<p>It implements the same 2D drawing and OpenGL-related functions (see their base class <aclass="el"href="classsf_1_1RenderTarget.html"title="Base class for all render targets (window, texture, ...) ">sf::RenderTarget</a> for more details), the difference is that the result is stored in an off-screen texture rather than being show in a window.</p>
<p>Rendering to a texture can be useful in a variety of situations: </p><ul>
<li>precomputing a complex static texture (like a level's background from multiple tiles) </li>
<li>applying post-effects to the whole scene with shaders </li>
<li>creating a sprite from a 3D object rendered with OpenGL </li>
<li>etc.</li>

<p>Initially, both coordinate systems (world units and target pixels) match perfectly. But if you define a custom view or resize your render target, this assertion is not true anymore, i.e. a point located at (150, 75) in your 2D world may map to the pixel (10, 50) of your render target – if the view is translated by (140, 25).</p>

<p>Convert a point from target coordinates to world coordinates. </p>
<p>This function finds the 2D position that matches the given pixel of the render target. In other words, it does the inverse of what the graphics card does, to find the initial position of a rendered pixel.</p>
<p>Initially, both coordinate systems (world units and target pixels) match perfectly. But if you define a custom view or resize your render target, this assertion is not true anymore, i.e. a point located at (10, 50) in your render target may map to the point (150, 75) in your 2D world – if the view is translated by (140, 25).</p>
<p>For render-windows, this function is typically used to find which point (or object) is located below the mouse cursor.</p>
<p>This version uses a custom view for calculations, see the other overload of the function if you want to use the current view of the render target.</p>

<p>Restore the previously saved OpenGL render states and matrices. </p>

<p>Save the current OpenGL render states and matrices. </p>
<p>This function can be used when you mix SFML drawing and direct OpenGL rendering. Combined with popGLStates, it ensures that: </p><ul>
<li>SFML's internal states are not messed up by your OpenGL code </li>
<li>your OpenGL states are not modified by a call to a SFML function</li>
</ul>
<p>More specifically, it must be used around code that calls Draw functions. Example: </p><divclass="fragment"><divclass="line"><spanclass="comment">// OpenGL code here...</span></div><divclass="line">window.pushGLStates();</div><divclass="line">window.draw(...);</div><divclass="line">window.draw(...);</div><divclass="line">window.popGLStates();</div><divclass="line"><spanclass="comment">// OpenGL code here...</span></div></div><!-- fragment --><p>Note that this function is quite expensive: it saves all the possible OpenGL states and matrices, even the ones you don't care about. Therefore it should be used wisely. It is provided for convenience, but the best results will be achieved if you handle OpenGL states yourself (because you know which states have really changed, and need to be saved and restored). Take a look at the resetGLStates function if you do so.</p>

<p>Reset the internal OpenGL states so that the target is ready for drawing. </p>
<p>This function can be used when you mix SFML drawing and direct OpenGL rendering, if you choose not to use pushGLStates/popGLStates. It makes sure that all OpenGL states needed by SFML are set, so that subsequent <aclass="el"href="classsf_1_1RenderTarget.html#a12417a3bcc245c41d957b29583556f39"title="Draw a drawable object to the render target. ">draw()</a> calls will work as expected.</p>
<p>Example: </p><divclass="fragment"><divclass="line"><spanclass="comment">// OpenGL code here...</span></div><divclass="line">glPushAttrib(...);</div><divclass="line">window.resetGLStates();</div><divclass="line">window.draw(...);</div><divclass="line">window.draw(...);</div><divclass="line">glPopAttrib(...);</div><divclass="line"><spanclass="comment">// OpenGL code here...</span></div></div><!-- fragment -->
<p>Activate or deactivate the render-texture for rendering. </p>
<p>This function makes the render-texture's context current for future OpenGL rendering operations (so you shouldn't care about it if you're not doing direct OpenGL stuff). Only one context can be current in a thread, so if you want to draw OpenGL geometry to another render target (like a <aclass="el"href="classsf_1_1RenderWindow.html"title="Window that can serve as a target for 2D drawing. ">RenderWindow</a>) don't forget to activate it again.</p>

<p>The view is like a 2D camera, it controls which part of the 2D scene is visible, and how it is viewed in the render target. The new view will affect everything that is drawn, until another view is set. The render target keeps its own copy of the view object, so it is not necessary to keep the original one alive after calling this function. To restore the original view of the target, you can pass the result of <aclass="el"href="classsf_1_1RenderTarget.html#ad3b533c3f899d7044d981ed607aef9be"title="Get the default view of the render target.
