Question

您好我需要java.awt.image.BufferedImage中的bufferedImage对象。如何在codenameone中定义这样的东西？

更新：这是一个我想要移植到codenameone的课程

package org.rajman.map.awt;

import java.awt.image.BufferedImage;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import javax.imageio.ImageIO;

import org.rajman.core.graphics.Bitmap;

class AwtBitmap implements Bitmap {
    final BufferedImage bufferedImage;

    AwtBitmap(InputStream inputStream) throws IOException {
       this.bufferedImage = ImageIO.read(inputStream);
        if (this.bufferedImage == null) {
           throw new IOException("ImageIO filed to read inputStream");
        }
}

AwtBitmap(int width, int height) {
    this.bufferedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
}

@Override
public void compress(OutputStream outputStream) throws IOException {
    ImageIO.write(this.bufferedImage, "png", outputStream);
}

@Override
public void decrementRefCount() {
    // no-op
}

@Override
public int getHeight() {
    return this.bufferedImage.getHeight();
}

@Override
public int getWidth() {
    return this.bufferedImage.getWidth();
}

@Override
public void incrementRefCount() {
    // no-op
}

@Override
public void scaleTo(int width, int height) {
    // TODO implement
}

@Override
public void setBackgroundColor(int color) {
    // TODO implement
}

}

Image.create(width,height,argbBackground)将创建您可以修改的图像。您可以使用该类中的许多静态方法从流或字节数组加载图像，我们有自己的ImageIO API来保存图像。

什么是codenameone中java.awt.image.BufferedImage的替代方法
