<p><aclass="el"href="classsf_1_1Texture.html"title="Image living on the graphics card that can be used for drawing. ">sf::Texture</a> stores pixels that can be drawn, with a sprite for example.</p>
<p>A texture lives in the graphics card memory, therefore it is very fast to draw a texture to a render target, or copy a render target to a texture (the graphics card can access both directly).</p>
<p>Being stored in the graphics card memory has some drawbacks. A texture cannot be manipulated as freely as a <aclass="el"href="classsf_1_1Image.html"title="Class for loading, manipulating and saving images. ">sf::Image</a>, you need to prepare the pixels first and then upload them to the texture in a single operation (see <aclass="el"href="classsf_1_1Texture.html#ae4eab5c6781316840b0c50ad08370963"title="ServerUpdate the whole texture from an array of pixels. ">Texture::update</a>).</p>
<p><aclass="el"href="classsf_1_1Texture.html"title="Image living on the graphics card that can be used for drawing. ">sf::Texture</a> makes it easy to convert from/to <aclass="el"href="classsf_1_1Image.html"title="Class for loading, manipulating and saving images. ">sf::Image</a>, but keep in mind that these calls require transfers between the graphics card and the central memory, therefore they are slow operations.</p>
<p>A texture can be loaded from an image, but also directly from a file/memory/stream. The necessary shortcuts are defined so that you don't need an image first for the most common cases. However, if you want to perform some modifications on the pixels before creating the final texture, you can load your file to a <aclass="el"href="classsf_1_1Image.html"title="Class for loading, manipulating and saving images. ">sf::Image</a>, do whatever you need with the pixels, and then call <aclass="el"href="classsf_1_1Texture.html#abec4567ad9856a3596dc74803f26fba2"title="Load the texture from an image. ">Texture::loadFromImage</a>.</p>
<p>Since they live in the graphics card memory, the pixels of a texture cannot be accessed without a slow copy first. And they cannot be accessed individually. Therefore, if you need to read the texture's pixels (like for pixel-perfect collisions), it is recommended to store the collision information separately, for example in an array of booleans.</p>
<p>Like <aclass="el"href="classsf_1_1Image.html"title="Class for loading, manipulating and saving images. ">sf::Image</a>, <aclass="el"href="classsf_1_1Texture.html"title="Image living on the graphics card that can be used for drawing. ">sf::Texture</a> can handle a unique internal representation of pixels, which is RGBA 32 bits. This means that a pixel must be composed of 8 bits red, green, blue and alpha channels – just like a <aclass="el"href="classsf_1_1Color.html"title="Utility class for manipulating RGBA colors.

This mode is used internally by the graphics classes of SFML, it makes the definition of texture coordinates more intuitive for the high-level API, users don't need to compute normalized values.</p>

<p>Generate a mipmap using the current texture data. </p>
<p>Mipmaps are pre-computed chains of optimized textures. Each level of texture in a mipmap is generated by halving each of the previous level's dimensions. This is done until the final level has the size of 1x1. The textures generated in this process may make use of more advanced filters which might improve the visual quality of textures when they are applied to objects much smaller than they are. This is known as minification. Because fewer texels (texture elements) have to be sampled from when heavily minified, usage of mipmaps can also improve rendering performance in certain scenarios.</p>
<p>Mipmap generation relies on the necessary OpenGL extension being available. If it is unavailable or generation fails due to another reason, this function will return false. Mipmap data is only valid from the time it is generated until the next time the base level image is modified, at which point this function will have to be called again to regenerate it.</p>

<p>Repeating is involved when using texture coordinates outside the texture rectangle [0, 0, width, height]. In this case, if repeat mode is enabled, the whole texture will be repeated as many times as needed to reach the coordinate (for example, if the X texture coordinate is 3 * width, the texture will be repeated 3 times). If repeat mode is disabled, the "extra space" will instead be filled with border pixels. Warning: on very old graphics cards, white pixels may appear when the texture is repeated. With such cards, repeat mode can be used reliably only if the texture has power-of-two dimensions (such as 256x128). Repeating is disabled by default.</p>

<p>When the filter is activated, the texture appears smoother so that pixels are less noticeable. However if you want the texture to look exactly the same as its source file, you should leave it disabled. The smooth filter is disabled by default.</p>

<p>When providing texture data from an image file or memory, it can either be stored in a linear color space or an sRGB color space. Most digital images account for gamma correction already, so they would need to be "uncorrected" back to linear color space before being processed by the hardware. The hardware can automatically convert it from the sRGB color space to a linear color space when it gets sampled. When the rendered image gets output to the final framebuffer, it gets converted back to sRGB.</p>
<p>After enabling or disabling sRGB conversion, make sure to reload the texture data in order for the setting to take effect.</p>
<p>This option is only useful in conjunction with an sRGB capable framebuffer. This can be requested during window creation.</p>
