size Texture size

◆ sfTexture_createSrgbFromFile()
Create a new sRGB-enabled texture from a file.
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.
This load option is only useful in conjunction with an sRGB capable framebuffer. This can be requested during window creation.

-
filename Path of the image file to load area Area of the source image to load (NULL to load the entire image)
- Returns
- A new sfTexture object, or NULL if it failed
◆ sfTexture_createSrgbFromImage()

◆ sfTexture_createSrgbFromStream()

◆ sfTexture_destroy()

◆ sfTexture_generateMipmap()
bool sfTexture_generateMipmap | ( | sfTexture * | texture | ) |
Generate a mipmap using the current texture data.
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.
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.
- Returns
- true if mipmap generation was successful, false if unsuccessful
◆ sfTexture_getMaximumSize()
unsigned int sfTexture_getMaximumSize | ( | void | ) |
Get the maximum texture size allowed.
- Returns
- Maximum size allowed for textures, in pixels
◆ sfTexture_getNativeHandle()
unsigned int sfTexture_getNativeHandle | ( | const sfTexture * | texture | ) |
Get the underlying OpenGL handle of the texture.
You shouldn't need to use this function, unless you have very specific stuff to implement that SFML doesn't support, or implement a temporary workaround until a bug is fixed.
- Parameters
-
texture The texture object
- Returns
- OpenGL handle of the texture or 0 if not yet created
◆ sfTexture_getSize()
sfVector2u sfTexture_getSize | ( | const sfTexture * | texture | ) |
Return the size of the texture.
- Parameters
-
texture Texture to read
- Returns
- Size in pixels
◆ sfTexture_isRepeated()
bool sfTexture_isRepeated | ( | const sfTexture * | texture | ) |
Tell whether a texture is repeated or not.
- Parameters
-
texture The texture object
- Returns
- true if repeat mode is enabled, false if it is disabled
◆ sfTexture_isSmooth()
bool sfTexture_isSmooth | ( | const sfTexture * | texture | ) |
Tell whether the smooth filter is enabled or not for a texture.
- Parameters
-
texture The texture object
- Returns
- true if smoothing is enabled, false if it is disabled
◆ sfTexture_isSrgb()
bool sfTexture_isSrgb | ( | const sfTexture * | texture | ) |
Tell whether the texture source is converted from sRGB or not.
- Returns
- True if the texture source is converted from sRGB, false if not
◆ sfTexture_setRepeated()
void sfTexture_setRepeated | ( | sfTexture * | texture, |
bool | repeated | ||
) |
Enable or disable repeating for a texture.
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.
- Parameters
-
texture The texture object repeated True to repeat the texture, false to disable repeating
◆ sfTexture_setSmooth()
void sfTexture_setSmooth | ( | sfTexture * | texture, |
bool | smooth | ||
) |
Enable or disable the smooth filter on a texture.
- Parameters
-
texture The texture object smooth true to enable smoothing, false to disable it

- Parameters
-
