Interface Graphics</H2>

<DT><PRE>public interface Graphics</DL>
</PRE>



This interface encapsulates the communication with the graphics processor. It allows to retrieve <A HREF="../../../com/badlogic/gdx/graphics/GL10.html" title="interface in com.badlogic.gdx.graphics"><CODE>GL10</CODE></A>, <A HREF="../../../com/badlogic/gdx/graphics/GL11.html" title="interface in com.badlogic.gdx.graphics"><CODE>GL11</CODE></A> and
<A HREF="../../../com/badlogic/gdx/graphics/GL20.html" title="interface in com.badlogic.gdx.graphics"><CODE>GL20</CODE></A> instances depending on the available hardware and configuration of the <A HREF="../../../com/badlogic/gdx/Application.html" title="interface in com.badlogic.gdx"><CODE>Application</CODE></A>. Additionally it
features methods to generate <A HREF="../../../com/badlogic/gdx/graphics/Pixmap.html" title="class in com.badlogic.gdx.graphics"><CODE>Pixmap</CODE></A>s and <A HREF="../../../com/badlogic/gdx/graphics/Texture.html" title="class in com.badlogic.gdx.graphics"><CODE>Texture</CODE></A>s.



<A HREF="../../../com/badlogic/gdx/graphics/Texture.html" title="class in com.badlogic.gdx.graphics"><CODE>Texture</CODE></A>s can be either managed or not managed. Managed and Textures will be restored when the OpenGL context is lost.
An OpenGL ES context loss happens when a user pauses the Application ( <A HREF="../../../com/badlogic/gdx/ApplicationListener.html#pause()"><CODE>ApplicationListener.pause()</CODE></A>) and switches to
another application on Android. On the desktop there is no concept of context loss for OpenGL.



There are many more utility classes that are not directly generated by the <A HREF="../../../com/badlogic/gdx/Graphics.html" title="interface in com.badlogic.gdx"><CODE>Graphics</CODE></A> interfaces. See <A HREF="../../../com/badlogic/gdx/graphics/glutils/VertexArray.html" title="class in com.badlogic.gdx.graphics.glutils"><CODE>VertexArray</CODE></A>, <A HREF="../../../com/badlogic/gdx/graphics/glutils/VertexBufferObject.html" title="class in com.badlogic.gdx.graphics.glutils"><CODE>VertexBufferObject</CODE></A>, <A HREF="../../../com/badlogic/gdx/graphics/glutils/IndexBufferObject.html" title="class in com.badlogic.gdx.graphics.glutils"><CODE>IndexBufferObject</CODE></A>, <A HREF="../../../com/badlogic/gdx/graphics/Mesh.html" title="class in com.badlogic.gdx.graphics"><CODE>Mesh</CODE></A>, <A HREF="../../../com/badlogic/gdx/graphics/glutils/ShaderProgram.html" title="class in com.badlogic.gdx.graphics.glutils"><CODE>ShaderProgram</CODE></A> and <A HREF="../../../com/badlogic/gdx/graphics/glutils/FrameBuffer.html" title="class in com.badlogic.gdx.graphics.glutils"><CODE>FrameBuffer</CODE></A>,
<A HREF="../../../com/badlogic/gdx/graphics/g2d/BitmapFont.html" title="class in com.badlogic.gdx.graphics.g2d"><CODE>BitmapFont</CODE></A>, <A HREF="../../../com/badlogic/gdx/graphics/g2d/SpriteBatch.html" title="class in com.badlogic.gdx.graphics.g2d"><CODE>SpriteBatch</CODE></A> and so on. All these classes are managed, meaning they don't need to be reloaded on a
context loss. Explore the com.badlogic.gdx.graphics package for more classes that might come in handy.



All graphical resources, be the generated by the <A HREF="../../../com/badlogic/gdx/Graphics.html" title="interface in com.badlogic.gdx"><CODE>Graphics</CODE></A> interface or via a constructor must be disposed when
no longer used!
