如何编辑被转换成图像的文本？或任何其他的方法来实现/编辑文本 [英] How to edit a text that is converted into image? or any other approach to realize/edit text

问题描述

有关项目中，我要调整的文字，就像在Adobe Photoshop。但是，当我试图调整（通过鼠标拖动）textpane，只有textpane得到了调整，而不是里面的文字。然后我试图转换我的文字图像，并试图调整再次（在后提到如何来调整在Java 文本），它工作得很好。现在我有我的编辑文本的另一个问题。即一旦我的文本转换为图像，然后我怎么编辑（如：改变文字颜色等）。

对此有何想法？

解决方案

  

..一旦我的文本转换为图像，然后我怎么编辑（如：改变文字颜色等）。

不要。这是更好（质量），更容易绘制图像的每个选择与文本要求时，在所需字体，从点，的AffineTransform ， RenderinhHints 和颜色（等）。

..如何编辑图像中的文字？

我通常提供的控制做到这一点是这样的：

不过，当然，这不包括：

1. 颜色，它在主界面控制（基本涂料的应用程序。）结果
   


2. 将拖累作为结果的文本缩放。这可能通过使用可调整大小的元素通过两种@trashgod或证明自己（上图）来实现。

For my project I want to resize text just like in Adobe Photoshop. But when I tried resizing(by mouse drag) the textpane, only the textpane was getting resized and not the text inside it. Then I tried converting my text to image and tried resizing it again (As mentioned in the post How to resize text in java) and it worked fine.. Now I have another problem of editing my text. i.e. once my text is converted to image then how do i edit it (eg: changing the text color, etc).

Any idea on this?

解决方案

..once my text is converted to image then how do I edit it (eg: changing the text color, etc).

Don't. It is better (quality) and easier to paint the image each choice with the text when requested, in the desired Font, starting Point, AffineTransform, RenderinhHints and Color (etc.).

import java.awt.*;
import java.awt.geom.AffineTransform;

import javax.swing.*;

public class StretchLabels {

    String s = "The quick brown fox jumps over the lazy dog!";
    Font font = new Font(Font.SERIF, Font.PLAIN, 24);

    public JComponent getGUI() {
        JPanel gui = new JPanel(new BorderLayout());

        JLabel l1 = new StretchTextLabel(s);
        l1.setFont(font);
        gui.add(l1, BorderLayout.CENTER);

        return gui;
    }

    public static void main(String[] args) throws Exception {
        Runnable r = new Runnable() {
            @Override
            public void run() {
                JFrame f = new JFrame("Streeetch me!");
                f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
                f.setLocationByPlatform(true);

                StretchLabels eg = new StretchLabels();
                f.setContentPane(eg.getGUI());
                f.pack();

                f.setVisible(true);
            }
        };
        SwingUtilities.invokeLater(r);
    }
}

class StretchTextLabel extends JLabel {
    private static final long serialVersionUID = 1L;

    public StretchTextLabel(String s) {
        super(s);
    }

    @Override
    public void paintComponent(Graphics gr) {
        Color c = gr.getColor();
        setForeground(new Color(0,0,0,0));
        super.paintComponent(gr);
        setForeground(c);
        gr.setColor(c);
        Graphics2D g = (Graphics2D)gr; 
        g.setRenderingHint(
                RenderingHints.KEY_TEXT_ANTIALIASING, 
                RenderingHints.VALUE_TEXT_ANTIALIAS_ON);

        double pw = this.getPreferredSize().width;
        double ph = this.getPreferredSize().height;
        double w = this.getSize().width;
        double h = this.getSize().height;

        // Set FG (text) color
        g.setColor(this.getForeground());

        // stretch
        AffineTransform stretch =
                AffineTransform.getScaleInstance(w/pw, h/ph);
        g.setTransform(stretch);
        g.drawString(getText(), 0, this.getFont().getSize());
    }
}

.. how do I edit the text in the image?

I typically offer controls to do it like this:

But of course, that does not cover:

1. Color, which has a control in the main GUI (a basic paint app.)
   
2. Scaling of the resulting text by 'drag'. Which might be achieved by using a resizable element as demonstrated by either @trashgod or myself (above).
