽度（ 20 在我的情况下） - 右边距宽度（ 20 在我的情况下）。

For example, for A4 format I have set the 802 pixels for Background's band height. The formula for calculating this number was: the Report's height (842 pixels for A4 format) - the Left Margin's width (20 in my case) - the Right Margin's width (20 in my case).

设置背景波段的大小后，您可以添加 图像 或 staticText（textField） 此元素（背景）的元素。

After setting size for the Background band you can put image or staticText (textField) elements to this (Background) band.

您可以借助旋转属性旋转 staticText（textField） 元素的文本。此属性的可用值为：

You can rotate the text of staticText (textField) element with help of rotation attribute. The available values of this attribites are:


  • 无（无旋转 - 0度），

  • 左（旋转270度），

  • 右（旋转90度），

  • UpsideDown （旋转180度）。

  • None (no rotation - 0 degrees),
  • Left (rotate 270 degrees),
  • Right (rotate 90 degrees),
  • UpsideDown (rotate 180 degrees).

在工作样本中我'已使用样式为 textField 设置轮换属性，并为一个元素设置了此属性的值直接到 textField 元素：

In the working sample I've used styles for setting the rotation attribute for textField and for one element I've set value for this attribute directly to the textField element:

图片 元素不支持旋转属性，但您可以手动创建所需的任何图像。

The image element does not support the rotation attribute, but you can create any image you want manually.

注意 ：在此示例中，我使用了 mode =Opaque 用于 textField 和 图片 元素。

Note: in this sample I've used mode="Opaque" for textField and image elements.

结果将是（通过 iReport 预览功能）：

The result will be (via iReport preview function):

注意 ：在此示例中我'为 textField 元素使用了 mode =Transparent 。

Note: in this sample I've used mode="Transparent" for textField elements.

报告的设计（在 iReport 中）：

您可以在 JasperReports页面中的水印中找到更多信息如果您想设置自定义旋转角度，请发布。

You can find more information in Watermark across the page in JasperReports post if you want to set custom rotation angle.

更新 ：您可以解决第二个问题，例如，在 StringUtils.repeat（java.lang.String，int）方法来自 Commons Lang API 。

您可以添加 导入 指令（< import value =org.apache.commons.lang3.StringUtils/> 在我的示例中）到你的报告模板并使用如下表达式：

You can add import instruction (<import value="org.apache.commons.lang3.StringUtils"/> in my sample) to your report's template and use the expression like this:

<textFieldExpression><![CDATA[StringUtils.repeat("Welcome to a New Year! ", $P{numberOfRepeats})]]></textFieldExpression>

  • 在此示例中，我'使用 Commons Lang library v.3.1 。您应该将此库添加到应用程序的类路径中（在我的情况下，它是 iReport 的cp）。

  • In this sample I've used the Commons Lang library v. 3.1. You should add this library to the application's classpath (in my case it was iReport's cp).


  • 我使用参数 numberOfRepeats （ java.lang.Integer ）来设置要生成的短语数。

  • I've used the parameter numberOfRepeats (java.lang.Integer) for setting the number of phrases to generate.
