CodenameOne中java.awt.image.BufferedImage的替代方案是什么

Question

嗨，我需要類似java.awt.image.BufferedImage中的bufferedImage對象的東西。 如何在codenameone中定義這樣的內容？

更新：這是我想移植到codenameone的類

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)將創建一個可以修改的圖像。 您可以使用該類中的許多靜態方法從流或字節數組中加載圖像，並且我們有自己的ImageIO API保存圖像。
