java – 如何在图像周围包装文本？
作者：互联网
我正在尝试将文本包装在图像周围.
我需要创建的结构如下图所示：
这就是我尝试过的
我试过使用没有成功的表.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和它的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元素中的表达式是：
"<img src= '$F{Image}' align='left'/> <p>"+$F{KN_Zusatzinfo_DV_Einleitungstext} +"</p>"
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：
"<style>.left { float: left; margin-left: 1em; width :40%;}</style><p><img class = left src= C:/Users/iman/JaspersoftWorkspace/Qreport/sample1.png />
如果我只使用带有文本框的图像元素,那么输出和设计视图就像这些图片一样：
HTML方法的HTML源代码是：

我怎样才能实现这种结构？
解决方法:
如果你使用html组件在图像周围包装文本,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,因此内容可能会根据文本长度调整大小/剪裁和html(图像)组件上的设置.
我建议在图像周围使用两个textField(参见jrxml),然后计算文本在下一个字段中的位置,这样你就可以在第一个textField获得文本的第一部分,在第二个textField获得第二部分
用于计算文本断点的Java代码
此代码演示了如何使用FontMetric计算Jasper Report将根据textField的大小分解文本的位置(代码的说明在注释中).代码在NullPointer(空文本)和非溢出文本上并不是完全安全的,而且它可以进行优化,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,我使用了一个带有一些arbitrary sample文本的参数. WrapImage类位于类路径中.我将变量设置为计算的断点.然后在文本上使用substring来获取第一个textfield中的第一个部分,第二个使用textField中的第二部分为了简化示例,我使用的是来自桌面的图像,以便如何从数据库中提取图像请参阅：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>
