Detailed Description

Texture implementation that makes use of SFML.

Member Function Documentation

getInternalTexture() [1/2]

sf::Texture * tgui::BackendTextureSFML::getInternalTexture ( )

nodiscard

Returns a reference to the internal SFML texture.

Returns

Reference to internal texture

Warning

You are not allowed to change the size, pixels or smoothing of the texture

getInternalTexture() [2/2]

const sf::Texture * tgui::BackendTextureSFML::getInternalTexture ( ) const

nodiscard

Returns a const reference to the internal SFML texture.

Returns

Const reference to internal texture

loadTextureOnly()

bool tgui::BackendTextureSFML::loadTextureOnly ( Vector2u size, const std::uint8_t * pixels, bool smooth )

overridevirtual

Loads the texture from an array of 32-bits RGBA pixels, but don't take ownership of the pixels.

Parameters

size	Width and height of the image to create
pixels	Pointer to array of size.x*size.y*4 bytes with RGBA pixels, or nullptr to create an empty texture
smooth	Should the smooth filter be enabled or not?

Warning

Unlike the load function, loadTextureOnly won't store the pixels and isTransparentPixel thus won't work

Reimplemented from tgui::BackendTexture.

replaceInternalTexture()

void tgui::BackendTextureSFML::replaceInternalTexture

(

const sf::Texture &

texture

)

Replaces the internal texture by a different one.

Parameters

texture

Texture to copy

This will remove the pixel data stored by this object and reset its smoothing and size based on the new texture.

setSmooth()

void tgui::BackendTextureSFML::setSmooth ( bool smooth )

overridevirtual

Changes whether the smooth filter is enabled or not.

Parameters

smooth

True if smoothing should be enabled, false if it should be disabled

Reimplemented from tgui::BackendTexture.
