Detailed Description

Texture implementation that makes use of modern OpenGL.

Member Function Documentation

getInternalTexture()

TGUI_NODISCARD unsigned int tgui::BackendTextureOpenGL3::getInternalTexture

(

)

const

Returns the id of the OpenGL texture.

Returns

Texture id

loadTextureOnly()

bool tgui::BackendTextureOpenGL3::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.

setSmooth()

void tgui::BackendTextureOpenGL3::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.
