(Java LibGDX) How do I resize my textures in LibGDX?
提问by user2445723
I have been fooling around with LibGDX for a while now, and wanted to easily port my programs to different systems. I have a background texture, which I want to scale to the currently used resolution. The image is 1920x1080, how do I change it to the currently used resolution at runtime?
我一直在玩 LibGDX 一段时间，想轻松地将我的程序移植到不同的系统。我有一个背景纹理，我想将其缩放到当前使用的分辨率。图像是 1920x1080，如何在运行时将其更改为当前使用的分辨率？

If you want to scale at drawing time use:
如果要在绘图时缩放，请使用：
Pixmap pixmap200 = new Pixmap(Gdx.files.internal("200x200.png"));
Pixmap pixmap100 = new Pixmap(100, 100, pixmap200.getFormat());
pixmap100.drawPixmap(pixmap200,
0, 0, pixmap200.getWidth(), pixmap200.getHeight(),
0, 0, pixmap100.getWidth(), pixmap100.getHeight()
);
Texture texture = new Texture(pixmap100);
pixmap200.dispose();
pixmap100.dispose();

batch.begin();
batch.draw(yourtexture, 0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
batch.end();
Using the camera viewport also works:
使用相机视口也有效：
batch.begin();
batch.draw(yourtexture, 0, 0, cam.viewportWidth, cam.viewportHeight);
batch.end();
