如何将BufferedImage转换为Texture？

Question

I am trying to convert a BufferedImage to a Texture from Slick2D. I have tried BufferedImageUtil.getTexture() , but either I am using it wrong, or it's not working (returns only one brown pixel out of a 32x32 image)

How can I convert a BufferedImage to a Texture ?

Answer 1

You are probably using it wrong, but as you do not provide any source code of your implementation I can only guess.

The syntax for [BufferedImage.get(...)]( http://slick.ninjacave.com/javadoc-util/org/newdawn/slick/util/BufferedImageUtil.html#getTexture(java.lang.String , java.awt.image.BufferedImage)) is:

public static Texture getTexture(java.lang.String resourceName,
                                 java.awt.image.BufferedImage resourceImage)
                          throws java.io.IOException

Parameters:
  resourceName - The location of the resource to load
  resourceImage - The BufferedImage we are converting
Returns:
  The loaded texture

I used this once when setting up my own fonts and I converted the BufferedImages (resulting from a splitImage operation of a bigger image with all characters on it) to Textures. It worked just fine for me, I ignored the resourceName parameter though.

So this works for me:

BufferedImage image = ImageIO.read(new File(imagePath));
Texture texture = BufferedImageUtil.getTexture("", image); 

Looking at the source code of this method, the resourceName parameter should not have any impact on the method at all.

So just try it with my example and then try to implement this in your project, if you have any troubles with that let me know in the comments and I can help you.

Edit

There are some fundamental flaws with your code:

• ( This is why your code doesn't work at all/throws an exception ). You load the texture with BufferedImage texture = ImageIO.read(new File(path+ "/texture.png")); in your constructor, which does not change the texture parameter in your block but rather just creates a local unused variable. Fix this by removing the BufferedImage in that line.

• (Almost) everything there is static. That makes no sense, as each block for example can have its own textures and parameters.

• Please obey the Java naming conventions. Class names are upper camel case ( MyClass ), variable names lower camel case ( myVariable ), methods are lower camel case ( myMethod ), constants are upper case ( MY_CONSTANT ) and packages are lower case ( mypackage ).

Answer 2

Load texture:

Texture texture; texture = TextureLoader.getTexture("PNG", new FileInputStream(new File("res/image.png")));

If it doesn't fix your problem, then it is something wrong with the way you bind it.
