如何在图像周围包装文字？
我正在尝试将文字包裹在图像周围。
我需要创建的结构如下图所示：
这就是我尝试过的
我尝试使用没有成功的表。我很难将文本字段用作html并将图像传递给它并将对齐设置为左边，但我发现无法在文本字段中传递图像。我开始使用 jaspersoft Studio pro 及其 html元素解决问题。 但是我无法弄清楚如何将数据库中的图像字段作为html源传递。 html元素中的表达式为：
"<style>.left { float: left; margin-left: 1em; width :40%;}</style><p><img class = left src= C:/Users/iman/JaspersoftWorkspace/Qreport/sample1.png />
此代码不显示图像，而是显示框而不是图像。 并且打印的文本没有被拉伸。我使用的页面样式是两列。 HTML输出如图所示
使用像图像一样的静态路径可以工作，但它不是我的选择，因为我需要从数据库中读取图像：

Image元素加上文本字段的HTML源代码为：
A我如何实现这种结构？
1 个答案:
答案 0 :(得分：3)
如果你使用html组件来包装图像周围的文本，不仅你有从数据库中提取图像的问题，html组件也会创建一个html的图像，因此内容可能会调整大小/剪裁取决于on html（image）component上的文本长度和设置。
我建议在图像周围使用两个textField（请参阅jrxml），然后计算文本在下一个字段中的位置，这样就可以在第一个textField中获得文本的第一部分第二部分textField
用于计算文本断点的Java代码
此代码演示了如何使用FontMetric来计算Jasper报告将根据textField的大小来解析文本的位置（代码的说明在注释中）。代码在NullPointer（null文本）和非流动文本上并不完全安全，此外它可以进行优化，但我会将其留给OP

使用java代码的jrxml示例
在这个简短的例子中，我使用带有arbitrary sample文本的参数。 WrapImage类在类路径中。我将变量设置为计算的断点。然后在文本上使用substring获取第一部分textfield，第二部分textField为了简化示例，我使用桌面图片，了解如何提取图片从数据库中看到：Using images stored in database

Be welcoming and patient, especially with those who may not know everything you do. Oh, and bring your sense of humor. Just in case. That basically covers it. But these three guidelines may help: Rudeness and belittling language are not okay. Your tone should match the way you'd talk in person with someone you respect and whom you want to respect you. If you don't have time to say something politely, just leave it for someone who does. Be welcoming, be patient, and assume good intentions. Don't expect new users to know all the rules — they don't. And be patient while they learn. If you're here for help, make it as easy as possible for others to help you. Everyone here is volunteering, and no one responds well to demands for help. Don't be a jerk. These are just a few examples. If you see them, flag them. In summary, have fun, and be good to each other."]]></defaultValueExpression>
