<DL>
<DT><PRE>public interface <B>TextureData</B></DL>
</PRE>

<P>
Used by a <A HREF="../../../../com/badlogic/gdx/graphics/Texture.html" title="class in com.badlogic.gdx.graphics"><CODE>Texture</CODE></A> to load the pixel data. A TextureData can either return a <A HREF="../../../../com/badlogic/gdx/graphics/Pixmap.html" title="class in com.badlogic.gdx.graphics"><CODE>Pixmap</CODE></A> or upload the pixel data
 itself. It signals it's type via <A HREF="../../../../com/badlogic/gdx/graphics/TextureData.html#getType()"><CODE>getType()</CODE></A> to the Texture that's using it. The Texture will then either invoke
 <A HREF="../../../../com/badlogic/gdx/graphics/TextureData.html#consumePixmap()"><CODE>consumePixmap()</CODE></A> or <A HREF="../../../../com/badlogic/gdx/graphics/TextureData.html#consumeCompressedData()"><CODE>consumeCompressedData()</CODE></A>. These are the first methods to be called by Texture. After that
 the Texture will invoke the other methods to find out about the size of the image data, the format, whether mipmaps should be
 generated and whether the TextureData is able to manage the pixel data if the OpenGL ES context is lost.</p>
 
 In case the TextureData implementation has the type <A HREF="../../../../com/badlogic/gdx/graphics/TextureData.TextureDataType.html#Compressed"><CODE>TextureData.TextureDataType.Compressed</CODE></A>, the implementation has to generate the
 mipmaps itself if necessary. See <A HREF="../../../../com/badlogic/gdx/graphics/glutils/MipMapGenerator.html" title="class in com.badlogic.gdx.graphics.glutils"><CODE>MipMapGenerator</CODE></A>.</p>
 
 Before a call to either <A HREF="../../../../com/badlogic/gdx/graphics/TextureData.html#consumePixmap()"><CODE>consumePixmap()</CODE></A> or <A HREF="../../../../com/badlogic/gdx/graphics/TextureData.html#consumeCompressedData()"><CODE>consumeCompressedData()</CODE></A>, Texture will bind the OpenGL ES
 texture.</p>
 
 Look at <A HREF="../../../../com/badlogic/gdx/graphics/glutils/FileTextureData.html" title="class in com.badlogic.gdx.graphics.glutils"><CODE>FileTextureData</CODE></A> and <A HREF="../../../../com/badlogic/gdx/graphics/glutils/ETC1TextureData.html" title="class in com.badlogic.gdx.graphics.glutils"><CODE>ETC1TextureData</CODE></A> for example implementations of this interface.
