java - 如何在图像周围环绕文字?

我正在尝试将我的文本环绕在图像周围。

我需要创建的结构如下图所示:

enter image description here

这是我试过的

我试过使用表,但没有成功。我很难将文本字段用作 html 并将图像传递给它并将对齐方式设置为左侧,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 来解决问题。但是我不知道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:

"<img src= '$F{Image}' align='left'/> <p>"+$F{KN_Zusatzinfo_DV_Einleitungstext} +"</p>"

此代码不显示图像,而是显示一个框而不是图像。并且打印的文本没有被拉伸(stretch)。我使用的页面样式是两栏。 HTML 输出如图所示

example output

使用像下面这样的静态路径到图像是可行的,但这对我来说不是一个选项,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 />

如果我只是使用一个带有文本框的图像元素,输出和设计 View 如下图所示:

Image and text field approach

我怎样才能实现这个结构?

最佳答案

如果您使用 html 组件将文本环绕在图像周围,您不仅会遇到从数据库中提取图像的问题,html 组件还会创建 html 的图像,因此内容可能会根据需要调整大小/剪裁关于文本长度和 html(图像)组件的设置。

我建议使用两个 textField 环绕图像(参见 jrxml),然后计算文本将在何处进入下一个字段,这样您就可以在第一个 中获得文本的第一部分textField 和第二部分 textField

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 Report 将根据 textField 的大小中断文本的位置(代码说明在注释中)。该代码在 NullPointer(null 文本)和非溢出文本上​​不是完全安全的,此外它可以优化,但我会把它留给 OP

import java.awt.Font;
import java.awt.font.FontRenderContext;
import java.awt.geom.AffineTransform;

public class WrapImage {

/**
* Get position where string will break
* @param text, the text
* @param width, the width of the component
* @param height, the height of the component
* @return the position
*/
public static int getBreakPosition(String text, int width, int height){
//Start font context
AffineTransform affinetransform = new AffineTransform();
FontRenderContext frc = new FontRenderContext(affinetransform,true,true);

//Set same font as used in jasper-report
Font font = new Font("SansSerif", Font.PLAIN, 10);
//Get height to understand how many lines
double textheight = font.getStringBounds(text, frc).getHeight();
int nrLines = (int)Math.floor(height/textheight);

//init variables
int breakPos = 0;
int line = 1;

//loop the lines
while (line<=nrLines){
//get remaining text
String textPart = text.substring(breakPos,text.length());
//get how much text will fit in line
breakPos += getLineBreakPosition(textPart, width, font, frc)+1;
line++;
}

return breakPos;

}

/**
* Get where a single line will break

使用java代码的jrxml例子

在这个简短的例子中,我使用了一个带有一些 arbitrary sample 的参数文本。 WrapImage 类位于类路径中。我将一个变量设置为计算出的断点。然后在文本上使用 substring 以在第一个 textfield 中获取第一部分,在第二个 textField 中获取第二部分 为了简化示例,我使用了来自桌面,有关如何从数据库中提取图像的信息,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>
