如何在图像周围包装文字？ [英] How to wrap text around an image?
本文介绍了如何在图像周围包装文字？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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：
这就是我的尝试
我有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元素来解决问题。
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：
< 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片元素，那么输出和设计视图就像这些图片一样：
HTML源代码的html方法是：

何我可以实现这种结构吗？
解决方案
如果你使用html组件来包装图像周围的文字，你不仅有从图像中提取图像的问题吗？数据库，html组件也创建了一个html的图像，因此可以根据html（图像）组件的文本长度和设置调整内容的大小。
I建议在图像周围使用两个 textField s（参见jrxml），然后计算文本在下一个字段中的位置，这样就可以获得第一个文本的第一部分 textField ，第二部分在第二个 textField
Java代码到计算文本的断点
此代码演示了如何使用 FontMetric 来计算Jasper报告将取决于文本的位置关于 textField 的大小（代码的说明在注释中）。代码在 NullPointer （ null 文本）和非溢出文本上并非完全安全，此外它可以是优化，但我会把它留给OP

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;

//the break position is space

jrxml example using java code
In this short example, I use a parameter with some
I'm trying to wrap my text around an Image.
The structure I need to create is as in the picture bellow:
This is what I have tried
I have tried using table which did not succeed. I tough of using text field as html and passing image to it and set the alignment to left, but I found out that it is not possible to pass the image in text field. I started to solve the problem using jaspersoft Studio pro and with its html element. However I could not figure out how to pass the image field from data base as the html source. The expression in the html element is:
"<img src= '$F{Image}' align='left'/> <p>"+$F{KN_Zusatzinfo_DV_Einleitungstext} +"</p>"
This code does not show the image, but a box instead of the image. And the text which is printed is not stretched. The page style which I use is two column. The HTML out put is as in the picture
Using a static path like one bellow to an image works, but it is not an option for me since I need to read the Image from data base:
"<style>.left { float: left; margin-left: 1em; width :40%;}</style><p><img class = left src= C:/Users/iman/JaspersoftWorkspace/Qreport/sample1.png />
If I just use an Image Element with a text box under that the out put and design view are as these pictures:
The HTML source of the html approach is:

How can I achieve this structure?
解决方案
If you use the html component to wrap text around image, not only do you have a problem of pulling the image from the database, the html component also creates an image of the html, hence the content may be resized/clipped depending on text length and settings on html (image) component.
I would suggest to use two textFields wrapped around the image (see jrxml) and then calculate where the text will break into next field, so you get first part of text in first textField and second part in second textField
Java code to calculate text's break point
This code demonstrate how you can use FontMetric to calculate where Jasper Report will break the text depending on the size of your textField (explanation of code is in comments). The code is not perfectly safe on NullPointer (null text) and on non over-flowing text, furthermore it can be optimized but I will leave this to 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
* @param text, the text
* @param width, width of component
* @param font, the font used
* @param frc, the FontRenderContext
* @return
*/
protected static int getLineBreakPosition(String text, int width, Font font, FontRenderContext frc){
int breakPos = 0;
String tmpText = text;
while (font.getStringBounds(tmpText, frc).getWidth()>width){
//the break position is space
breakPos = tmpText.lastIndexOf(' ');
if (breakPos<=0){
breakPos = 0;
break;
}
tmpText = tmpText.substring(0,breakPos);
}
return breakPos;
}
}
jrxml example using java code
In this short example, I use a parameter with some arbitrary sample text. The WrapImage class is in class path. I set a variable to the calculated break point. Then use substring on the text to get first part in first textfield, second in second textField To simplify example, I'm using an image from desktop, for how to pull image from database see: Using images stored in database

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.
