Help! My NinePatch ProgressBar background is not appearing when the slice values are set

I need help! What am I doing wrong? When I remove the 4 integer slice values, the background is displayed (of course, stretched very weirdly). However, when I put in the 4 slice values, the NinePatch doesn’t display at all.

progressBar, progressBarStyle and background are defined elsewhere in the class.

add(progressBar=new ProgressBar(
	0f,
	100f,
	0.1f,
	false,
	progressBarStyle=new ProgressBar.ProgressBarStyle(
		background=new NinePatchDrawable(new NinePatch(
			TextureRegionFinder.findTextureRegion(
				arena.tuxFight.assetManager,
				"barbackground.png"
			),
			11,
			11,
			11,
			11
		)),
		null
	)
));
progressBar.setRound(false);
progressBar.setBounds(0,0,width,height);
progressBar.setValue(MathUtils.clamp(value,0f,100f));
progressBar.setAnimateDuration(1f);
background.setMinSize(width,height);
background.tint(endColor);

progressBarStyle.knobBefore=new BaseDrawable(){
	{
		setMinHeight(progressBar.getHeight());
	}
	ShapeRenderer shapeRenderer=new ShapeRenderer();
	@Override
	public void draw(Batch batch,float x,float y,float width,float height){
		batch.end();
		shapeRenderer.setProjectionMatrix(batch.getProjectionMatrix());
		shapeRenderer.begin(ShapeRenderer.ShapeType.Filled);
		shapeRenderer.rect(x+7f,y+7f,(width-14f)*0.25f,height-14f,zeroColor,midColor,midColor,zeroColor);
		shapeRenderer.rect(x+7f+(width-14f)*0.25f,y+7f,(width-14f)*0.75f,height-14f,midColor,endColor,endColor,midColor);
		shapeRenderer.end();
		batch.begin();
	}
};

Please use the Discord for help requests; the #scene2d, #help-1 or #help-2 topics would all be appropriate avenues. If you don’t have Discord, the libGDX server link is here. This doesn’t look like a bug or other issue in libGDX, but I’m not comfortable enough with 9patches to say that with confidence, so I’ll leave this open for now.

As an aside, you may want ShapeDrawer rather than ShapeRenderer, to avoid frequently ending and beginning the batch.

Hi, I found out the problem. The NinePatch simply doesn’t work when the TextureRegion is flipped (vertically).

See https://github.com/siauderman/NinePatchTest

I believe this is a bug. Surely NinePatches should work even when the TextureRegion is flipped.
