Detailed Description

Texture implementation that makes use of modern OpenGL ES.

Member Function Documentation

◆ getInternalTexture()

unsigned int tgui::BackendTextureGLES2::getInternalTexture ( ) const

Returns the id of the OpenGL texture.

Returns
Texture id

◆ loadTextureOnly()

bool tgui::BackendTextureGLES2::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
sizeWidth and height of the image to create
pixelsPointer to array of size.x*size.y*4 bytes with RGBA pixels, or nullptr to create an empty texture
smoothShould 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::BackendTextureGLES2::setSmooth ( bool  smooth)
overridevirtual

Changes whether the smooth filter is enabled or not.

Parameters
smoothTrue if smoothing should be enabled, false if it should be disabled

Reimplemented from tgui::BackendTexture.
